I'm trying to understand why Powershell would get back a different version number for a DLL file than what both the file properties page from Windows Explorer, and a WMI query shows. (I apologize in advance if this doesn't correctly qualify as a coding question.)
The scenario:
Running the following powershell command:
(get-item C:\windows\system32\rdpcorekmts.dll).VersionInfo.ProductVersion
This returns the following:
6.1.7600.16385
However, this version number is incorrect. When examining the version information from Windows Explorer, you see the following version (sorry, I tried posting a small screenshot of it, but I don't have enough rep; I'm new here):
6.1.7601.17767
In addition, a WMIC query shows the same results as Windows Explorer:
WMIC path CIM_DataFile WHERE (name="c:\\windows\\system32\\rdpcorekmts.dll") get Version
WMIC result:
Version
6.1.7601.17767
I really don't understand why they would be different. I would really like to return this value using Powershell, but now I'm not sure if I'm just overlooking something, or if I ran across some kind of odd bug, but the version mismatch between the two methods is confusing. As a note, I've run variations on the method to get this back in Powershell (e.g. Get-ItemChild and Get-ItemProperty), and I get the same incorrect version result.
Any ideas on why?
