I have a newly built W10 machine and I'm having issues when try to copy/paste a file in a Program Files folder or to the Windows folder, just as as examples. Although I'm not the owner of the drive, TrustedInstaller is, I've never had these issues before, especially as a user with both local admin and domain admin credentials. I hate to change the owner to me or some other group since that might affect the OS integrity. When I compare this W10 to another, which also has TrustedInstaller as the owner of the drive, I don't see any apparent differences.

The following is an example of what I get when trying to do a copy paste, and if I say continue it'll say that the source location is unavailable, even though it is. I'm sure it's all related to permissions. Any ideas how to best correct this?
