Windows 11 not updating to Windows 11 Insider Preview Feature Update (26220.7051)
Respected Madams/Sirs, I am facing a very unexpected problem while updating to Windows 11 Insider Preview Feature Update (26220.7051), which encounters an error and says, "couldn't extend system reserved partition". My disk has a lot of free space available, but the EFI, of course, was full with 6mb left, so I had to extend its capacity. To fix this, I tried numerous methods, but they eventually proved fruitless. Tried extending the EFI size (currently 100 MB) using GParted, but couldn't, so created a new EFI with a 500 MB size. Executed the necessary steps and commands to make sure the computer used the new EFI as its primary EFI. The computer boots using the new EFI, but the update error hasn't gone. Tried clearing unnecessary files from the original EFI. Nothing worked. Tried cleaning my hard disk, which of course might not be the key for this since the error is related to EFI, not the hard disk itself. Still, nothing worked. To put it short, I may have tried every method possible, but nothing has worked. I urgently require assistance. My current Windows version is Windows 11 Home, version 24H2, OS build is 26120.6982, on a Dell Inspiron Laptop Please help. Thanks!
Windows 11 25H2 – Update KB506881 causes unexpected reboots (no BSOD, silent restart)
Hey everyone, just wanted to report a serious issue I encountered with Windows 11 25H2 related to the update KB506881. After installing KB506881 my PC randomly rebooted without warning — no BSOD, no crash report, no error on screen. Only the event log showed “unexpected shutdown / Kernel-Power (Event ID 41)”. Removing the update completely solved the issue. Since uninstalling it, my system has been 100% stable with zero unexpected restarts. Reproducibility: Install KB506881 → system performs unexpected shutdowns / reboots Uninstall KB506881 → issue disappears immediately System details: Windows 11 25H2 (Build: 26200) AMD Ryzen 7800X3D (but issue seems unrelated to hardware) No BSOD / no memory dump / no bugcheck created Reliability Monitor only shows “Unexpected Shutdown” What I already did: Removed KB506881 manually → issue gone Blocked the update using PowerShell + scheduled task (hourly) to prevent Windows from reinstalling it Logs: Event Viewer → Windows Logs → System Shows: Kernel-Power 41 (unexpected shutdown) immediately after KB506881 installation. Has anyone else experienced unexpected reboots after KB506881? If yes, please comment so Microsoft can see how widespread this is. I also reported it via Microsoft Feedback Hub.

Unable to install the Windows Preview Update

I have retried around 5 or 6 times and still same error persists, It shows the following error. Windows 11 Insider Preview Quality Update (26220.7872) Install error - 0x80070306 Please help me fix this issue, Thank you.
Wanted to join Beta Channel, ended up forced to upgrade to Windows 11 Insider Preview, how to stop?
So, it all started with me wanting to join the Beta Channel for Excel since I wanted to have the new features available there. So, in Excel I couldn't find the Insider Button at Account menu even though I am a MS365 Subscriber. So, I thought I had to go to Windows Settings -> Update & Security -> Windows Insider Programme to use it. After I registered there, instead of showing me in Excel Beta Channel it now is downloading and installing Windows 11 Insider Preview, what I don't want and theoretically shouldn't be able to get since my processor is too bad, it tells me that in the same window at the right side. (I am currently on Windows 10 Home 22H2-19045.3324) I have already tried to leave the program and i am getting different response to that, the Windows Insider Programme in the settings tells me that I am still set to get Insider Preview builds and the Windows Update menu also. But when I click on Leave the Insider Programme in Windows Insider Programme it directs me to a page which says This email address is not registered as a Windows Insider.... And yes it's the same E-Mail address that's linked to the program and which was connected to the page that told me the E-Mail address is not registered. Also, Sidenote: Many buttons are not responding at all, clicking on fix the problem (see image) doesn't work, before that, changing Channels, adding E-Mail all did not work first time. And In Office clicking on Join MS365 Insider doesn't do anything either. This whole program seems verry unstable. My questions are: 1. How to undo all that so I don't must upgrade to Windows 11 Insider Preview 2. How to join Office Beta Channel the correct way?I was told by a Microsoft assistant to come here for help regarding an insider update issue.
As the title reads, a Microsoft assistant told me to consult this community regarding the issue I am facing now. A while ago, I foolishly did not read the fine print and opted into the dev channel of the insider program, because I was having difficulty installing Windows 11. I later found out to my horror that, I could not opt out until a particular window was announced. I have been waiting since then, and updating my computer in hopes that one of these updates will allow me to swap back to the beta channel, and then, hopefully to a stable version of Windows. When I attempted to update today to the "Cumulative Update for Windows 11 Insider Preview (10.0.26120.2705) (KB5050636)", I received the "Install error - 0x800f081f" message, and all the results I have searched have so far given me nothing but pieces of advice that make me fearful for the safety of my computer data. Is there anything I can do that will not run the risk of data deletion, or is it hopeless? I feel like I've run down every alley here. Thank you.
