Disable Automatic Windows Update in Vista
Windows updates are important, but quite frustrating when it happens at the wrong time. Here's my problem with it - My internet plan has a bandwidth cap of 1 GB per month, but no caps are applicable during the night; its unlimited at night. So I would prefer that Windows updates are downloaded and installed when my internet connection is free of bandwidth caps. Similarly, you may also not want those updates to be installed just before your all important presentation. A manual update of Windows give you more control of when to download and apply it. So, here's how to do it.
Steps to Disable Automatic Updates in Vista
1. Open Windows Update by clicking the Windows Start button and type Windows Update. The Windows Update program is listed. Click it. Alternatively, you can open the tool from Control Panel.
2. On the left pane, click Change Settings.
3. Select the 'Never check for updates' option and click Ok.
That should do it. Remember to manually update Windows from now on. To enable automatic updates again, just follow the same steps and select 'Install updates automatically' option.
