How Did I Solve the ERROR CODE 0x800f0922

Recently, Microsoft released the new patch KB4551762. I hit the check for update as usual and wait for rebooting, however this time I met with a problem and WINDOWS cannot finish the update but undo the changes.

After its rolling back, i saw the error code 0x800f0922 

First of all, I want to make myself clear that 0x800f0922 is just a general error code that returned by the installing process, and many factors can lead to that, my solution may not fit your situation but I hope I can give you some suggestions.

Windows have a comprehensive log system, and we can find even anything about the operations the system have done during the updating process.

Navgiate to the folder C:\WINDOWS\Logs\CBS and you will see the log named CBS. Open it with notepad, and you will see many many info, and it should start with

2020-03-25 23:12:37, Info     CBS    TI: --- Initializing Trusted Installer ---

2020-03-25 23:12:37, Info     CBS    TI: Last boot time: 2020-03-25 22:55:36.500

2020-03-25 23:12:37, Info     CBS    Starting TrustedInstaller initialization.

Ctrl+F and search for the error code 0x800f0922

2020-03-25 23:45:58, Info     CSI    000009e2 ==Error Summary Start==

2020-03-25 23:45:58, Info     CBS    Setting ExecuteState key to: CbsExecuteStateInitiateRollback | CbsExecuteStateFlagAdvancedInstallersFailed

Pay attention to the line between Error Summary, and i can see there seems to be something wrong when Task Scheduler was been insatlling.

So I trace back to see what's wrong with the Task Scheduler.

And what I see?

2020-03-25 23:45:58, Error      [0x018003] CSI    000009a3 (F) Failed execution of queue item Installer: Task Scheduler ({386b5911-b69e-4d2d-a3ab-796d2ec6af38}) with HRESULT HRESULT_FROM_WIN32(ERROR_ACCESS_DENIED).  Failure will not be ignored: A rollback will be initiated after all the operations in the installer queue are completed; installer is reliable[gle=0x80004005]

I think i have found the key problems that prevent a successful updating.

So I googled for it and I found it was not a new bug instead it have been observed for a long time since about 1809. The error occurred in Tskmgr which was actually to be blame for the XblGame, a registry was not correctly configured and the update installer failed to access to it, so it failed. : (

Once i knew what's wrong with my laptop, the fix process will be easy.

Clean up the realated temp files, just navigate to C:\Windows\System32\Tasks\Microsoft\ and delete the XblGameSave(whole folder).

and I open up the regedit and navigate to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Schedule\TaskCache\Tree\Microsoft\XblGameSave

JUST delete the whole XblGameSave.

Exit the regedit and check for update again.

This time all of things worked smoothly and I finally solved the Problem.
