Disallow Windows User Accounts Installing Software

Locking Down Windows User Accounts
InstallGuard will disallow users installs.
 (Get it from a 3rd party site. The developer
 site has some odd stuff going on. It is free.
 To uninstall you must go into file-exit first.)
You can white list the admin account.

 RollBackRX (free) will easily allow returning
 system to previous state.

I am trying both of these currently so work in progress.

File Priority Saver

I may try Prio for bypassing the security prompt on portable programs I run. For instance, I use Everything search a lot. I have unsuccessfully tried bypass security through manual settings. I don't like that Prio installs and don't know the resources it takes yet.

I tried this but the UAC bypass remained grey and unusable. Not instruction could be found.
