Pc PitStop will give you a wealth of information about whether you have enough disk space, how fragmented your drives, whether you have enough memory and many other things discussed below.

2. Make sure you have enough memory.

You can find out how much you have by clicking on the System Icon in the Control Panel. The amount is on the first tab that comes up, the General Tab.

With Windows 2000 or XP, you really should have at least 256 MB of memory and 512 MB is a more comfortable amount.

3. Make sure you have a fast enough processor.

Only Windows XP will show you how fast your processor is, again see the image on the right. For other versions of Windows, try the free MyCPU from: http://www.seelhofer.ch/mad/. It will give the CPU speed.

500 MHz Processor is really the minimum these days. If you have less than this, spare yourself some frustration and buy a cheap new computer for $350-$400 from Dell, HP, Compaq, E-machines, or Gateway.

4. In the BIOS (or "Setup") stop floppy seek, stop memory check (Fast Boot), and put the disk on best performance setting instead of silent if you have it.

For a faster boot up enter your Bios, by clicking the Delete, F2, or F12 key or whatever flashes on the screen when you turn on the computer. Next choose boot order, and remove all entries except the first one which you should set to your hard drive. This will stop the most of the time useless seeking of a floppy disk at boot time.

If you need to reinstall Windows or some other operation, you can always go back and change this entry to floppy or CD. Also there should be a setting in your BIOS to make the boot, quick. All this means is that your PC will not do the most of the time useless checking of your memory at boot time.

5. Patch your computer!

That is go to Windows update and download all the patches for your operating system.

Better yet, go into the Control Panel, choose Automatic Updates, Choose Automatic (your screen might look different with a different version of Windows). Make it Every Day at a time when you are not using your computer (say 2 AM).

Generally if you have cable or DSL, despite the risk of infection, computers should be kept on and attached to the Internet. This is to allow antivirus and security patches downloading at off-peak hours.

6. Bring your antivirus program up to date and do a full virus scan of your computer.

Bring your antivirus program up to date and regularly do a full virus scan of your computer.

Check your antivirus program as it will tell you when the last full scan was done. You may be surprised to see it is not what you thought, but was last done months ago.

Also try WinHki Anti-Virus, which acts as a supplement to normal Anti-virus program like above. WinHki calculates the checksums ( a mathematical calculation extremely difficult to fool) of your files on initialization. After that, whenever a virus changes a file it will be flagged by WinHki because the checksum will change.

7. Make sure you have no spyware.

Make sure you have no spyware, by running at least a couple different spyware programs.

The last program tests for trojan horses and key loggers that the others don't, but is weak in terms of the number of spywares detected.

The commercial programs SpySweeper and especially PestPatrol are good too, the latter testing for key loggers, in memory spyware etc. and may be the most comprehensive spyware checker of all and only $39.95.

8. Stop unneeded startup programs.

Stop unneeded startup programs. New installation of software often adds unneeded startup entries in any of several different hidden locations. These programs will start when Windows starts and take up resources.

The best free program to deal with this problem, is in my opinion, Startup Inspector for Windows. If you use this program, be sure to select the "Consult" Button in the upper left of GUI. This will make the program search through its database of startup programs and tell you whether the software is necessary or can be safely removed from the bootup sequence.

Another good choice is Codestuff Starter. This free program has the additional advantage of having a sort of Power Task Manager which will tell you all the programs that are currently running and all their dll dependencies. You can also sometimes get info about the manufacturer of the running program.

Unfortunately you will manually have to look up your entries in other resources to see whether the software is necessary for normal functioning. The best databases for checking whether programs are necessary at start up are here (one page), here (searchable), and here (Info used by Startup Inspector).

For real expert list of Start- Up programs including browser helper objects try Hijack this. "This is an experts’ tool! — an awesome weapon in the fight against adware, spyware, and other parasites, Like other powerful weapons, wield it carefully! HJT displays legitimate and illegitimate programs without judgment, so don’t just remove everything it finds; but the comprehensive list it generates finds things no other detection tool will catch. (HJT is also useful in seeing what else your computer is running without your knowledge.) Save the log and post it to a new thread here. To learn more about what HJT shows you, read this excellent tutorial. By Merijn Bellekom"

9. Defragment your hard drive regularly.

Defragment your hard drive by choosing Start -> Programs -> Accessories -> System Tools -> Disk Defragmenter. This should be done every week if possible and can take several hour, so again do it at night or while your at work. There are some free disk defragmenter scheduler solutions, so you can "set it and forget it." They are startdefrag (excellent little program), autodefrag (you need to use Windows Scheduler to start), Lexun Freeware Drivecare (Windows Scheduler needed again). There is a Microsoft article that tells you how to use Scheduler (Start -> Programs -> Accessories -> System Tools -> Scheduled Tasks) to schedule defragmentation.

