A couple of things to try and see if they work for you would be AccessChk - it's one of the sysinternal tools:
AccessChk v6.12

Powershell  and the Get-Acl cmdlet. Something like:
Get-ChildItem C: | Get-Acl
Would just go through the top level of the drive. You would add -recurse to get all subdirectorys on down:
Get-ChildItem C: -recurse | Get-Acl

There are likely others options you can use. Those are the ones I've used
