I did answer yes as I did install WinXP and MS Office with illegal keys in VirtualBox. I bought this computer with Windows and MS Office installed from my employer and I should have a license via my employer. Don't know if it is allowed to run in virtualisation though.
Have lot's of cracked and copied 880K amiga disks, don't use it anymore though, My amiga OSes (3.0, 3.1, 3.5, 3.9, Intent based AmigaOS SDK and 4.0) and software I use is fully licensed.
