Credential Manager in Windows 10

I am running Windows 10 Pro with latest update on my Laptop.  I have WD MyCloud 3TB NAS.  Users and shares are setup and all was working until recently.  My partner has the same OS on his laptop with mapped drive and all works just fine even after reboot.  Somehow, whenever I map the drive, it works.  But upon reboot, it shows red X next to the mapped drive with no error message.  I had done extensive research and finally concluded that my Credential Manager is somehow not retaining my credentials that I enter when I map the shares.  On every reboot, I lose the credentials and therefore I cannot access mapped drives.  I am not using any scripts.  Just simple windows map network drive option.  It used to work just fine on my Windows 8.  In fact it did work fine on Windows 10 initially but now it does not work.

All firmware has been update on NAS.  NAS has been rebooted several times.  In fact, NAS has been refreshed.  I had already spoken to Western Digital tech support and even they mentioned that something is removing your credentials from Credential Manager in Windows.  They are puzzled too.

So if anyone can guide me to resolve this issue, it will be much appreciated.  Thanks

I am looking at Credential Manager on my own Windows 10 machine and all seems to be there (Servers and Workgroup).

Try running System File Checker.
Open cmd.exe with Run as Administrator and run SFC /SCANNOW.
Allow to complete, restart or, preferably, shut down the computer and then start up again.
Test to see if the problem has been corrected.

Does this help?  If no, try DISM.
Open cmd.exe with Run as Administrator.
DISM.exe /Online /Cleanup-Image /Scanhealth (takes 15 - 20 minutes).
DISM.exe /Online /Cleanup-Image /Restorehealth (takes 15 - 20 minutes).
Restart the computer and test.

If you continue to have difficulty, what operating system did you upgrade from? And, are you at the current build of Windows 10 (Version 1511 Build 10586.122)?

Actually, after looking at an app that does housekeeping, seems to have been housekeeping Windows Credential Manager.  After I disabled it, Credential Manager seems to work just fine without applying your suggestions above.

Thanks anyways
