Windows 10: How to acquire permission to delete files which are restricted by SYSTEM

I recently found that my system is consuming more than 15GB of extra space without my knowledge. I updated Windows and some Intel graphic drivers. I used a third party app and found this:I have deleted this type of folder multiple times but this time it can't be deleted! It's showing this:Even after I wanted to change its properties, there is no add or remove buttonlease help

File permissions to delete file

I am trying this, but it's taking a very long time.

 

File permissions to delete file

Windows is extremely confusing in its permissions and file ownership.*Sad

If Taking Ownership of the files does not work, then the ACL and permissions are misconfigured.

Permissions precedes the ownership, you can have ownership but incorrect permissions in accordance with the ACL Access Control Lists (Windows).

Microsoft - How Permissions Work

I suggest that you open powershell (Search > type powershell > Right click > run as admin) and execute this command:

Code:

This command restores permissions to default for all files contained within C:\ quietly.

Followed by this command once completed:

Code:

This command restores full permissions to the Administrators on the computer, which I presume you are an Administrator.

And reboot the computer, and finally attempt to delete the file after attempting to retake ownership.

If that does not work, then I suggest using a third party utility known as UnlockIT:
Downloads - UnLock IT

And download, install. Ensure you select customized installation.

Right click the folder that contains the files or the files individually that you would like to delete, and follow as here:






Then this should delete all files you right clicked upon after restarting the system.

You should not run into issues regarding permissions after this, and if you do, post again and I'll look into it.

Side note: often times malware tends to hijack a system and fluff itself in permissions that benefit itself.
