Customise System Restore

There was very little you could do to configure System Restore in Vista, but Windows 7 improves the situation with a couple of useful setup options.

Click the Start orb, right-click Computer and select Properties > System Protection > Configure, and set the Max Usage value to a size that suits your needs (larger to hold more restore points, smaller to save disk space).

And if you don't need System Restore to save Windows settings then choose the "Only restore previous versions of files" option. Windows 7 won't back up your Registry, which means you'll squeeze more restore points and file backups into the available disk space. System Restore is much less likely to get an unbootable PC working again, though, so use this trick at your own risk.
