The most popular version of Windows is currently Windows 7, though Windows XP has been popular until recent years, when Microsoft officially retired XP and ceased support for the operating system in April 8, 2014. The recently-released Windows 8 has caused much criticism for its new Metro interface, which replaces the traditional Explorer interface, for it's overly-simplistic design, low level of personalization and for being more touch-screen oriented. Similar criticism was made on other products that were given the Metro treatment, like Office 2013.

He then rages at Microsoft and repeated what he said, thus giving him enough rage to leave his room.
- Later on in Episode 2, he has planned to install Windows 7. Like noob Windows users, 30 minutes later he got the "Windows not Genuine" notification from Windows and didn't know how to fix it.
- A bit further in Episode 4, he had planned to install Windows 8 but since 8 is simular to 7, he had the same problem, thus letting anger into himself. He leaves again.
- Possibly coming soon in Episode 23, Leopold may take action against Microsoft or attempt something else. Currently, further information is TBD.
