I have been removing some files to clear some space and found that despite being the Admin I am unable to delete them because they are from "TrustedInstaller". When I go into security settings it wont let me change anything to do with it and I can't remove it. I find this incredibly frustrating as I own this computer and expect to be able to control what goes on it.

    Hi Euan,

    I am Sumit, an Independent Advisor and a 3 year Windows Insider MVP here to help.

    Files whose owner is TrustedInstaller means the files are protected by Windows to prevent the accidental breaking of your computer. TrustedInstaller is usually the owner of all system files in C: drive and folders on other drives which are related to the OS, for example WindowsApps directory.

    I am letting you some generic steps to gain space:

    To gain space, follow the steps here:

    First of all, eliminate all useless files on C:/ by using Disk Cleanup.

    Make sure you have checked System files option after the first scan.

    Also,

    Treesize should tell you which files and folders are taking up the space.

    It is worth checking the Users folder and its subfolders with it.

    Please let us know if you need any assistance.
