If you are deploying Windows 7 Enterprise but don't want users to be able to install and use Windows XP Mode on their comptuers, you can do one of the following to block this:
- Make the users Standard Users instead of local admins on their computers so they won't be able to install programs on them.
- Use AppLocker to create a Deny rule for the Windows Virtual PC executable (vmwindows.exe).
- Use the Compatibility Administrator in the Application Compatibility Toolkit (ACT) to create a custom APPHELP HARDBLOCK to prevent XP Mode from installing.
- Disable hardware virtualization on users' computers and lock the BIOS on their computers with a password, then block access to sites where they can download the hardware-assisted virtualization emulation hotfix.
