In windows 10 bulid 10586.164 (stable version) I can't access the start-menu or I can't open the search bar. Could someone help me how to solve this problem?
The installation is an upgrade from windows 7 to windows 10. The start menu has worked before, for now it doesn't work. As far as I know are all updates installed, but I will check once more tomorrow. Thanks for your help.
Today I have tried to restart the computer but I have got still the same problem. Is there another way how I could solve this? Or is the only way to use an installation disk to restore the system?
Sorry to hear that leaving the system alone and reboot did not help.
Go to All Settings > Update > System Restore, there is an option to completely reinstall W10. The sources are downloaded to your PC; you don't need an installation disk.
You could also try do a repair install of Windows 10 by performing an in-place upgrade without losing anything other than all the windows up dates . You will need the Media Creation Tool for that!
