How to remove a screensaver on Windows 10Įunice 3 years ago Windows 10 圆4, Google Chrome.Any help would be appreciated! Linked pages I've tried everything to change the permission but I've had no luck. I require permission from TrustedInstaller to make changes to this file. a window pops up saying denied - I need permission to perform this action. I tried through the apps, and manually through the system files but when I right click to delete. Hi, I followed all the steps listed to uninstall the old file.
