Short answer -- sure, anything can happen.
More comprehensive assistance will depend upon more information about your machine resources, previous configuration of operating system, other installed software, and specific items included in the "huge" update.
To keep track of, and understanding the actual items (by date of install) included in any one update, click on the Windows Update applet in your Start - All Programs... then Select the "Review Your Update History" in the left-hand menu.
You can even copy/paste from that list, if there are specific updates that you wish to investigate in specific.
The help you receive here is free.
