Select Settings > Accounts > Sync your settings. If you see a message at the top that states You are logged on with a temporary profile. Roaming options are currently unavailable, restart your PC and sign in again. This should remove the temporary account and your files should be available again.
Restarting your PC and signing in again also works if you see a message that states We can't sign into your account. This problem can often be fixed by signing out of your account and then signing back in.
You might need to restart your PC more than once before you can see your files again.
You should back up everything you worked on since upgrading to an external drive, or it'll be deleted when you sign out of the temporary account.
Select the search box on the taskbar and search for your files. If you don’t see them and you’re not signed in with a temporary profile, use the troubleshooter to fix problems with Search. In the search box on the taskbar, type indexing, and then select Indexing Options. Select the Advanced
button to view more options, then select the Troubleshoot search and indexing link and follow the steps.
Some files might be hidden from view. In the search box, enter Show hidden files and folders. Under Hidden files and folders, select Show hidden files, folders, and drives. Then try searching for your files again.
Look for all files of a certain type using the asterisk (*). For example, to search for all Word documents, search for *.doc. For music files, search for *.mp3.
When you upgraded to Windows 10, some of your files may have been moved. To check the location of files you find, right-click the file and select Open file location. Copy any files you want to move to a different location.
In the search box, type Backup and restore. Open Backup and Restore,and then select Restore my files. Follow the instructions to restore your files.
Sometimes you can recover a file by creating a new one with the same name and file type. After you’ve created the new file, select Properties, select the Previous Versions tab, and then choose the file version to restore.
If you created a new Microsoft account when you upgraded from Windows 7, your files may be located in a disabled administrator account. You'll need to enable this account and sign in again to see your files.
In the search box, type computer management and then select the Computer management app.
In the left pane, select Local Users and Groups, and then select Users. If the user named Administrator has a down arrow on its icon
, it’s been disabled.
To enable this account, double-click the Administrator icon
to open the Properties dialog box. Next, clear the Account is disabled check box, and then select Apply to enable the account.
Sign out and then sign in again using the Administrator account.
