Hyper-V Program Manager
A while ago one of the premier screen-saver packages was 'After Dark' - which was renowned for its 'Flying toasters' screen saver. Now - I happen to own After Dark 4.0 - and quite liked all the screensavers it had. Unfortunately it is not compatible with Windows XP - so I cannot run it anymore. However - I have found that it runs under Windows 98 on Virtual PC:
While I will admit that this is exceedingly pointless and foolish - I have now installed 'After Dark' inside a number of my virtual machines that are capable of running it.
BTW - I have found a couple of sites that claim to be able to get After Dark 4.0 working on Windows XP - but none of them have worked for me.
