Tools–>Internet Options–>Compatibility View Settings–>someWebsite.com–>Add/Remove Please help with code working with powershell 3.0. Note: It has to be done only via a code working with powerhshell 3.0. September 7, 2016 at 2:00 pm #53740 Don JonesKeymaster What have you already tried to solve this problem? We're happy to help you if you're stuck, but as a community of volunteers, we can't really just do it for you on-demand.

Note that if you don't want the values removable by the user (HKCU), then you will need to set HKLM, which requires elevated privileges on the system.
