Since the dawn of Windows, power-user tipsters (us included) have proffered hundreds of suggestions with the promise of improving your PC’s performance or streamlining its operation. The tip-givers have the best of intentions, but do all of those tweaks, registry hacks, utilities, and “undocumented secrets” really make any difference? To our surprise, in a number of cases, it turns out that tips that sound great on the surface don’t actually do anything when you put the screws to them. And some of those complicated registry hacks are more easily done with tools like TweakUI, saving you a lot of hassle.
We put 25 of the most commonly published XP and Vista performance tips and registry hacks to the test. Do the speed tweaks yield dividends? We clocked performance with PCMark and timed boots and shutdowns repeatedly after making the changes suggested in the tips. In the end, we found that many tips were right on the money, but some were outright wrong or just a waste of time. Some tips fell into the gray area in between, offering some improvement but perhaps not enough to merit the trouble of the hack to begin with.
