When a system like Windows 11 SE or an older version of Windows 11 becomes unsupportedThe logical question is: “Now what do I do with my computer?” It’s not just an annoying notification on the screen; it implies real changes in security, stability, and updates.
Furthermore, conflicting messages from Windows Update Messages like “Your Windows has reached end of service” while everything seems to be working fine can drive anyone crazy. Let's take a closer look at what end of support means, what options you have to stay protected, and how to fix the classic update problems that are causing so many headaches.
What does it mean that Windows 11 SE (or your version) is reaching its end?
When Microsoft indicates that a specific edition or version of Windows reaches the end of its life cycleIt is saying that, from a certain date, that system will no longer have: free security updates, bug fixes, or standard technical support.
In practice, this means that Your computer becomes more vulnerable to malware, viruses, and attacksBecause security vulnerabilities that are discovered are no longer patched. For daily use with an internet connection, that's a risk that, frankly, isn't worth it.
Microsoft follows a fairly strict maintenance scheduleFor consumer versions (Home, Pro, Pro for Workstations, Pro Education), support typically lasts around 24 months from release. After that time, the idea is that you upgrade to the next version of Windows 11.
End of support for early versions of Windows 11
The clearest example is Windows 11 21H2, the first major version of the system. All of its home editions (Home, Pro, Pro for Workstations and Pro Education) reached their end of life in October 2023, following Microsoft's own roadmap.
This means that Anyone who remains on 21H2 will be left without security patches and without support.The solution in these cases is very simple: upgrade to a more modern version, such as 22H2, 23H2 or 24H2, which do receive maintenance.
To check which version you have installed, you can use the classic command winverPress the Windows key + R, type “winver”, and you’ll see an “About Windows” window with the version (for example, 21H2, 22H2, etc.). If it still shows 21H2 or a very old build, it’s time to take action.
Windows 10 is also shutting down: impact on migration to Windows 11
Another factor that complicates everything is that Windows 10 also has an expiration dateFree support (default security updates) ends on October 14, 2025. After that date, a Windows 10 PC without special support contracts will be vulnerable.
This causes that hundreds of millions of computers worldwide may need to migrate Windows 11 will be affected very quickly. In countries like Spain alone, we're talking about several million affected computers that, sooner or later, will have to be updated or face the risk.
Since its launch in October 2021, Windows 11 has been gaining market share. And it's already on more than 400 million devices. Even so, it still lags behind the nearly 1.000 billion machines running Windows 10, but that balance will shift as Windows 10 support nears its end.
Why are Windows updates so important?
Windows updates, the famous Windows UpdateThey are not a whim: they correct bugs, close vulnerabilities, and improve compatibility with new hardware and applications.
We can distinguish between two main types of updates in Windows 11:
- Monthly cumulative updatesThey include security patches, bug fixes, and minor tweaks. They accumulate (by May 2025 there were already more than forty).
- Feature Updates (21H2, 22H2, 23H2, 24H2): These are "big jumps" in version that add important features, interface changes, support for new technologies (e.g., Wi-Fi 7), etc.
The rollout of these updates is Highly recommended to keep your equipment protectedAlthough the experience may not always be perfect, accumulating uninstalled security patches leaves doors open to potential attacks.
Windows Update stops updating or displays strange messages
A fairly common problem is that Windows Update starts behaving erratically: progress bars that freeze, mysterious error codes, "end of service" messages, or contradictory notices about your version.
It's possible that you're already on Windows 11 (for example, Home 22H2) and yet, A message will appear indicating that the system has reached the end of service.This can be due to several factors: a major update pending, a poorly executed migration, a version detection failure, or even a botched edition/license change.
It is also common for the download of a new version is blockedthat the progress percentage remains fixed or that, after reaching 98-99%, Windows announces that "something has not gone as planned" and automatically uninstalls the patch.
The Windows Update cache: the silent enemy
One of the most frequent causes of update errors is the Windows Update cache folderEach time the system prepares an update, it creates a set of temporary files that store the components necessary for the installation.
These files are stored in the folder software distributionwithin the main Windows directory. Its function is to allow the system to continue a download or installation without repeating work, or to reuse part of the downloaded data in subsequent updates.
The problem comes when one of those temporary files gets corruptedWindows often tries to reuse these files, and if they're corrupted, the update installation will fail repeatedly. To make matters worse, the folder isn't obvious, and there's no clear message saying "the problem is with the cache."
The solution is through delete the contents of SoftwareDistributionBut be careful: do not delete the folder itself, only what is inside, and do so with the Windows Update-related services stopped to avoid crashes.
Specific errors with Windows 11 24H2 and problematic patches
The big update Windows 11 24H2The update, which brought support for Wi-Fi 7, improvements to the taskbar and new power options, was accompanied by a good number of problems reported by users.
Mouse pointer disappears
One of the most notorious failures was that The cursor disappeared in Chromium-based applications (Chrome, Edge, and other similar browsers). The system continued to function, but working in the browser without a pointer is, to put it mildly, infuriating.
