Someone from another computer added themselves as administrator to my computer and is causing problems. I cannot delete them from that administrator setting until I turn off the inheriting permissions setting. How do I find and turn off the inherited

How to disable inherited permissions on a folder by default?

When I create a folder "foo" under the C: drive, I then run

icacls "C:\foo" /inheritance:d

to remove permission inheritance on it. But if I create a folder under foo like C:\foo\bar, bar still gets the inherited permissions Users added to it and it can't be removed without 1st running icacls /inheritance:d on it as well. Is there some way to disable
the inherited permissions by default instead of having to run this command all the time?

 

HOW DO I GET PERMISSION TO DELETE FILES

You can try the following steps to change the file permissions, after which you may be able to remove the desired file from your computer. So, learn it completely before applying.

1. At first, right-click on the file and then select the Properties option under the list.
2. Next, navigate to the Security tab and then click on the Advanced button.
3. Further, click on the Change Permissions button that is there at the left-hand side corner.
4. In the next window enable the checkbox for "Replace all child object permissions with inheritable permissions from this object" and disable the checkbox for "Include inheritable permissions from this object’s parent". This will pop-up a window, click on
   Add.
5. After that, check if you see any permissions with Deny in the Type. If you find any, then remove those first.
6. Next, enter your user name and the Administrators group by clicking on Add.
