Disk sizes are showing incorrect & Illogical in Windows server 2008 r2

Symptoms:  You will observe that in disk management everything looks ok but when you see my computer it reflects incorrect disk sizes.

Also when you login with local admin, then also it works fine.

Resolution:

    Log on to the system by using an administrative user account other than the user account that is experiencing the problem.

    Back up all data in the current user's profile folder if the profile folder still exists, and then delete the profile folder. By default, the profile resides in the following location:

    %SystemDrive%\Users\UserName

    Click Start, type regedit in the Start Search box, and then press ENTER.

    User Account Control permission If you are prompted for an administrator password or for confirmation, type your password, or click Continue.

    Locate the following registry subkey:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

    Under the ProfileList subkey, delete the subkey that is named SID.bak.

    Note SID is a placeholder for the security identifier (SID) of the user account that is experiencing the problem. The SID.bak subkey should contain a ProfileImagePath registry entry that points to the original profile folder of the user account that is experiencing the problem.

    Exit Registry Editor.

    Log off the system.

    Log on to the system again.

Take a reboot after clearing the .bak profile.
