How do you prevent non-admin users from installing a game on a computer? A game like Steam would require the password because it installs it on all users, but a game like Roblox would not need a password because it installs it only on a specific user. How would I block games like Roblox from installing?

Note: I have an admin account.

    Probably create a startup script deleting the %AppData% folder? Mar 3, 2018 at 14:41

Via local group policy:

Block users from installing or running programs in Windows 10/8/7


Type gpedit.msc in start search and hit Enter to open the Group Policy Editor. Navigate to Computer Configurations > Administrative Templates

Windows Components > Windows Installer. In RHS pane double-click on Disable Windows Installer. Configure the option as required.

This setting can prevent users from installing software on their systems or permit users to install only those programs offered by a system administrator. If you enable this setting, you can use the options in the Disable Windows Installer box to establish an installation setting.

The “Never” option indicates Windows Installer is fully enabled. Users can install and upgrade software. This is the default behavior for Windows Installer on Windows 2000 Professional, Windows XP Professional, and Windows Vista when the policy is not configured.

The “For non-managed apps only” option permits users to install only those programs that a system administrator assigns (offers on the desktop) or publishes (adds them to Add or Remove Programs). This is the default behavior of Windows Installer on Windows Server 2003 family when the policy is not configured.

The “Always” option indicates that Windows Installer is disabled.

Edit: this blocks programs installed via the Windows Installer. I am unaware of a way to block software installation outside of locking down the Windows Installer.

    Does this prevent installation of programs that don't use Windows installer? Jan 23, 2018 at 1:37
  • @TwistyImpersonator Nothing can do that, unless you block all applications, except those on a whitelist

  • @Ramhound Yes, and by not mentioning that, this answer creates the impression all installations are blocked. Jan 23, 2018 at 1:51
  • I agree with Ramhound, I am unaware of any native configuration that will prevent it. Other than locking down common installation folders and blocking specific file types. But that could introduce other issues and be difficult to manage. Jan 23, 2018 at 1:52

    @Ramhound What? "You can access Roblox on PC, Mac, iOS, Android, Amazon Devices, and Xbox One. Roblox adventures are accessible from any device, so players can imagine with their friends regardless of where they are."
