wuauclt.exe command line switches

[Pierrot Robert]

Hi,

Does anyone have a list of all wuauclt.exe command line switches (e.g.
/detectnow) ?

Thank you.

Hi,

wuauclt.exe /detectnow is the one documented.

Happy Patching,

Actually, there are /two/ documented switches.

/detectnow to execute an immediate detection from the client.

/resetauthorization to purge (timeout) the WUA targeting information cookie.

The second switch must be used with the first, and must be executed exactly
in this fashion:
wuauclt /resetauthorization /detectnow

The /resetauthorization switch is only useful if the client has been
reassigned to a new target group and is not properly picking up that target
group assignment (most likely because it's using a cached targeting cookie).
The switch will force the deletion of the cookie.

Oops I missed the second one (/resetauthorization).

Any idea of the undocumented ones? I googled and found some that did not
work; they may have been just a wishlist.

I'm looking for one that can start the (already downloaded) installation
process from a command line, the equivalent of having the user click the
yellow shield icon -> "Express Install".

There are no undocumented switches.

The ones you found existed in a prior 'beta' version of the WUA and were
there strictly for internal development testing purposes.

I learned of them sometime last year. Did a bit of testing and found their
function extremely limited. At best, the only one that actually did anything
merely launched the UI of the WUA, but nothing more.

I'm not aware of any way to do that from the wuauclt.exe executable, Dave.
Your best bet is VBScripting.

I believe Rob or Torgeir have links to scripts that will do this.

Found it, eventually. Works a treat. Thanks much.

wuauclt /r /reportnow

This is very useful command which sends all queued reporting events to
the server immediately

I found this on another site:

Reposting for you guys.
***
From a dump of the .exe (W2k3 R2 version ) we can extract the followin
options:
/DetectNow
/ReportNow
/RunHandlerComServer
/RunStoreAsComServer
/ShowSettingsDialog
/ResetAuthorization
/ResetEulas
/ShowWU
/ShowWindowsUpdate
/SelfUpdateManaged
/SelfUpdateUnmanaged
/UpdateNow
/ShowWUAutoScan
/ShowFeaturedUpdates
/ShowOptions
/ShowFeaturedOptInDialog
/DemoUI

Most of these options don't give any noticable response, but that may b
because of the state of the service.
The command 'wuauclt /ResetAuthorization /DetectNow' worked for me righ
away.
***
Hope this help

Or because there's no code behind the switches.

There *is* a reason the options are not documented!

Yes, this is one of only *three* functional command options.

The other two are:

wuauclt /detectnow

and

wuauclt /reportnow

Hope this helps

Not really. It's ancient information and you're replying to an ancient
thread.

No need to need to be a troll. A simple explanation would have sufficed
without being a jerk. I simply reposted some info I found on another
site while researching the same topic as I just learned about the
command the other day. If you make yourself feel better by making
others feel inferior to you, then I hope you find something better to do
with your life.

Trust me.. I'm not the troll. But the *information* is five years old and
it's every bit as invalid today as it was when it was first posted by the
person who thought something useful was being posted the first time. If
somebody had pointed out in the source where you got this bad information
that it was bad information, perhaps you would not have been so excited to
post whereever else you might have posted it. Now, in this thread, that's
been done, and hopefully another novice WSUS admin won't use this thread to
proliferate this bad information other places.

If you make yourself feel better by making
others feel inferior to you, then I hope you find something better to do
with your life.

I'm not trying to make anybody feel inferior.. I'm merely suggesting (and
perhaps in a poor manner) that you ought to read the thread, notice the
datestamps, and *research* the situation before you offer up the dozenth
repost of the same useless information. The lesson to be learned is to not
blindly repost information you "find on the net", until you've verified it's
accuracy and value.

Perhaps, even, if you had *asked* if it was valid information, rather than
posting as if it were . . . ???
