For some unknown reason my Windows 10 Start menu will not open and right click on programs on the task bar do not respond either. Doubleclicking on shortcuts indicates "do I want to run" and I select YES and the program disappears and is not showing in the Task manager either. Whenever I reboot it takes a very long time to get started again and that has not been the case before this problem reared it ugly head.
When it is up it appears normal otherwise and I can run some programs without any diffculty as I am doing with the Firefox posting this on the Internet. In some cases when I can't get the program to run from the shortcut I can go to the actual program exe file on the C drive and run it with no problem but not all will run that way either.
I have run Tweaking latest version in Safe Mode 3 times but doesn't really appear to be doing anything at all. I have tried all the suggestions I found on the Internet including using the Powershell with "Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}" pasted into it but get the message "denied etc".
So far 2 days of frustration with this as I have not been having any problems with Windows 10 since first installed months ago.
HELP!!! someone.
