.NET framework 3.5 error 0x800F0922

[DanFosing]

When trying to install .NET framework 3.5 i am getting error 0x800F0922 on newest windows insider dev build. Using DISM in terminal with administrator rights gaves same error.

Hello @DanFosing,

To fix error code 0x800F0922, try this:

1. Open administrative Command Prompt.
2. Run lodctr /R command.
3. Once executed successfully, execute winmgmt.exe /RESYNCPERF command.
4. Retry installing .NET Framework 3.5.

If this doesn't works, try other suggestions mentioned in this fix:
