There are a number of ways you could get relevant information. Parsing the
product id sounds a bit of an extreme approach imho ;-) [although possible
and worth a thread in itself]
From the registry as you mentioned under
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
(Get-Item "HKLM:SOFTWARE\Microsoft\Windows
NT\CurrentVersion").GetValue("ProductName")
(Get-Item "HKLM:SOFTWARE\Microsoft\Windows
NT\CurrentVersion").GetValue("EditionID")
would distinguish between Windows Server 2008 and Vista
Other options ..
(Get-Item "HKLM:SOFTWARE\Microsoft\Windows
NT\CurrentVersion").GetValueNames()
or you could use Win32_OperatingSystem
Get-WmiObject Win32_OperatingSystem | fl -property *
eg
(Get-WmiObject Win32_OperatingSystem).Caption
(Get-WmiObject Win32_OperatingSystem).BuildNumber
OR
[environment]:
sversion
eg
[environment]:
sversion.Version.ToString()
and split further....
[environment]:
sversion.Version.Major
[environment]:
sversion.Version.Minor
[environment]:
sversion.Version.Build
[environment]:
sversion.Version.Revision
A combination of the above should provide you with sufficient information.
