Display Hidden Devices in Windows

We know that when you install a driver in Windows it remains there until you uninstall it. You can follow this procedure in order to uninstall drivers for hardware that no longer exists on the machine:

  • open cmd
  • run “set devmgr_show_nonpresent_devices=1”
  • run “start devmgmt.msc”
  • Click Show Hidden devices from the View menu
  • You will now see all the installed drivers on your machine, even those that your system no longer uses them.
  • You can now uninstall them.

Microsoft Update Services SUS

By default when a pc / server connects to an SUS server, an susclientid is created on the pc / server. In case that you clone that pc / server, the same susclientid will exist on the cloned pc / server and the SUS server will only have one entry of this pc / server. In order to change it on the new pc / server you have to follow the following procedure:

1. Stop Automatic Updates service
2. run regedit and go to HLM/Software/Microsoft/Windows/CurrentVersion/WindowsUpdate
3. on the right site of Registry Editor delete SusClientId and SusclientidValidation
4. Start Automatic Updates service
5. open cmd and run: wuauclt /detectnow

Now a new susclientid will be created on the machine and in a few seconds it will be created on the SUS machine.
Tested on Windows XP SP3 for the moment.
