what's the time interval of WSUS self refresh

what's the standard of WSUS to differentiate one computer from another, it's
NIC, or OS's GUID, or SN of hardware? how could make WSUS recognize a old
computer as a new one?

if a wuau client doesn't communicate with WSUS, how long time will WSUS
re-recognize the new OS on the old machine?

when is the schedule that WSUS's sql engin do some cleaning job, at midnight?

i need your help, thanks.

Frank

 

PS. how to make WSUS recognize a newly installed OS on a old machine more
quickly?

 

A GUID stored in the registry value "SusClientID" in the registry key
HKLM\Software\Microsoft\Windows\CurrentVersion\WindowsUpdate
which is stored in the WSUS database when the client successfully
'registers' with the WSUS server.

Well... if a WUA client doesn't communicate with WSUS, the answer to any
"how long" question is FOREVER. The clients is responsible for all
communications; if the client cannot communicate, the WSUS server knows
nothing.

There is no application-engineered database maintenance. If you're using SQL
Server, your DBA should set up a standard database maintenance plan.
