Go to control panel, then find the windows update tab, click view update history, underneath where it says "review your update history" you will get a link to remove an update, just click on the blue wording that says "installed updates,troubleshoot problems with installed updates" then right click on any update to uninstall it, hope this helps....Aah soz m8 just realised you asked if you can install all at once, i don't actually think you can do that, if your blue screen just started just remove the last updates, or if you have installed a new program or new hardware try uninstalling and see if you still get the problem, Dean is correct also, it should give you a message when it crashes, it will be a clue to what the problem is, but you gotta be quick.
