Windows 7: the complete guide

Troubleshoot problems and maintain your PC

Discover how to use Windows 7's tools to find and fix glitches and keep your computer running smoothly


Windows is packed with tools to help you maintain your PC and quickly resolve any issues you come across.

These can all be accessed from the Action Center, visible as a white flag in the Taskbar's Notification area. Click this once and a small pop-up window will reveal any urgent messages about errors or tasks you need to perform, like backing up files.

Click 'Open Action Center' to open it fully. Anything that needs urgent attention is flagged, but it's also worth exploring the rest of the section to see what parts of your system are monitored by the Action Center.

Fix problems

If you're having problems with your PC, click the 'Troubleshooting' link, which enables you to browse through a large number of troubleshooting tools divided into categories like Programs, Network and Internet.

If you can't find the troubleshooter you're looking for, use the Search Troubleshooting box, which will also search online.

It's important to keep your PC's software up to date. Windows Update should be configured automatically, but check it occasionally for optional updates, which may include some hardware driver updates too.

If your computer suddenly stops working properly, it may be linked to a recent system change, like a corrupt update or new program installation.

Click 'Start', type System Restore into the Search box and launch System Restore to revert your computer to a time when it worked properly. Start with the recommended Restore Point and only choose an older backup if this fails to resolve your problem.
