What version of Windows are you using?
Remember, we’re talking about which version of Windows, not
which version of Word!
For all versions of Windows, just look for the "Start" button which is generally
found on the left, bottom corner of your screen, depress "Start" and go
Start > Settings > Control Panel, then look on the gray bar along the top of the
Control Panel folder and find "Help" which you should depress and see "About
[your version]" as in this picture of a Windows NT:
Here are some other ways to figure out which version of Windows
If you’re using Windows2000, you’ll see that written in the
box that you type your logon name and password in every time
you restart your computer.
For WindowsXP, WindowsNT and Windows98, just depress the Start button and tilt your head to
the left. You’ll see this info written sideways!
Another method is to find the “My Computer” icon on your desktop.
Right click the mouse on it and then click on “properties”. The information
will be given there.
I’m sorry I don’t have any information on typing Persian on other
versions of Windows which I don’t have access to. I know the
FarsiLang patch works on WindowsME and Windows95,however I’ve not
had the chance to try out either.
