The Following few Steps and Tweaks make your Computer fly like a jet….
1. Apply Windows Updates
If you run Windows and you use the Internet, you simply MUST stay up to date with the system patches that come out in response to the privacy and security exploits that are discovered every week. Failure to do so is an open invitation to hackers and crackers to invade your privacy and enslave your computer in a spam spewing network. To get the latest fixes and configure your system for automatic updates, open Internet Explorer, click on Tools, then Windows Update.
2. Remove Unnecessary Software
You may have a bunch of software packages on your hard drive that are no longer needed, or they were gratuitously installed when you downloaded some other package. Toolbars, file-sharing programs, free email enhancers, online shopping "companions" and download managers are notorious for this practice. These uninvited guests can put a big drag on your startup time, cause web pages to load slowly, and generally bog down your computer. Go to Control Panel, then Add/Remove Software to see what packages are installed. Remove the ones you know you don't need, and do a web search to learn about the ones you're not sure about.
3. Scrub The Hard Disk
Both Windows and application programs tend to leave temporary files lying around on your hard drive, taking up space needlessly. A hard drive that is close to being full can cause Windows to act strangely, and will slow down or interfere with efficient disk access and virtual memory operations. And if you surf the web a lot, your temporary internet files folder can become quite large, causing Internet Explorer to slow down or malfunction. Cleaning up unneeded files, scanning for disk errors and defragmenting the hard drive can help to restore some zip to your system. First, open My Computer, right-click on the C: Drive icon, select Properties, then click on Disk Cleanup. (Optional: Select the More Options tab to find and remove even more unwanted files.) To run a defrag, open My Computer, right-click on the C: Drive icon, select Properties, then Tools. Click the Check Now button to scan your disk for errors. When the scan is complete, click the Defragment Now button to run the defrag, which reorganizes your hard disk so Windows can find and access files more efficiently. (It's highly recommended that you close all running programs and disable your screen saver before running a defrag. Otherwise, updates to your files may trigger defrag to restart endlessly.)
4. Shrink Your Startup Selections
There are certain programs that Windows will start every time you boot up your system, and during the startup phase, they're all jockeying for a slice of your CPU. Extra or unwanted items in the startup list will defintely increase your startup time, perhaps by several minutes. To manage the list of startup programs, click on Start / Run, then type MSCONFIG. Press Enter, then select the Startup tab. If you see items in the list you know you don't need to run at startup time, UNcheck the box(es) next to them and press Apply. Some common examples are things related to AOL, RealPlayer, Napster, instant messengers, and video managers. If you're not sure about an item, no big deal. You can turn it off, restart your PC, and see if everything seems to work. If not, you can always go back and re-enable an item in the Startup list. This helpful list or this page may help you decide what to keep or drop.
5. Clean Your Registry
The Windows Registry is a database that enables the operating system to track the relationships between hardware and software. Unfortunately, problems with the registry can make Windows run slower. Sometimes an "orphaned" registry entry can confuse Windows during startup and cause a delay. And in general, slimming down your registry will make Windows run faster. There are several utility programs that will clean your system registry of unnecessary and erroneous entries.

6. RAM and Virtual Memory Settings
When you run out of physical (RAM) memory, Windows will use a check of your hard disk to create virtual memory. This is a nice feature, because it allows application programs to access huge amounts of memory. The only problem with virtual memory is that it's a lot slower than real RAM. So installing extra RAM on the system board is a good idea because it's pretty cheap and easy to pop in. Find out how much your system will accommodate and install the maximum amount. Extra RAM will probably do more to boost your overall system performance than anything else! But getting back to Virtual Memory, it's wise to let Windows manage the amount, unless you are a Wizard, with a capital W. Go to Control Panel / System / Advanced, then press the Settings button under Performance. Click Advanced again, then press the Change button under Virtual Memory. If System managed size is selected, you're all set. If you want to fiddle with the Custom Size options, be my guest!
7. Turn Off Extraneous System Services
We're heading into uber-geek territory here, so be forewarned. Windows doesn't know exactly how you're going to use your computer, so it starts a whole bunch of system services that manage network connections, database access, error reporting, remote access and other nerdy-sounding things. You may not need all these services, and disabling some of them can reduce your startup time and system overhead. But choosing which ones to nuke is a bit daunting, unless you are an expert on Windows operating system internals. Here's my advice... look at these explanations and advice then disable only the ones that you're sure about. If you encounter a problem, you can always go back and turn a service back on.
