Windows 10 "Action Center" and "Start" Revive

I finally found my answer and a hypothesis of what I think happened.

What I think happened to my PC

The recurring crash of some unknown reasons, possibly because of the Usrclass.dat because it got corrupted after the crashes and it stopped the future crashing from happening afterwards.

The Usrclass.dat contains important data regarding the metro apps, which surprisingly to me to find out that Start and Action Center are metro apps too

It crashed the coding but no error messages is displayed, but you can find out what happened by runningeventvwr in Run. Then navigate to Windows Logs > Applications in the tree diagram on the left in the Event Viewer. I found out that there are recent errors like:

Activation of app Microsoft.Cortana_8wekyb3d8bbwe!CortanaUI failed with error: This app does not support the contract specified or is not installed. See the Microsoft-Windows-TWinUI/Operational log for additional information.

Looking on Google I found the solution to my problem.

Theme Solution

This solution is from jBurn385http://answers.microsoft.com//message/f5bfbcbc-93d8-448a-98f1-f34d2ccf92ea?threadId=b8b56dd6-1d0b-4920-b883-78f1e6ca28b8

1. Go to Display Settings

2. Apply either one of "High-Contrast" Theme

3. Check to see apps started working and reapply original theme.

Usrclass Solution

*This solution will wipe all the tiles on your Start except for Store, surprisingly.

*This solution will cause the color of the theme to turn black. Re-applying the theme in Personalize will fix that.


  a. Navigate to %LocalAppData%\Microsoft\Windows or

  b. copy that in Run and execute to open File Explorer.

2. Rename Usrclass.dat to something like Usrclass.dat.old

(Create another account and try if file is in use, but make sure the directory is for the original user, something like : "c:/users/chris/appdata/...")

3. Press Ctrl+Alt+Delete and sign out.

4. Sign in again and done.

Powershell Solution

If that didn't work:

1. Create another Admin account. Sign In and Sign Out then Sign In to your own account.

2. Use the command found here: http://superuser.com/questions/844696/metro-apps-on-windows-8-1-crash-on-start#answer-865752
  That is: open Command Prompt with administrator privileges, then paste this and run:

Get-AppxPackage | % { Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppxManifest.xml" -verbose }

3. Seeing that there is no error messages displayed during the program, then retry from 1(You should be using the new admin account by now). Upon finish, you can delete the second Admin account.
