I have upgraded my Windows 7 to Windows 10 (final) just 2 days ago.
As I can see, all the files for Win7 are now located under C:\windows.old folder. That's great of course, but now I want to backup this folder on another HDD I have in this PC.
When I'm trying to copy this entire folder to drive E for example, I get an error message that I need to set the proper permission for this action.
As far as I can see, the current user is part of the Administrators group and should have full access to everything. That's the way it was originally on Win7 before the upgrade and I expected it to remain this way also after this upgrade.
Why am I getting this weird error message and how can I perform the action I need, as described here?
