I got bored so I decided to see how many different OSes I could get running at once.

From left to right mostly:

• MS DOS 6.22
• Windows 1.01
• Windows 2.03
• Windows 3.1
• Windows for Workgroups 3.11
• Windows NT 3.51
• Commodore 64
• Windows 95
• Windows NT 4
• Android
• Microsoft Bob
• Windows 2000
• Windows XP
• Windows Vista
• ChromeOS
• OS/2 Warp 4
• BeOS R5
• Windows 8
• QNX
• Haiku
• Ubuntu
• Windows 98
• Windows ME
• MacOS 9.0.4
• MacOS X 10.2 Jaguar
• MacOS X 10.8 Mountain Lion
• Blackberry 10

And of course a Windows 7 host.

I had to run Windows 98 and Windows ME in Virtual PC since they were really difficult (I gave up) to get going in VirtualBox. I also had to disable Aero and turn almost everything off, borrow RAM from my girlfriend’s computer, as well as her monitor.. And tweak some services in Vista and Windows 8 to slim them down enough to run all of these at once.. I should probably get more than 4GB of RAM and a Core 2 Duo if I want to add any more..

Once I heard a saying “the simple minded are easily amused”. But I’d hardly call this guy, a person that is able to run 28 operating systems simultaneously on a computer with just 4GB of RAM, simple minded.
