If you spend many hours in front of the computer, having Windows customized to your liking makes all the difference. A well-organized taskbar, a clean Start menu, and a desktop free of visual clutter. They make working, studying, or playing much more comfortable. Windows 10 and Windows 11 offer numerous options to customize the interface, some of which are handled through the system itself, while others require using the Registry Editor.
In this guide we will see, step by step, How to use the Registry Editor and Windows customization options To modify the taskbar, move it, change its alignment, adjust its transparency, control which applications are pinned, manage virtual desktops, configure the Notification Center, and much more. All explained in Spanish (Spain), with warnings where caution is advised and tips designed for both home users and professional environments.
How does the taskbar work in Windows?
The taskbar is that element you usually see at the bottom of the screen where things are displayed the icons of open applications, pinned shortcuts, the Home button, the date, and the notification areaIts main purpose is to give you quick access to programs and allow you to switch between windows smoothly.
When an application is running, Its icon appears in the taskbar with a line or underline. This indicates that it's running. The active window is usually highlighted with the system's accent color, helping you identify which program you're currently using. All of this is customizable: which applications remain pinned, how they're ordered, where the bar is positioned, and how it behaves.
Pin, unpin, and rearrange apps on the taskbar
To keep your most frequently used programs always at hand, you can pin them permanently to the taskbarThis saves you from having to search for them in the Start menu or on the desktop every time you need them.
A very straightforward way to do this is to use the Windows search bar. Type the application name in the search box on the taskbar, Right-click on the result and select “Pin to taskbar”From that moment on, the icon will remain fixed even when you close the application.
Another quick way is to take advantage of the fact that the app is already open. If you see its icon in the taskbar, right-click on it. and select the "Pin to taskbar" option. Again, the icon will no longer disappear when you close the program.
You can also pin shortcuts that you have on the desktop or in the Start menu. In Windows 11, if you are on the desktop, right-click on the shortcut.To access the app, go to "Show more options" and then select "Pin to taskbar." From the Start menu, simply search for the app, right-click, go to "More," and then click "Pin to taskbar."
If later you decide that you no longer want to have that program so readily available, To unpin it, simply right-click on its icon in the taskbar. and select “Unpin from taskbar”. This frees up visual space for what you actually use.
The order of the icons can also be adapted to your preferences. To rearrange apps on the taskbar, drag the icon From its current position to the new location within the bar itself. No extra menu is needed; simply drag and drop.
Change the position and alignment of the taskbar
In Windows 11, by default, the taskbar is at the bottom of the screen and the icons are displayed macOS-style focusedThis can be changed to some extent through the settings and, more advancedly, through the Registry.
Align icons to the left from the settings
If you prefer the classic Windows look, with the Start button on the left, you can move the alignment without touching the RegisterRight-click on an empty area of the taskbar, go to “Taskbar settings” or “Settings > Personalization > Taskbar” and look for the “Taskbar behavior” section.
In that section you will see the option “Taskbar alignment”. Expand the panel and change from “Center” to “Left”You'll see how the Start button, search, and the rest of the icons move to the left side, similar to Windows 10, maintaining the modern design but with a more familiar feel.
Automatically hide the taskbar
If you want to squeeze out a little more screen space, you can Configure the toolbar to hide when you're not using itAgain, from the taskbar settings, enable the "Automatically hide the taskbar" option.
With that box enabled, The bar retracts and only appears when you move the mouse to the corresponding edge.It's very useful on small screens or when you want a cleaner work surface for video editing, programming, or gaming.
Move the taskbar to another edge using the Registry Editor
Here's where things get tricky: Change the position of the taskbar in Windows 11 to the top, left, or right This can no longer be done with a graphical menu; it requires using the Registry Editor. Proceed with caution, as an error in the Registry can cause unexpected behavior.
The first step is to open the Registry Editor. Press Windows + R, type “regedit” and confirm with EnterOr search for “Registry Editor” in the search box. Accept the account control warning if it appears.
Next, in the Editor's address bar, enter the appropriate path. In Windows 11, the path is:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\StuckRects3
If you're doing it by hand, unfold the branches until you reach StuckRects3Inside you'll see a binary value called "Settings" (in some translations it appears as "Configuration"). Double-click on it to open the hexadecimal editor.
