  1. Revert SystemData folder permissions


    Can someone please help me revert the SystemData folder permissions to default ones?

    C:\ProgramData\Microsoft\Windows\SystemData

    I took ownership of the folder and removed certain principals afterwards because I was not sure they were there by default. While removing them some errors popped up.

    I attached a screenshot of the current state.

    Does anyone at least know how should the default state look like? Who are the default principals?

    Thanks.

    :)

    SystemData folder, Can't set this one as lock screen image

    The issue still persists even after creating a new admin account. I only deleted the SystemData folder following steps to fix the grey loading screen problem from this post.
    However the SystemData folder did not recreate istelf and the registry key did not re-populate.

  4. Revert SystemData folder permissions

    Understanding 'Access Denied' so that permissions can be reverted - icacls and takeown

    • Before taking ownership of files and folders I would like to understand how to view the current permissions so that they may be reverted.
    • I am reciving an 'Access Denied' message to view or save permissions with elevated command prompt for location: C:\ProgramData\Microsoft\Windows\SystemData in Windows 10 enviroment.
    • It looks like that I may need to take ownership first, then can view the permissions, and use something like icacls 'reset' command to fix it afterwards.

    If I try to view permissions:

    If I try to save an ACL file:

    In the answer to 'Understanding how to use Icals & Takeown' the owner of the folder was NT SERVICE\TrustedInstaller which may infact may be a standard in Windows 10, though I am only guessing.

    Should I just use takeown, and icals, find out the permissions and then use the reset command.

    Likewise with the ACL, one would need to take ownership before creating, or is there a work around?
