Poll: Why are you still using Windows 7?

Because windows 7 is the last "good" version.

Microsoft has produced lots of versions of MSDOS and Windows. A surprisingly small number of versions can be considered "good" (and that "good" is relative to the era, not absolute):

MSDOS: 2.1, 3.3, 6.22

Windows: 3.1, Windows 98, Windows XP, Windows 7

The other versions were mainly mediocre with several being outright bad:

MSDOS 4, Windows ME, Windows Vista, Windows 8.x

Because Windows 10 sucks and is a spy machine and sometimes we need an installation for testing apps on this OS before release

Because despite their support saying the software works on Windows 10 -- and having half a dozen calls with their techs and doing everything they tell me to -- I cannot get my Primera 4102 disc duplicator running on Windows 10.

Because Windows 10 is an endless beta with forced updates/reboots.
