>Hi Frank,
>
>Works. Can you explain to me what the following means (I don't know what "manifest" means). It may not matter as it seems to work on the PC's I tried it on.
>
>>*!* * For applications that have been manifested for Windows 8.1 or Windows 10.
>>*!* Applications not manifested for Windows 8.1 or Windows 10 will return the Windows 8 OS version value (6.2).
>>*!* To manifest your applications for Windows 8.1 or Windows 10, refer to Targeting your application for Windows.

>>>Hi all,
>>>
>>>Need to detect if user is running on Win 8 vs. Win 10 vs Win 7. It seems that OS(1) returns "Windows 6.01" for Win 7 and for both Win 8 and Win 10 it returns "Windows 6.02" (for Win 8, I had to get someone else to run but they confirmed they were indeed running Win 8).
>>>
>>>Other than the build number returned with OS(5), is there any other function or system var that I can check to tell the difference?
