Windows 7: How To Improve Computer Performance

You can clean reinstall which is actually better than a new computer since most are larded with sponsors' bloatware: http://www.sevenforums.com/installation-setup/125874-re-install-windows-7-a.html#post1086729

Until then you can clean up a factory bloatware install using these tips:

Uncheck everything in msconfig>Startup except AV and gadgets/sticky notes if you use them. Google the other listings to find out what they are. The factory utilities have better versions built into Windows 7 so they can all go except for notebook battery and hard drive monitors which can be helpful. The rest are freeloaders on CPU/RAM and Startup that can wait to start until you run them. http://www.sevenforums.com/tutorials/1401-startup-programs-change.html

Decide which programs you can do without over time, then use Revo Uninstaller in Advanced mode to uninstall them. Revo will first run the Windows uninstaller but when prompted to restart instead click "Next" to delete the bolded hidden Registry Keys and files which Revo cues up. Revo sets a System Restore point in case you delete something which needs to be restored.

Use a lightweight free AV like MS Security Essentials or Avast 5 with the Windows Firewall to gain back performance from more bloated AV's.

Check optional Windows Updates regularly for driver updates. You can trust Updates given by Windows 7 as they rarely malfunction and keep your Firewall fortified.

Enable automatic hardware driver updating: http://windows.microsoft.com/en-US/windows7/Automatically-get-recommended-drivers-and-updates-for-your-hardware

Monitor Event Viewer>Admin View to google repeat errors to find how others have resolved them. Check also the Performance log on Advanced Tools page accessed by clicking WEI score link at Computer>Properties. Look for cued issues at top of Tools page, Generate a System Health Report.

Type "Solutions" in Start Search box to see solutions to problems sent and not. Windows 7 is interactive so always send Problem Reports.
