    I followed "Method 1: How to Prevent Specific Users from Accessing a Drive or Folder" to prevent access to guest accounts. Unfortunately, now I am not able to access all those drives and files from the admin account for myself. Please help me in this regard, I reversed all things and gave access back to the guest account and everything but still, it is not working. Even though I have deleted all those guests' accounts, still there is the same issue. Looking forward to hearing back from you soon. Thank you

      First of all, when making changes to privileges you should be careful and follow the instructions exactly.
      To fix the problem: 1. Enable the hidden "admininstrator" account by giving the command: "net user administrator /active:yes" (without quotes) in admin command prompt. 2. Then, restart the PC and login with the "Administrator account" 3. Revert back the changes you made and give yourself access to drives/folders.
