How do I tell if Im on Server 2003 R2?

Question

Just wondering how I tell I was sure I installed a VM with R2 but it doesnt say.

Answer 1

If you're looking for a programmatic way to do it, you can use PowerShell and WMI to get the same string as in My Computer -> Properties...

powershell -command "$str = (gwmi win32_operatingsystem).name; $str -like '*R2*'"

(True if R2, false if not R2)

Answer 2

Click start then run and type WINVER and hit enter. It will tell you if it is R2.

Answer 3

Where did you look? Right-click My Computer and get Properties. It should give you the precise edition.

Answer 4

Start -> Run -> winver.exe from within Windows or click on the Summary tab in the vSphere client to see what you selected (but not necessarily what is installed)
