How to fix windows 11 update error 0x800f0991?
Hi everyone, I'm not very good with computer troubleshooting, so I'm feeling a bit stuck. For the past few days, my Windows 11 laptop has been failing to install the latest update. Every time it tries, I get an error code: 0x800f0991. I've tried clicking "Retry" a bunch of times, but it always ends up with the same error message 0x800f0991. I'm worried that if I don't get this update, my computer might have security problems or start acting buggy. Could anyone please walk me through some simple steps to fix windows 11 update error 0x800f0991? Thank you so much for help
Cntl-c/b/s/r/m all non-functioning after Win10-11 upgrade
Cntl (left and right)-c/b/s/r/m are all non-functioning after my upgrade from Windows 10 to Windows 11. I have: upgraded the keyboard driver (they were already the latest) removed the driver and rebooted checked the onscreen keyboard (doesn't work for those keys) uninstalled/disabled MS Game Mode the keyboard is hooked up to a KVM - works properly on the other Win11 system, so it isn't a hardware issue - it's clearly a this-Windows-install issue Moved the keyboard off the KVM directly to the Windows box - same issue Used KeyboardTest V4.0 to check all keys - cntl-c/cntl-b/cntl-s/cntl-r/cntl-m don't show any response stopped all software via taskmanager that I could (of course, many MS ones restarted) enabled cntl-key shortcuts in CMD clipboard manager is disabled (tried both on and off) ran: DISM.exe /Online /Cleanup-image /Checkhealth DISM.exe /Online /Cleanup-image /Scanhealth DISM.exe /Online /Cleanup-image /Restorehealth SFC /ScanNow Any additional help that isn't one of the above items would be appreciated.(Bug #4919194: Unable to add a device to a Microsoft account).
Hello, i have been patienty waiting for about 5 weeks now for this bug to be addressed. I have not been able to register my new pc under accounts.microsoft.com. It is not detected automatically as there is no serial number in BIOS (it says „system serial number“) Registering a device manually with the motherboard’s SN brings up an error. Support has been contacted 4 or 5 times. Have been told each time that its a known bug and i should to try re-registering after 48 hours which in retrospect seems wildly optimistic considering 4 or 5 weeks have now passed. Support ticket number: tel:7091772400 I would appreciate further information / being kept up to date with this issue and hope it can be resolved quickly. regards Timsh67
ISO FILE FOR CREATING WINDOWS RE-INSTALL MEDIA
I have separately posted questions regarding the difficulties in creating a Recovery Drive for Windows 11 - which does not recognise the MANY flash drives, sizes and formats that I have tried. Also tried the Media Creation Tool which was a disaster. So now I'm trying the option of creating an ISO file, which then supposedly will help me create bootable media to recover after a system crash etc. I have FAITHFULLY followed the instructions at https://www.microsoft.com/en-us/software-download/windows11arm64. There is a point where the "save as" in Explorer shows, and the file name shows with the extension of .iso. But when I select save, it saves as Unconfirmed 737311.crdownload, and NOT as the ISO file. I really wish that for once, I could follow the Windows instructions and have them work correctly first time. After about 6 hours of trying to simply create a Recovery Drive or a System Repair Disk, I STILL have neither. This makes me really uncomfortable that I don't have something to get my computer back up and running if it crashes. HELP.¿Cuál es la mejor manera de convertir heic a jpg en Windows 10/11?

Slow Boot - dxgkrnl.sys Not Loading
I know. This has been seen before. I can find the issue all over, but can't seem to find a solution that works for me. This is on a fresh install of Windows 11. It takes about 4 minuets before I can log in, another minuet to get into the desktop, and another minuet before the taskbar loads. At this point I feel like I can start trying to do things, but everything is still VERY slow for several minuets. Windows is up to date I did have a few drivers in device manager that were not found, but that has been taken care of. I honestly don't remember which ones. It's been months. My boot log has dxgkrnl.sys not loading 6 times. It does load before all the failed loads. Don't know if that means anything. WdFilter.sys is also not loaded once. It does also load before not loading. My system log shows; TPM-WMI Service Control Manager OneCore-DeviceAssociationService. I don't think these are part of the issue as my other Windows 11 PC has the same errors present and is quite snappy. I could definitely be wrong here. I have tried running SFC /scannow and Repair-WindowsImage -Online -RestoreHealth in the shell. Both reported no errors. Which is what I would expect on a fresh install. I ran Display Driver Uninstaller then installed Nvidia and Intel drivers manually. Finally I ran Snappy Driver Installer Origin. Nothing has had an affect. My system: ASRock z370 pro4/oem I7-8700K 16GB RAM Nvidia GTX 980-ti Windows is running on a 500GB HDD I know... not an SSD. I have several PCs running Linux and Windows on both HDDs and SSDs. The HDD boot times are noticeably slower, but this one is WAY slower. My next step was going to be a fresh install of Windows 10, then maybe upgrade to 11. After that, replace the motherboard. Hoping to avoid this. Thank you in advance for any help you can provide.
