Windows 7 Successfully Installed on a Pentium II

When Microsoft made the Windows 7 RC available, it also issued an official list of system requirements for anyone hoping to install the OS:

  • 1GHz processor (32- or 64-bit)
  • 1GB of main memory
  • 16GB of available disk space
  • Support for DX9 graphics with 128MB of memory (for the Aero interface)

Not exactly monstrous and the same as what you needed to run Vista years ago. That said, one Windows enthusiast decided to push the limits and in a kind of “how low can you go” scenario, managed to get Microsoft’s latest OS running on a Pentium II at 266 MHz CPU, 96 MB of RAM and a 4 MB graphics card.

The user hackerman1 posted about his efforts on the Windows Club Forums for the world to see and his fellow posters we, like the other users on the forum, were suitably impressed. Hackerman1 said he did three different tests (128 MB, 96 MB and 64 MB of RAM). Of these, he had success with both 128 MB and 96 MB, while his 64 MB attempt returned error messages reading “insufficient memory.”

Hackerman1 went on to say that he also has a Pentium I with a 166 MHz CPU and a 1 MB graphics card and says if he can dig up the PSU, he’s going to test that next. Check out the screenshots below.

    But how well does it run crysis.....

    Seriously - kudos on getting it to work, you've got to wonder whether its any use for anything though - I bet even wordpad or calculator take an age to load ... i'd like to see some startup / app benchmarks :)