In that window you can modify a value that indicates where the bar is placed. In the second row of values, locate the fifth byteBy default, "03" usually appears, which corresponds to the bar located at the bottom.
Depending on the value you put in that byte, the bar will move to a different edge of the screen. The codes are:
- 00: taskbar on the left side of the screen.
- 01: taskbar at the top.
- 02: taskbar on the right side.
- 03: taskbar at the bottom (default).
Change the corresponding value (for example, from 03 to 01 if you want the bar at the top) and press “OK”. From here you still won't see any changes because Windows Explorer still needs to be restarted.
To apply the change without restarting the computer, Open Task Manager with Control + Shift + EscIf you see the simplified view, click on "More details". Within the list of processes, find "Windows Explorer" or "File Explorer", right-click on it, and select "End task".
Then, from the Task Manager itself, Go to “File > Run new task” and type “explorer.exe” To relaunch it, the bar will then appear on the edge you configured. Note that in some modern builds of Windows 11, placing it on the sides can cause scaling or interface issues, as Microsoft no longer officially supports this.
Deep customization of the taskbar using XML and Registration (OEM and enterprises)

In professional environments or for equipment manufacturers, Microsoft allows Define preconfigured taskbar layouts using an XML fileThis technique is designed more for corporate Windows images than for the home user, but it's worth knowing about.
OEMs can pin up to three additional applications to the taskbar, in addition to the icons that Windows includes by default: Home, Search, Task View, Mail, Microsoft Edge, File Explorer, and Microsoft StoreThese system icons cannot be removed or changed using this method.
The recommended mechanism is the file TaskbarLayoutModification.xml, which is normally placed in C:\Windows\OEM\TaskbarLayoutModification.xmlIn order for Windows to know that it has to use it, you have to create a Registry key called LayoutXMLPath in:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer
The key must be set before the "specialize" configuration phase when creating or capturing the system image. This way, When the system is deployed on other computers, the taskbar will adopt the design defined in the XML.which may vary by region (for example, one design for US/GB and another for CN/TW).
This XML file mixes definitions for both classic and UWP applications. For desktop apps, shortcut paths are used. .lnk from the Start menu, for example %ALLUSERSPROFILE%\Microsoft\Windows\Start Menu\Programs\Accessories\Paint.lnkFor Universal Windows Platform (UWP) apps, their AppUserModel identifiers are specified.
The complete process in image scenarios includes: installing Windows on a technical computer, Enter audit mode with CTRL + SHIFT + F3, define the Registry key with a command reg add, copy the XML to the agreed path, generalize the image with Sysprep /generalize /oobe /shutdownBoot into Windows PE and capture the image with DISM for use on other computers.
If Windows finds a valid XML file modifying the taskbar, Ignore any unattended legacy configurations (TaskbarLinks)Only if it cannot locate the XML or if the XML is invalid will it resort to the classic unattended parameters. And if there is neither XML nor legacy configuration, it will only display the standard Windows anchors.
Adjust taskbar transparency and other useful Registry keys
On some devices, especially those with OLED screens and dark themes, it's advisable Increase the transparency of the taskbar to avoid such harsh contrast. The default setting is around 15% transparency, but Microsoft recommends increasing it to 40% for a more balanced result.
To do this, you need to create a Registry key called UseOLEDTaskbarTransparency (DWORD type) in:
HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced
By setting its value appropriately and restarting the session, The bar will adopt a higher level of transparency, blending better with dark backgrounds, especially in OLED environments.
Another interface-related key that may appear in OEM environments is the one that enables the Color profile change button in the Action CenterIf at least two ICC profiles are installed on the main screen and the key is created:
HKLM\Software\Microsoft\Windows\Shell\OEM\QuickActions\ColorProfileQuickAction = 0x1 (DWORD)
then users will be able to Activate the "Color Profile" quick action in the Notification CenterThis makes it easy to switch between profiles without having to go into advanced settings.
Advanced control of the taskbar from applications (Electron, etc.)
If you develop applications for Windows, especially with frameworks like Electron, you have access to Specific APIs to integrate with the taskbar in a very powerful wayThese options are interesting for offering a richer user experience.
JumpLists and user tasks
Windows allows an application icon to appear on the taskbar display a custom context menu with quick actions, known as JumpList. These are the options that appear when you right-click on the app icon.
