I’ve come across a couple of Windows 10 computers recently where the Start Menu – what you get when you start up the computer – has changed, inexplicably, to something like what you see above. Note on the very left of the picture, little icons with 3 lines at the top and bottom, plus a Power icon. Whereas before you would get a list of all your programs and Apps.
I don’t know why it changed but I have found out how to fix it:
Click the “3 lines” icon top left. “Settings” appears bottom left.
Click Settings, then when the box opens, click “Personalisation” on the right.
Then “Start” on the left.
Then on the right “Use Start Full Screen” – move this to the Off position. Job done.
Another weird Windows 10 quirk! I suspect it might be a virus which caused the issue, so do a virus check as well. I hope this helps you.
