So my metro applications stopped working, including start button and notifications button. When i try to open one it shows on second then it closes itself. I checked event viewer, and there were a lot of errors, they always appear when i try to open an application. Example when I press start button:
Activation of the app Microsoft.Windows.ShellExperienceHost_cw5n1h2txyewy!App for the Windows.Launch contract failed with error: The app didn't start..
I know what might have caused this error, i done a stupid thing and i used a program Unlocker 1.9.2 and i unlocked Windows folder (That program is used when you want to unlock a file to delete it ) So i don't know what problems i made, is reinstalling windows only solution?
