WSUS settings and Duplicate client ID

Question

I set up WSUS on a Windows Server 2008 R2, a few issues I need help to clarify them:
1) I don't see http://servername:port in  registry under HKLM\software]Microsoft\Windows\Currentversion\WindowsUpdate
I have set up http:server1:8530 in GPO, I am using download from MS directly
2) clients --windows 7 have duplicated client ID from image, the susclientID looks like 3c8405edcet456....somethign like that
I am working on a powershell to remove the duplicated ID for 200 PCs
3) some server client didn't report to WSUS admin console for past 6 months, even I removed susClientID and ClientIDvalidation and rebooted but it didn't work
any suggestions?
Thanks!

Here you find the Key:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
2) clients --windows 7 have duplicated client ID from image, the susclientID looks like 3c8405edcet456....somethign like that

I create a Batch Script for the same issue:
If exist \\Server\Share\%COMPUTERNAME%.TXT goto ENDE
REG DELETE HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate /va /f
WUAUCLT /ResetAuthorization /DETECTNOW
set datum=%date%
echo %datum%
set Zeit=%time%
echo %time%
echo %computername% %datum% %time% > \\Server\Share\%COMPUTERNAME%.TXT
:ENDE
EXIT
You can use it as a Computerstartupscript with Group Policys. After
a couple days many clients will come back to wsus and report.
3) some server client didn't report to WSUS admin console for past 6 months, even I removed susClientID and ClientIDvalidation and rebooted but it didn't work
Look in %windir%\WindowsUpdate.log for Errormessages.
