#################################################
## VMwareCloak.ps1: A script that attempts to hide the VMware Workstation hypervisor from malware by modifying registry keys, killing associated processes, and removing uneeded driver/system files.
## Written and tested on Windows 7 and Windows 10. Should work for Windows 11 as well!
## Many thanks to pafish for some of the ideas - https://github.com/a0rtega/pafish
