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. Thanks!
Unable to install release after windows 11 insider.
I was a Dev insider since windows 11 insider was a thing and I want to switch to the Release build now as some of the applications I use aren't working well with the insider ones. Unfortunately my pc wont show me the update and Windows 11 Installation Assistant Wont open (it closes almost instantly) and I cant seem to be able to get out of insider using the windows update without the need to format... Also booting to a USB with the ISO for windows 11 wont also allow me to keep my files.
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?Announcing Windows 10 Insider Preview Build 19608
