User-Agent: Get Windows build number from registry

[arthuraraujo-msft]

          as i mention in another comment, while it's undocumented, it's been there as long as I've been at Windows which is a LONG time....for build info it's probably fine for us to use some variant of:

$cv = Get-ItemProperty 'HKLM:\Software\Microsoft\Windows NT\CurrentVersion'
'Version {0} (OS Build {1}.{2})' -f $cv.DisplayVersion, $cv.CurrentBuildNumber,$cv.UBR

which gives the same value as winver.exe, "Version 23H2 (OS Build 22631.3296)" on my dev box.

likely service team just needs a BuildNumber as that's unique across all windows builds ever, e.g.

• The first Windows 10 build number is 10240
• The last Windows 8.1 build number is 9600
• The last Windows XP build number is 3790

so maybe just send up BuildNumber and architecture ID ?

Check with service / telemetry (the latter is now part of Jerry's team) to see if sending up e.g. "Microsoft-SFSClient/1.0 (Windows 22631; amd64)" as an agent string is sufficient for their needs.

Dropping since there is no need for this at the moment. Offline discussion happened.
