WSUS Options
- Gerald Novak
/bypass_wsus !!!DEPRECATED!!!
This option is deprecated, use /UseUpdateService instead.
The bypass_wsus option bypasses any configured WSUS and forces WuInstall to access the Windows Update site.
If a WSUS is configured, WuInstall changes the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU, Value UseWuServer from 1 to 0, which means that no WSUS should be used.
If you type
WUInstall.exe /search /bypass_wsus
and a WSUS is configured, the output is:
You are using WSUS Server http://mywsus.local:8530 bypass_wsus specified, bypassing WSUS ... successful!
After the execution of WuInstall, resetting the UseWuServer value to 1 restores the initial state.
bypass_wsus specified, reactivating WSUS ... successful!
When the execution of WuInstall is aborted for some reason before WuInstall can reset the registry value, it has to be reset manually!
/use_wsus wsus_address
The /use_wsus option works similar to the /bypass_wsus option, but you can specify another WSUS, which is valid during the execution of WuInstall (or it allows you to switch from no WSUS at all to a certain WSUS).
WuInstall manipulates the following registry keys:
- HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU\UseWuServer: is set to 1
- HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\WUServer: is set to the specified wsus_address
- HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\WUStatusServer: is set to the specified wsus_address
and stores the initial values for resetting them after WuInstall has finished.
For example, if you have WSUS http://mywsus.local:8530 configured, and want to go to the WSUS http://mywsus2.local:8530, you type:
WUInstall.exe /search /use_wsus http://mywsus2.local:8530
and WuInstall puts out:
You are using WSUS Server http://mywsus.local:8530 use_wsus specified .... WUServer and WUStatusServer successfully set to http://mywsus2.local:8530
After the execution of WuInstall, the initial state is restored (in this example, the WSUS is reset to http://mywsus.local:8530)
use_wsus specified, deactivating WSUS again resetting WUServer to http://mywsus.local:8530, WUStatusServer to http://mywsus.local:8530 ... successful!
When the execution of WuInstall is aborted for some reason before WuInstall can reset the registry values, they have to be reset manually!
/use_mu_on_error
When an error occurs while trying to install an update using WSUS, WuInstall automatically tries again to install the updates bypassing the WSUS using Microsoft Update.
/use_wu_on_eror
When an error occurs while trying to install an update using WSUS, WuInstall automatically tries again to install the updates bypassing the WSUS using Windows Update.