In Electron, you can configure these tasks using app.setUserTasksDefining shortcuts that open the app with specific arguments (for example, “Compose new email”, “Open calendar”, or “Create new document”) without requiring the application to be open. It is recommended that These tasks should be few, clear, frequent, and non-promotional., so as not to overwhelm the user.
If at any time you wish to remove these tasks, simply Call app.setUserTasks with an empty arrayThis clears the JumpList. Keep in mind that as long as the application remains installed, the paths and icons used in these tasks must still exist, because Windows may continue to display the list even after you close the app.
Thumbnails with buttons (thumbnail toolbar)
Another very useful feature is the miniature toolbar that appears when you hover the mouse over the app icon in the taskbar or by using Alt+Tab. It allows you to add buttons (up to seven) with actions such as play, pause, mute or stop, typical in media players.
In Electron this is managed with BrowserWindow.setThumbarButtonspassing an array with the definition of each button (icon, description, identifier, state). If you later want to remove that bar, you can call the method again with an empty array and Windows will remove the thumbnail buttons.
Overlay icons and “Flash Frame” effect
Taskbar icons can also display small overlapping symbols which indicate important states, such as new messages, disconnection, errors, etc. In Electron, this is configured with BrowserWindow.setOverlayIcon, passing the icon and the description.
Additionally, you can attract the user's attention by activating the taskbar button blinking (similar to dock bounce in macOS). With BrowserWindow.flashFrame(true) The button starts flashing until the user focuses on the window or manually deactivates it with flashFrame(false)It is important not to overuse this effect so as not to tire the user.
Customize the Windows 10 and Windows 11 interface: themes, colors, and background
Beyond the taskbar, both Windows 10 and Windows 11 allow touch on virtually every visual aspect: desktop background, themes, colors, fonts, and soundsThis is not only aesthetic; it can also help reduce eye strain and improve concentration.
From “Settings > Personalization”, you can change the Wallpaper options include still image, solid color, or slideshowIn the “Colors” section, you choose light or dark mode, adjust the accent color (which is applied to windows, buttons, and the taskbar), and decide if you want transparency in the interface.
The themes group together several of these preferences: pack of backgrounds, color scheme and soundsYou can use the default themes, download new ones from the Microsoft Store, or create your own and save it. This is especially useful if you want a more understated "work" mode and a more colorful "leisure" mode.
Organize your desktop, icons, and widgets
The desktop is another key point of customization. A desktop with well-organized icons and no excessive elements greatly improves the feeling of control.In Windows 10 and 11 you can change the size of the icons from the context menu (right click > View) or by holding Control and moving the mouse wheel.
To maintain order, you can activate options such as “Auto-organize icons” or “Sort by”You can create themed folders (work, games, projects) and delete shortcuts you no longer use. You also have the option to completely hide desktop icons, leaving only the background.
If you like to go a step further, third-party tools such as Rainmeter allows you to add fully customized widgets to the desktop: advanced clock, weather, CPU usage, task lists, multimedia controls, etc. In Windows 11, you also have the integrated Widgets panel, which displays news, weather, calendar, and other configurable items.
Setting and customizing the Start menu
The Start menu remains the central hub for many tasks. From there you can access applications, recent documents, and system toolsPersonalizing it saves you time every day.
In Windows 10, you can Pin and unpin tiles, resize them, group applications into folders and choose whether you want full-screen Start. In Windows 11, the design has changed, with a pinned apps area and a "Recommended" area.
To add an app to Start, simply Right-click on the app in the list and choose “Pin to Start”To remove it, click "Unpin from Start." You can drag the icons to rearrange them, and if you place two together, an editable folder with a custom name will be created.
The "Recommended" section in Windows 11 shows recently used files and apps. If you find it confusing or are concerned about privacy, you can Clear it manually from the context menu (“Clear all recommendations”) or adjust the type of content displayed in the Start menu settings. Third-party tools like Start11 allow for even deeper menu customization.
Windows Search: “Search the Internet and Windows”
The search box integrated into the taskbar is much more than a simple local search engine. It allows you to find applications, files, settings, and also perform web searches. via Bing. It's a great shortcut for opening almost anything without navigating through menus.
