Registry Change with MS Update now Unknown Permissions in Security Settings RRS feed

  • Question

  • Good Day, After the most recent Security Update Patch, i noticed that after logging unto my computer, there was Registry data scrolling across my home screen, like changes were being downloaded.  Today i noticed there are Permissions Entry in the Advanced Security with the names:

    S-1-15-3-1024-3424233489-972189580-2057154623-747635277-1604371224-316187997-3786583170-1043257646

    S-1-15-3-1024-2302894289-466761758-1166120688-1039016420-2430351297-4240214049-4028510897-3317428798

    Trusted Installer with "Special" Permission

    Each time i deny Permissions a duplicate is created with Allowed Full Control designation.

    Can anyone help me determine what this ?  Is there a way to remove ? Could a malicious entity invaded my computer ?

    Any truthful assistance, is really appreciated.  I don't have computer experience but something doesn't seem right.

  • Hi

    It's safe to remove any listed "Account Unknown" entries in permissions if you are sure it's for an account that will no longer need permissions for the item. More details you could refer to the following link:

    Account Unknown has full Security permissions on my own User - huh?
