Over the Thanksgiving weekend, I upgraded one of my computers from Windows 7 to Windows 10 using Windows Update. It had been nagging me to upgrade for awhile and I finally gave in and did it. The upgrade appeared to go smoothly, but when I logged on to Windows 10 for the first time, I realized that I didn’t have any of my settings or files. I checked the Application event log and sure enough, I was logged in with a TEMP profile.
I Googled this a bit, thinking that perhaps it has happened to a few other people who could point me to a quick resolution, but it didn’t seem to be a common problem. Also, the proposed fixes (like running
sfc /scannow didn’t strike me as being very promising.
So I open the Local Users and Groups manager (lusrmgr.msc) and checked the group membership of my account. I found that it was a member of the Administrators group and a HomeUsers group, but not a member of the Users group. I checked a Windows 10 computer that I had built from the 10240 build ISO as a clean install and didn’t find a HomeUsers group at all. Back on the problem computer, I added my broken account to the Users group, restarted, and logged in. This time, Windows took my account through the typical first-run setup stuff and then loaded the correct profile, with all of my settings and files from Windows 7 intact.
So, if you run into the problem where an account on a recently upgraded Windows 10 computer is missing settings and files, check the group membership. If the account is not a member of the Users group, you will not be able to log in properly. Add the account to that group, logout and then log back in. Your problem should be fixed
