Vista not updating in Windows Update? Check the version of IE.

Here’s a tip in case you ever run across a old PC with Vista that isn’t installing windows updates: check the version of internet explorer.

If version 7 is still installed (which you can see under HELP – ABOUT), that’s the main problem.

Update IE to version 8 for Vista first, then reboot and try running windows update again.

From there, you should be able to get the service packs and IE 9.
