Question: I’ve found plenty of posts talking about whether you can or cannot or should or should not delete or modify the contents of the /windows/winsxs folder. ?However I have a new installation of windows on a new drive and I’m unable to delete these files from the old drive. ?I get ‘Access is denied’.

How could I go about deleting these, or any other, files on the old drive?

Please note that I do not wish to reformat the drive at this time. ?I’d like to only remove certain data to free up space.

Answer: Take Ownership

Right click on winsxs folder, Properties -> Security tab -> Advanced -> Owner tab -> Edit -> ?select your username, check ‘Replace owner on subcontainers and objects’ -> OK

Add Permissions

Right click on winsxs folder, Properties -> Security tab -> Edit -> select or add your user name -> check Full Control under Permissions -> OK

Propagate Permissions

Right click on winsxs folder, Properties -> Security tab -> Advanced -> Change Permissions -> check ‘Include inheritable…’ and ‘Replace all child…’ checkboxes ?-> OK

The folder is under your control now, so you can delete it and its content.