Also defragment your page file. This step is not done by the native Windows defragmenter nor any commercial defragmenter (I think -probably wrong though). the SysInternals one does it for free.

10. Clean your registry with a free registry cleaner (and optimize it with NTREGOPT).

Clean your registry with a free registry cleaner. Over time the registry gets filled with unneeded entries which slow the computer. Run the programs to find the entries, select them all and hit the delete key. These programs are in wide us and are safe. Good free ones are: TweakNow's RegCleaner, HoverDesk's RegSeeker (it has other functions too), and ToniArt's EasyCleaner.

Here are the notes on NTREOPT: "Similar to Windows 9x/Me, the registry files in an NT-based system can become fragmented over time, occupying more space on your hard disk than necessary and decreasing overall performance. You should use the NTREGOPT utility regularly, but especially after installing or uninstalling a program, to minimize the size of the registry files and optimize registry access.
The program works by recreating each registry hive "from scratch", thus removing any slack space that may be left from previously
modified or deleted keys.
Note that the program does NOT change the contents of the registry in any way, nor does it physically defrag the registry files on the drive
(as the PageDefrag program from SysInternals does). The optimization done by NTREGOPT is simply compacting the registry hives to the
minimum size possible."

11. Stop unneeded Windows services.

Stop unneeded Windows services. Services are again programs that Windows starts up automatically at startup. Many of these are not needed and stopping them can help speed up you considerably. To get to services, in Windows 2000 and XP, right click on My Computer and choose Manage. Then choose services down at the bottom. Now, consult any one of these lists to see which services are needed: here, here (reference by many) or here (detailed explanations with references to Microsoft articles. Tweakhound (first link) also has a batch file which is posted on PC Worlds Site, which will stop a lot of unneeded services. It is here. Beware though it will turn off all fancy display elements of Windows XP and make it look like Windows 98.

12. Turn off fancy desktop backgrounds, screensavers, and the Hibernation Feature.

Turn off fancy desktop backgrounds, and screensavers. Elaborate background pictures and fancy screensavers can take up an enormous amount memory. These operations can be done by right clicking on a blank part of your Desktop and choosing "Properties." Go to the Desktop Tab and set the Background to "None." On the screensaver Tab, set the Screensaver to "None."

13. Turn off Windows animations.

14. Use the Disk Cleanup Utility.

Pick a time just before you will not be needing your computer for a long stretch, and run the Disk Cleanup Utility. The process can go very fast or it can hang your computer for hours.

You can be aggressive about what to delete, although if Disk Cleanup finds Office Setup Files, its generally better to keep them. This is because if you ever update MS Office via the Microsoft Office Website (http://office.microsoft.com/en-us/officeupdate/default.aspx) its generally handier to use the files on your computer, rather than find and load the Office disks (although finding the setup files is difficult too).

Also keep setup logs as they are sometimes necessary for software uninstallation.

There are many freeware tools out there that can help you do the same thing as Disk Cleanup and more, but be careful not to delete uninstall launching executables themselves (as some programs do) as these are obviously necessary for software uninstallation, if you decide to do so later on down the line.

15. Delete unneeded programs.

Delete unneeded programs. These clog up your disk, registry and slow the display of your Start Menu. You can do this by clicking on:

16. Delete unneeded files.

Delete unneeded files. Apparently once your disk gets past the 50% full its performance degrades and as it gets near the full mark, it seriously degrades.

17. Disconnect unneeded or little used Network Drives.

If you have a network or home network and you have used the My Computer or Explorer option "Map Network Drive," you may have network mappings where the drive or folder no longer exists or is accessible from your PC.

Unfortunately, this greatly increases time before your Desktop appears after you log on (or a plain start your computer if you do this automatically and by pass the login screen). What happens is the PC will try a set number of times to contact this drive or folder before giving up, but this can be a minute or two. In fact according to one technician I know he has seen it delay boot up 30 minutes!

