[wpkg-users] Distinguishing OS version

[Mikhail Joseph Salviejo]

Good day to all,

Does anyone knows how am I going to test whether the OS is Windows
2000, XP or 7?

The scenario is like this.

I am going  to install Firefox yet some features of the package must
be not be read
if its on 2000 system (like for example 2000 does not accept taskkill)
, yet it must be read by XP & 7.

Computers here are mixed OS some still on 2000, some on 7, and many on XP.

Can anyone help me.

Thank you in advance.

Your Truly
