The advice regarding prefetch is good. The prefetch system is completely system managed and there is no need for manual intervention. But the description of prefetch is incorrect, or at least misleading.

Most modern operating systems use the demand load principle. When an application is started the system does not load all of the program code and data at once. Program segments are loaded only as needed and in the order they are needed. The problem with is that the order of access is not very efficient. Prefetch files are are a list of indexes to program segments, not the data itself. With this list Windows is able to sort the load order into something that is more efficient and thus reduce load time.

But none of this really matters. The best you can do with the prefetch folder is just leave it alone.

This is somewhat confusing. In the article – 10 tips to improve Windows XP performance- on this site, tip no. 8 states as,
{Tip 8:
Go to Run. Type prefetch, a window would open. Select everything in the window and delete it. Windows has this nasty habit of saving all the programs opened and it uses the prefetch option to load it again faster. But it slows down the system. Use it frequently to improve your system performance.}
