Tips for home use |
Service packs for Windows XP, Windows Vista, and Windows 7 can be downloaded using Windows Update, an easy and free way to help keep your PC safer and running smoothly.
If you’re using Windows Update, service packs are downloaded, but aren’t installed automatically. You’ll need to install service packs manually. If you’re not using Windows Update, go to the Microsoft Update website to download service packs and then install them.
