Here’s an interesting little morsel from over at Tech-Recipes.com on How to make WindowsUpdate.com allow you to update without verifying your copy of Windows.
Tech-Recipes: Move on over to the updates site Microsoft Updates, now when the page loads it will give you the options for custom or Express, if you were to make a choice now you would be given an error like Invalid CD Key or something to that effect… but if you want your updates any way then put this in the title bar:
javascript:void(window.g_sDisableWGACheck=’all’) and press enter
Then make your selection. The process will continue normally, just leaving out the little part about verifying your Key 🙂
