How to copy windows.old folder to another drive?

Solution 1:

I need to set the proper permission for this action

Your new Windows Admin account has a different SSID to the old Windows Admin account.

You need to take ownership of the files/directories on the hard drive.

Note:

• Do not take ownership of C:\. Doing so, could result in Windows becoming very unstable.

Take Ownership of an Object using TAKEOWN Command

This command will take ownership of the folder or drive, and all files and subfolders in the folder or drive.

Open an elevated command prompt.

To grant ownership to currently logged on user:

takeown /F "full path of folder or drive" /R /D Y

To grant ownership to the administrators group:

takeown /F "full path of folder or drive" /A /R /D Y

Example:

takeown /F "C:\windows.old" /A /R /D Y
