Windows 10 My Windows 10 Star Menu and Cortana are not working

I think I found a fix for this, I noticed that on other accounts on my PC that the Windows button and Cortana were working just fine, so I made a new account and tested it and they both worked, I then cut all the files in my Documents and put it on a folder titled Documents into another folder I simply named BACKUPS, I did this for Pictures, Music, Videos, Downloads, and Desktop.I couldn't get the file sharing between users to work so I just put the BACKUPS folder in my Local Disk C. When I logged into the new account, all my installed programs were there (Except for ones that I specifically installed on one account). The BACKUPS folder was still in the Local Disk so I just sent it to my desktop and started putting my old Documents, Music, Pictures, etc, into my new folders. After I transferred all the files I wanted/needed, I deleted my old account. Its been working fine for now, I hope this helps in some way, ill try and help you the best I can.
