Windows 7: is there a command line to force to check up for update

Hi



is there a command line to force windows 7 to check for updates?

i know it checks ever day for update while xp at every boot

well is there a command line to run in the start menu or schedule to force windows7 to check?

i know i can click on the update module to perform an immediately check
but i'm looking for a command line , or the name of program (exe) that start to check up

thanks
best regards

To start Windows Update application from command line:
Notice: this only opens the update application and checks available updates. It does not install them.


To install important updates automatically from command line:
Automatic updates must be enabled in order to be able to use this command.

thanks

but this opens the windows update window
it doesn't check for new updates!
i have this settings

Yes it checks if there are any updates available. It does not install them.

You setting should be enough for command line automatic update to work.

May I ask: any particular reason as to why? Is there a difference by checking/installing via the GUI.

I want that all important updates are installed as soon as they are available. That's why I have a batch file in all of my Vista and Seven machines (real and virtual ones) that I can launch when I want to shut down the computer, first checking available important updates and installing them. Doing this I know my systems are always updated.

I've placed a shortcut on desktop, and most often instead of choosing Shutdown from Start Menu, I just double click this shortcut to shut down the machine.

The batchfile:
(this checks if important updates are available, and installs them if answer was yes, shutting then computer down first closing all apps)

^Thanks kindly Kari, very useful info and your script

you can run this
this checks for update at every boot

I understood from your original question you didn't know how to do that. That's why I posted those batch files.

Your attached file modifies registry, and does check the updates when machine is booted.

I do not want to add something to my registry, and I do not want to check updates when booting because installing updates most often requires a shut down or reboot. My method is IMO more practical because you'll run it when shutting down, and there's no registry editing involved.
