Question problem with "user profiles" in Windows 7 Pro 64-bit


Aug 15, 2014
I installed Windows 10 Pro 64-bit as the second of a dual operating system. In the process of doing that I screwed-up the user profile aspect of W7. When I login, W7 loads a Default User Profile (which is not the Default User Profile shown under Users) and alerts me to contact the administrator. I have run SFC /SCANNNOW and error checking.

I've discovered that if I select "edit credentials", Windows Explorer crashes and restarts. Having restarted the Default User Profile issue is resolved to show the Default User Profile listed under Users but its doesn't stick. I have to go through this process each time I login. Below are the two logged errors.
