Windows 10 logged me into a temporary account

There is. You'll need to edit the registry to do so. The path to the profile keys is: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

Basically what you'll notice is the that it's made your main account a backup and the temp account the primary. You'll see this in the name of the profile, it'll end with a .bak. The trick is to switch it around. So you rename the temp to .ba, then on the primary you remove the .bak. Then rename the temp to .bak. This bug has been around for a long time and there are a lot of guides out there on it. There's a caveat on 10 that's new though. You need to set the State key on your profile to 0. Otherwise it'll generate duplicate profiles and you'll have a real mess.

I would caution you to attempt this with caution. It's a registry edit, you can make your system completely unbootable if you make a mistake here. This fix would be done at your own risk.