When you write something, you can Filter results by category (Applications, Documents, Web, Settings, etc.). Additionally, in “Settings > Privacy > Search permissions > Search Windows” you can choose between a classic mode (only libraries and desktop) or an enhanced mode (all folders and drives), and you can exclude specific paths.
If you don't want the search engine to show you internet suggestions, You can disable web recommendationsso that the search box focuses on the content of your device. You can also clear your search history and disable cloud syncing to ensure that the results are purely local.
Virtual desktops to organize your workflow
Windows 10 and 11 virtual desktops are a productivity gem. They allow you to create several independent "desktops", each with its own open windowsso that you separate work, leisure, studies, or different projects.
They are managed from the "Task View" button on the taskbar or with the combination Win + TabThere you can create new desktops, switch between them, move windows from one to another, and close the ones you no longer need. You can also use shortcuts like Win + Ctrl + Left/Right Arrow to jump between desks on the fly.
A good practice is to give each desk a purpose: one for mail and documents, another for research, another for leisureThis reduces distractions and prevents you from wasting time searching for a specific window among a sea of icons in the bar.
Notification and Quick Action Center
The Notification Center (or Activity Center) groups All system and application alerts, plus a quick button area to activate Wi-Fi, Bluetooth, airplane mode, brightness, night mode and other settings.
From “Settings > System > Notifications and actions” you can Choose which apps can show notifications, whether you want pop-up banners, sounds, and what priority you give them.You can also activate Focus Assist, which filters notifications according to rules (priority only, alarms only, scheduled times, during games or screen mirroring).
Rapid actions can be reorganized so that The buttons you use most (like brightness, Wi-Fi, or mobile hotspot) are always within easy reachIn some versions, you'll see a pencil icon or a link to "Edit quick actions," which lets you add, remove, or move tiles. The colors and transparency of the Notification Center depend on the theme and system color settings.
Other advanced visual settings: pointers, icons, sounds, lock screen, and fonts
Beyond the taskbar and Start menu, Windows offers a lot of small details that you can tweak to make the system more your own without losing stability.
In the mouse settings (Control Panel or Settings > Devices > Mouse) you can change the pointer scheme, use animated (.ani) or static (.cur) cursors and restore the default values if you change your mind. Changing folder icons (right-click > Properties > Customize > Change Icon) helps you distinguish projects at a glance.
The system's sound section allows assign different tones to events such as notifications, errors, logins or logoutsYou can choose from Windows sounds or upload your own .wav files. If you prefer complete silence, simply select a sound-free option.
The lock screen is configured from “Personalization > Lock screen”, where you choose If you want a still image, Windows Spotlight, or photo slideshowand which apps can display quick information (email, calendar, weather, etc.). You can also decide whether the lock screen background is displayed on the login screen.
Regarding fonts, Windows 10 and 11 don't offer a simple global font change, but you can Adjust the text size in “Accessibility > Text Size”and modify specific sources through the Registry or third-party applications. As always, any changes to the Registry should be preceded by a backup.
Performance and security settings when customizing Windows
All this customization comes at a price if it's not done wisely: Too many visual effects, widgets, and background applications can slow down the system.That's why it's important to balance aesthetics and performance.
In “System > About > Advanced system settings > Performance” you can open the visual effects options and choose between “Adjust for best performance” or manually select which animations you want to keepDisabling shadows, transitions, and transparencies often provides a small boost in smoothness, especially on modest computers.
The “Background apps” tab in Settings lets you prevent certain apps from continuing to run even when you don't have them open.This saves battery and resources. It's also a good idea to check startup programs in Task Manager to prevent half a dozen applications from launching every time you turn on your PC.
Regarding safety, whenever you go to Editing the Registry (regedit) creates a system restore point and/or exports the keys you are going to change.Use an administrator account only when necessary, and download themes, icons, or customization tools only from trusted sources. Keeping Windows and drivers up to date helps prevent compatibility issues and security vulnerabilities.
With all these options at hand, it's possible to transform the Windows interface into a work or leisure environment that suits you: A taskbar placed wherever it's most convenient for you, well-organized icons, clean Start menus, distinct virtual desktops, and a Notification Center tailored to your workflow.If you also take care of performance and make changes to the Registry respectfully, you can get the most out of the system without sacrificing stability.