18. Use the Quick Launch Toolbar.

This is not displayed by default, so right click on a blank part of the toolbar and choose toolbars and then check Quick Launch, see below:

The Quick Launch Toolbar allows you to start frequently used programs without opening the Start Menu or going to the Desktop. You can drag shortcuts onto toolbar from the Start Menu (which will cause them to move off the Start Menu) or your Desktop (which causes them to be copied).

19. Use keyboard shortcuts.

Use keyboard shortcuts. Once you get in the habit of using these, they are such a boost to efficiency.

Ctrl - a - Selects all items on a page including	Ctrl - x - Cuts selected items	Ctrl - c - Copies selected items
Ctrl - v - paste the current item on the clipboard	Ctrl - p - prints your current document or Webpage	Ctrl - n - opens a new IE Window
Print Screen - places an image of your screen on the clipboard for pasting into Word or Paint or another image program	Alt-Print Screen - places an image of the current active window on your clipboard	Tab - moves from one blank (field) to the next in a form
Shift - Tab - moves to the previous blank (field) in a form	F1 - Opens the Help Menu for the active program	F2 - Allows renaming of a file
F5 - refreshes the display of your current Window	F11 - makes IE go to full screen	Home - brings cursor to beginning of a line
Ctrl- Home - brings cursor to beginning of document	End - brings cursor to the end of a line.	Ctrl - End - brings cursor to the end of a document.
Shift - [Left or Right] Arrow Key - highlights one character	Ctrl - Shift - [Left or Right] Arrow Key - highlights a whole word.	Ctrl - {Right or Left] Arrow Key - moves the cursor through the document one word at a time.
Ctrl - [Up or Down] Arrow Key - moves the cursor through the document one paragraph at a time.	Double Click on a Word - Highlights the word.	Triple Click on a Word - Highlights the whole paragraph.

20. Don't wait for Internet Downloads, start them and move onto something else.

Don't wait. You've visited a search engine and got a list of sites to check out. You click on the first link, and it's taking ages to load. Don't hang around waiting, just click on the Stop button.

Often the bulk of the page will appear immediately. If it doesn't, hit Reload to fetch the rest. An alternative approach is to work your way down the list of sites, right-clicking on the best links and choosing Open in New Window.

Once you have three or four windows open, switch between them, viewing whichever page is displayed first.

21. Break folders up with large amounts files and few folders, to many folders containing manageable amount of files.

The effect of this is to cut down the amount of time Windows takes to build views when traversing folders.

Windows may stop and build a view of each folder as you try to get deeper in a folder structure or find one file in a folder of a thousand documents.

This can take an annoying amount of time.

22. For the same reason as in step 20., if you have a large amount of programs on your Programs part of the Start Menu, break them up into categories. Put often used programs and folders on the initial Start Menu.

Start menu screenshot

It's easiest to work with Explorer when you want to manipulate the Start Menu. In fact if you right click on the Start Menu and choose "Explore," it will open most likely open right to the Start Menu Folder in you you C:\ Drive File Tree.

23. Switch from the new XP Start Menu to the Classic View.

Choose the Start Button -> Settings ->
Taskbar and Settings -> Start Menu Tab
-> Classic Start menu

Start Menu options screenshot

The Classic View packs information (actually program shortcuts) more efficiently.

24. Turn off personalized menus on your Start Menu and in all your MS Office Programs.

Choose the Start Button -> Settings ->
Taskbar and Settings -> Start Menu Tab
-> Classic Start menu -> Customize ->
Uncheck "Use Personalized Menus"

Customize Classic Menus options screenshot

For MS Office Programs:

Right Click -> Choose Customize
-> Choose the Options Tab ->
Check "Always Show Full Menus"

MS Office Menu options screenshot

This is a pet peeve of mine. That is I get annoyed at, not being sure something is on a menu because it is not immediately shown, or having to wait for less used item to appear.

25. If your using dialup, turn off the download of graphics.

Internet Explorer -> Tools Menu
-> Options -> Advanced Tab ->
Scroll Down to Multimedia -> 
Uncheck Show Pictures

Internet options Advanced Tab screenshot

Toggle images icon on IE toolbar

ImageToggler for IE 5 (works with IE 6 too - it's
part of the Web Accessories for Internet Explorer 5 - it installs a shortcut on the Links Toolbar in IE)

To Display the Enact the Image
Toggler After Installation:

Choose View Menu in IE -> Toolbars
-> Check Links-> Go to the Links 
Toolbar. Select "Toggle Images.exe," 
which should be the last item