An 8,63 GB cache that cannot be deleted
Another bug in 24H2 was the creation of a gigantic update cache folder of over 8,6 GB which was not automatically deleted. Traditional methods such as Disk Cleanup or the SFC command failed to make it disappear.
In many cases, The only way to recover that space was a clean Windows installation, which is quite aggressive for what, in theory, should be a simple update.
The patch that breaks File Explorer
The security patch KB5051987Released on February 11, it also became famous for the wrong reasons: it provoked serious errors in File Explorer (which would stop responding or not even open) and errors during installation that could render equipment unusable.
Interestingly, the process explorer.exe was still running in the backgroundwhich pointed more to a problem with the browser interface than a total system crash.
Updates that never finish and blue screens
In other cases, the update associated with these patches did not complete. The installation would freeze at varying percentagesAnd in the end, the system would revert the changes with the message that something had gone wrong.
In the most serious scenarios, this led to blue screensstartup problems or a general drop in performanceSome media outlets went so far as to describe the March update of Windows 11 24H2 as riddled with bugs, citing error codes such as 0x800f0993, 0x800F081F, 0x80070032 or 0xC004F211.
Incompatible drivers and update blocks
Microsoft eventually located part of the problem in an incompatible driver called “sprotect.sys” by SenseShield Technologyused by certain security software and business solutions, often installed silently alongside other applications.
To avoid damage, An update block was imposed with ID 56318982 on systems that use that driver. On those computers, Windows 11 24H2 was no longer offered through Windows Update until the incompatibility was resolved.
Bluetooth, camera, and game issues with updates
The problems weren't limited to the browser or the installation. Many users reported that after installing Windows 11 24H2 KB5050009, their Bluetooth devices stopped working properly.
The most frequent cases were Bluetooth headphones that stopped working After the update, unpairing and re-pairing, resetting the adapter, or restarting the computer didn't fix anything. For many people, the only solution was to uninstall the patch.
Something similar happened with external webcams and monitors with integrated cameras (like several Dell 4K models). The system warned that the device could not start, even though the driver was correctly installed.
To top it all off, there were complaints about combinations like Ctrl+Alt+Delete and the Task Manager that stopped working in certain situations, as well as games (Fortnite, Assassin's Creed and older titles) that suffered errors, crashes or endless restart requests.
In some cases, Smart App Control started blocking legitimate system appsincluding components of WSL (Windows Subsystem for Linux), which further complicated matters. The most effective solution, again, was to uninstall the conflicting update.
Reasons why you can't upgrade to Windows 11
Although normally the jump between versions of Windows 11 should be almost automatic, there are times when The update refuses to appear or it does not finish correctly despite trying several times.
Hardware that does not meet the minimum requirements
One of the main reasons is that The hardware does not meet Microsoft's minimum specificationsThe basic requirements for Windows 11 include:
- Supported processor (relatively modern models, according to Microsoft's list).
- At least 4 GB of RAM.
- At least 64 GB of available storage to install and update.
- Graphics card compatible with DirectX 12 or later, with WDDM 2.0 controller.
- TPM 2.0 chip enabledwhich many motherboards have but is sometimes disabled in the BIOS.
If your device has TPM 2.0 but it is disabled, you will need to Entering the BIOS/UEFI on startup and enable the corresponding option (sometimes called TPM, fTPM, PTT, etc.). Without this, Windows 11 may refuse to install or update.
License messages and “weird” Windows editions
In some cases, the chaos with updates is accompanied by messages about the Windows edition or licenseFor example, upgrading from Windows 10/11 Home to Pro with a dubious key or taking your computer to a store where they "upgrade" it for a fixed price can result in an edition that doesn't correspond to your actual license.
It is quite frequent that Unscrupulous technicians install Windows 11 Pro In consumer devices, the default was Home. Pro is designed for businesses and manages licenses differently.
If your edition does not match the digital license associated with the hardware, Activation errors and end-of-service notices may appear. or unusual behavior in Windows Update. It's a good idea to check in Settings > System > About which edition you have exactly.
How to fix update problems in Windows 11?
If your goal is to upgrade from an older version (or Windows 11 SE) to continue receiving supportBut if the updates fail, you can try several approaches, from the gentlest to the most drastic.
Option 1: Use the Windows Update troubleshooter
Windows 11 includes a specific tool for Automatically detect and repair update errors. To use it:
- Go to “Start > Settings > System > Troubleshooting > Other troubleshooters”.
- In the "Most frequent" section, click on "Windows Update > Run".
- Wait until it finishes and, when it indicates, restart the computer to apply the changes.
With a bit of luck, this will be enough to unlock stuck updates or corrupted packages without having to touch anything else.
Option 2: Clear the SoftwareDistribution cache
If the problem originates from the Windows Update cache, the most effective method is usually to empty the contents of the SoftwareDistribution folder (but without deleting the folder itself) after stopping the services involved.
