Don't believe everything you read online. Spend a few minutes searching online and you'll find hundreds of PC speed-ups guides and tweking tools, each promising they have the magic ingredients to bring new life to your system. But can you really trust them? Not neccessarily - many of their tweaks are entirely useless. One common tip claims it forces Windows to automatically unload DLLs used by an application just as soon as it closes, for instance, freeing up RAM. This option appears in many tweking tools, and yet it's not worked since Windows 98. Another tip says you can improve network and internet speeds by allowing your network cards CPU to take over some of the data transfer work. Exellent! Except, well, Windows does this anyway, when appropriate. There's no need for this tweak at all. And a particularly dubious claim says it's good idea to clear out the contents of your Windwos\Prefetch folder occasionally. But this is where Windows stores the data it needs to improve boot times, and deleteing these files only slows you down. Be wary, then, Don't assume that just because a tip is online, or in a tweaking program, that it actually works. By all means try tweaks out, but test the results to make sure they deliver. And if you're changing a registry value, make a note ot its original value, so it's easy to restore later. Say all this, don't believe everything you see on the internet... there are so many "speed-up" tips that actually will harm your system and slow you down.
