Since last week, my laptop stopped functioning correctly. the windows key does not work, windows button on the bottom left corner does not respond, cannot open Start, cannot go to internet access menu, black icons in desktop, cannot install programs (file system error 65535), cannot open things like action center, control panel, etc.
I can see the same problems in safe mode except installing programs, so I assume it is Windows problem?
I have temporarily fixed the black icons by using icon packager and changing the theme of the icons.
I have scanned for virus using Kaspersky, no threat found.
I have used safe mode to install ccleaner, ran everything there.
I have refreshed explorer.exe many times.
I have used restore point, but failed to complete the restore.
I have done system scan using sfc /scannow, nothing.
I have tried most of the things on Google, but nothing seemed to work.
Is there a way to fix one/all of the problems?