In the “Services” window, you must Stop “Windows Update” and the “Background Intelligent Transfer Service” (BITS). While these services are active, some cache files may be in use and cannot be deleted.
Next, access C:\Windows\SoftwareDistribution and remove everything insideThe next time Windows attempts to update, it will recreate the necessary files from scratch.
Once you have deleted the content, return to the Services window and Start Windows Update and BITS again so that the system can search for updates normally.
Option 3: Uninstall a conflicting update
If your problem was triggered after a specific patch (such as KB5051987 or KB5050009), the most logical thing to do is to revert that update.
- Go to “Settings > Update & Security > Windows Update”.
- Go to “Update History” and tap “Uninstall updates”.
- Locate the problematic update by its KB code and delete it.
- Restart your computer and check if the problems (browser, Bluetooth, camera, etc.) disappear.
Then you can temporarily pause updates to prevent the same patch from being reinstalled immediately.
Option 4: Restore the system to a previous point
If you had the System protection and restore pointsPerhaps you can return to a state where everything worked.
- Click Start and type “restore point”; then choose “Create restore point”.
- On the “System Protection” tab, click on “System Restore”.
- Select a restore point prior to the problematic update.
- Confirm, press “Next” and then “Finish”. The computer will restart and will revert to that previous configuration.
This process usually keeps your personal files and many settingsbut it reverses changes to the system and some applications.
Option 5: Repair Windows Update with external tools
When problems persist, a specific utility like the Windows Update Reset tool, a free and open-source program.
- Download it from its official website and extract it to your hard drive.
- Run “wureset.exe” as administrator.
- Choose your language and select “Restore Windows Update components”.
- Wait until it finishes; it should be done in a few minutes. rebuild the Windows Update infrastructure and leave it as new.
This can be especially helpful when There are errors in internal components of Windows Update. that are not fixed with the standard solver.
Option 6: Use the DISM, SFC, and CHKDSK commands
To repair damaged system files, it is advisable to use PowerShell or the command prompt with administrator privileges and, if appropriate, make a copy of the record.
- Open PowerShell as administrator (search for “powershell”, right-click, “Run as administrator”).
- Execute these commands one by one, pressing Enter after each one and waiting for it to finish:
- DISM.exe / Online / Cleanup-image / Scanhealth
- DISM.exe / Online / Cleanup-image / RestoreHealth
- sfc / scannow
- chkdsk /scan
- chkdsk c: / f / r
After executing Running sfc /scannow is recommended; restarting is recommended. Before proceeding with the rest. These commands analyze and repair system files, the Windows image, and potential disk errors that may be interfering with updates.
Option 7: Upgrade in place using the Windows 11 ISO
If Windows Update simply won't work, a very effective alternative is Perform an in-place upgrade using the official Windows 11 ISO imageIt's not a clean reinstall, but a kind of "repair/update" that keeps your personal files, programs, and most settings.
- Go to the official Windows 11 download page on Microsoft and download the ISO or the installation wizard.
- When the download is complete, disconnect from the internet and disconnect all external devices except the keyboard and mouse.
- Temporarily disable any third-party antivirus software you may have.
- In File Explorer, double-click the ISO to mount it and run “Setup.exe”.
- Follow the wizard by choosing to keep files and applications, and let it complete the update.
This process usually repair damaged system registers and components And, in addition, it leaves you with the latest available version or a much more recent one than the one you had.
Option 8: Reinstall Windows from scratch
When you've tried everything and the system is still a mess, consider a clean reinstallation This may be the most sensible thing to do, especially if you need a stable and up-to-date environment to work in.
Yes, make sure before you have a backup Back up your documents, photos, passwords, important settings, and any other data you don't want to lose. Once you've created the backup, you can use the official Microsoft tool to create a Windows 11 installation USB drive and boot from it to format and perform a clean installation.
What to do if the latest updates don't appear?
It can happen that, even knowing that a new version of Windows 11 exists, Don't see it in Windows UpdateIn that case, check the simplest things first.
Check if updates are paused
Sometimes, without realizing it, We have paused updates weeks ago. To verify:
- Go to “Settings > Windows Update”.
- Check if the "Pause updates" option is enabled. If it is, disable it.
- Press “Check for updates” to force a new check.
Restart to clear temporary files
It sounds like a cliché, but Restarting your PC helps clear temporary files and unfreeze unfrozen processes. that may prevent the application of patches or changes to the system.
When Windows computers are turned off and on, They remove a large portion of the corrupted temporary files which can block an update. If you haven't completely shut down your computer for several days, give it a break and try again.
When Windows 11 SE or an older version of Windows 11 reaches its end of supportThe important thing is not to get stuck in time: it's best to switch to a maintained version as soon as possible, check that the hardware and license are up to date, and if Windows Update gets complicated, use the tools offered by the system itself (troubleshooter, cache cleaning, restore points, repair commands) or more advanced methods such as in-place upgrade with ISO or clean reinstallation; with a little method and patience, it's perfectly possible to keep your PC up to date and well protected so you can continue using it with peace of mind.
