Make Your Windows Fast As Never Before

Indexing Services is a small little program that uses large amounts of RAM and can often make a computer endlessly loud and noisy. This system process indexes and updates lists of all the files that are on your computer. It does this so that when you do a search for something on your computer, it will search faster by scanning the index lists. If you don't search your computer often, or even if you do search often, this system service is completely unnecessary. To disable do the following:
1. Go to Start
2. Click Settings
3. Click Control Panel
4. Double-click Add/Remove Programs
5. Click the Add/Remove Window Components
6. Uncheck the Indexing services
7. Click Next

OPTIMISE YOUR PAGEFILE

If you give your pagefile a fixed size it saves the operating system from needing to resize the page file.
1. Right click on My Computer and select Properties
2. Select the Advanced tab
3. Under Performance choose the Settings button
4. Select the Advanced tab again and under Virtual Memory select Change
5. Highlight the drive containing your page file and make the initial Size of the file the same as the Maximum Size of the file.

Windows XP sizes the page file to about 1.5X the amount of actual physical memory by default. While this is good for systems with smaller amounts of memory (under 512MB) it is unlikely that a typical XP desktop system will ever need 1.5 X 512MB or more of virtual memory. If you have less than 512MB of memory, leave the page file at its default size. If you have 512MB or more, change the ratio to 1:1 page file size to physical memory size.
