ntuser.dat files not being backed up and occasional temp profile being created

[silhouett]

Since my last windows update I have developed a strange problem. When I use Tweak backup  I get the following in the log

[2/11/2016 - 12:24:22 PM] Backing Up File: C:\Users\Administrator\ntuser.dat
[2/11/2016 - 12:24:22 PM] Result: Failed - Error: -1 (API Reg Save Failed (), Tried File Copy, File In use, Cannot copy.)

[2/11/2016 - 12:24:22 PM] Backing Up File: C:\Users\cbrid_000\ntuser.dat

I then started to notice if I login as any one of the four account on my system, not consistently but on occasion I am getting a temporary Profile message
and a temp folder is created for that user.  But if I restart and login say again I am fine ?

Any Idea's on what is causing this and how to attempt to fix it.

Do a chkdsk on the drive. The error from the program means the file was in use and it couldnt back them up. If the profiles where loaded at the same time you would get that error when using the fall back method. If using the VSS method you shouldnt get that error.

Windows will create a temporary profile when it is unable to read the user registry file. So if you are getting that then the file is either locked by another program, is corrupted or there is a file system corruption that chkdsk should fix. Of course if it s a bad sector problem then that means the drive needs replaced.
