Hi all,
I've broken my grant of disk C: (Operative system disk) of my PC. Now after remove the "Full control" to Administrator user on C: --> Proprieties --> Security I cannot longer restore it with any kind of user. I need then to restore back the "Full control" on the root C: disk and related subfolders under Security to Administrator user.
 
Unless you have another administrator account you will need to re-install Windows. If you want to make sure that you don't lose any files, you can install Windows on another hard drive, install the original one as a secondary and copy your files to the new build from it.
 


If you can take ownership of the files again you may be able to get around the fact that you removed rights, if it will let you. Aside from that, backup your files and do a clean setup, and don't mess with files or settings unless you know exactly what the results will be.
