1. Reduce Your Recycle Bin Size.
Data capacity of a hard drive is now available in large quantity now days like you can easily purchase a terabyte hard drive from market easily. By default the recycle bin size for the hard drives is 10 % if the hard drive's data capacity is 500 Gb it would be useless to define a 10 % default recycle bin settings. Change it to 2 to 5 % or it can be 5 Gb to 10 Gb.
2. Turn off Remote Desktop Management
Remote desktop management is a windows utility that allows other to access your PC remotely. Its very useful if your computer is a part of network but its always a danger as hackers can easily penetrate into your computer. So my recommendation is to turn it off, use Team viewer instead.
CHKDSK is essential tool for windows xp maintenance, it should run from time to time. It will scan the disk for errors, fix logical errors, detect and mark bad sectors, so that Windows will no longer try to use them. This way it can prevent your computer from becoming unstable.
4. Defrag Regularly
Defrag is another essential tool for windows xp maintenance. Badly fragmented disks can cause a lot of problems, like general system slowdowns, slower start-up and shutdowns, and even computer crashes. Basically, your hard drive is the slowest part of your computer and file fragmentation makes it even slower.Like any other defrag utility it gathers file fragments that are scattered all over your disk and writes them into adjacent clusters.
