That you want to be rid of that particular file/folder, make a Linux Live CD and boot to that OS. It will not make any changes to the files until you tell it to do so. Just be care that is all you delete. Then reboot to the Windows OS and check to see if it gone.
When Windows will not allow what you think you should be able to do, Linux Live can be of value for other tasks, too.
Checking disk I discovered a folder c:\Users\...\Temp\imgMnt01 with size 10Gb, see here:

It looks like the image of an entire disk Win7+C:, probably in conjunction with NTlite, I used a long time ago.
I suppose, if the Temp directory is not needed for running os.
But it is not delete in any way: no programs like Unlocker, or MoveOnBoot, etc. Even in safe mode.
I have admin rights, I am the only one on this PC.
What to do? I cannot find any procedure, consult someone with a similar experience?
Thanks for the advice
