It's best if we break things down into two sections, the first are those that should be done regularly, the next are those that only need to be done once, or very infequently.
First, the tasks that need to be carried out regularly
- Clear out your Temporary files
During the normal operation of your computer, Windows and your other programs create an awful lot of temporary files. For the most part they are just that, temporary. But for any number of reasons, when they're no longer needed they don't get removed by the program that created them. So over time their number builds up, and unless you clear them out they can slow down your computer noticeably.
In the case of your browser, the problem can be worse. All browsers cache the web pages you visit. The original reason was to make loading pages faster. When everyone was on dial-up this was quite a good idea, but with modern fast connections it's mostly unnecessary now. However browsers still cache webpages, and unless cleaned out regularly they build up to a position where they can have some pretty dramatic effects on how your browser works. Any number of wierd browser problems are caused by nothing more than an overfull cache.
So once a month, or once a week if you're a heavy user, it's a good idea to clean out your Temporary files.

For users of Vista
- Click Start > All Programs > Accessories > System Tools > Disk Cleanup
- This will open the Disk Cleanup Options window
- Choose:
- My files only
or - Files from all users on this computer
- My files only
- Click Continue
- Select the drive you want to clean up
- Click OK
- Check the following entries:
- Temporary Internet Files
- Recycle Bin
- Temporary Files
- Click OK
- When asked if you're sure you want to delete these files, click Yes.
- Defrag your hard drive
Every time you write a file to your hard drive, the drive controller has to find space on your drive. It will often break files into fragments, so that it can use the available disk space efficiently. However over time files can become very fragmented because of this, and your drive controller has to work harder to find all the fragments and re-combine them so that a program can use it. This slows things down, depending on the amount of fragmentation of your files, it can slow things down a lot.
So once a month (for heavy users), or once every 3 or 4 months (for light users), it's a good idea to defragment your hard drive.
This will re-arrange the fragments on your drive so they form contiguous entities which are much easier for your drive controller to deal with.
It's a time consuming operation, usually taking several hours, so best to do what I do, and start it going before you go to bed.
Quote:For users of XP
- Click Start > All Programs > Accessories > System Tools > Disk Defragmenter
- Click on the Analyze button.
- Let the analyzer run, it takes 5-10 minutes or so, sometimes longer, depending on your disk size.
- When finished it will pop up a window telling you whether you need to defrag or not.
- Microsoft is notoriously conservative about defragging, so don't take the recommendation you get as gospel. Have a look at the graph produced when analyzing, if there's more than about 10-15% showing red, then Defragging will improve your disk performance.
- If you need to defrag:
- Click the Defragment button.
- The defrag process can take hours, so go do something useful, or if you've followed my advice and done this before bedtime, go have a good sleep and it'll be done when you wake up.
For users of Vista
- Click Start > All Programs > Accessories > System Tools > Disk Defragmenter
- Click Continue
- A window will open
- To set up a regular schedule to defragment your hard drive
- Check Run on a schedule (recommended)
- Select the time of day and day of the week that works best for you
- Select the volume (drive) to be defragmented
- To defragment right now:
- Click on the Defragment Now button
- Select drives to defragment
- Click OK to begin the defragmentation process
Next, the ones that you only need to do once or very infrequently.
- Reduce the number of program that are Auto Starting
Pretty much every program you install these days is set to auto start when you boot up. The program manufacturers tell you it's for your benefit, but the truth is for most of them it's just not necessary that they do so. Lots of auto starting program will severely slow down your startup time, and having lots of unnecessary program running in memory will slow down the running speed of your computer as well.
Luckily it's not hard to prevent unecessary program from auto starting. Doing so does not mean you can't use the program, you start them by double clicking on their icons, just as you always have, it just means they won't be running when you're not using them.
Of course program like your firewall and antivirus need to auto run, so we won't be touching them at all.
Quote:For inexperienced computer users.
- Download StartupLite by Rubberducky to your desktop.
- Doubleclick StartupLite.exe to launch the program.
- Ensure the Disable box is checked.
- Click Continue.
- A pop up message will tell you the unnecessary startup items in your list have been disabled and ask you to restart your computer.
- Re-start your computer.
Quote:For experienced users,
- Download and install WinPatrol By Bill Pytlovany.
- Doubleclick the Scottydog icon in your taskbar to launch the program.
- Click on the Startup Programs tab.
- To stop a program starting automatically at startup, click on it to highlight it, then click the Disablebutton.
(It will be up to you to research items first to see whether they should be disabled) - Exit WinPatrol.
If you've disabled something you later wish to re-enable, do the following.
- Launch WinPatrol (as described above).
- Click on the Startup Programs tab.
- Click on entry you wish to re-enable.
- With a disabled entry, the Disable button will turn into an Enable button.
- Click Enable
- Exit WinPatrol
- Do you have a HOSTS file installed?
If you are using one of the pre-prepared Hosts files to block unwanted and dangerous sites (eg. MVPs Hosts or Bluetack) then if you are not part of a domain, and notice a slowdown, you will need to disable the Windows DNS Client Service.
Quote:For users of XP,
- Click Start > Run > type services.msc into the Open: box, then click OK.
- This will open the Services window.
- Scroll down to DNS Client and double click on it.
- Click the Stop button to stop the service.
- Set startup type to Manual.
- Click OK
- Exit the Services window.
For users of Vista, - From Start, in the Start Search box, type services.msc
- Give permission to continue.
- Scroll down to DNS Client and double click on it.
- Under Service Status, click Stop
- Under Startup Type, choose Disabled.
- Click Apply, OK
- Exit the Services window.
- Disable your Indexing Service
This service does what its name suggests, it indexes all your files, in order that you can find things faster when searching.
It does it on a continuous basis, using up a great deal of CPU time and working your hard drive for no real good reason. As a result, although it may speed up your search times, it slows down your computer at all other times.
I don't know about you, but I know where most of the files I want are located. For the number of times I have to run a search I'd rather have a faster computer than a faster search, so I turn this one off.
By default this service is not installed in Vista, if you see it on your Vista then it has been deliberately added for reverse compatibility reasons, leave it alone.
Quote:For users of XP,
- Click Start > Run > type services.msc into the Open: box, then click OK.
- This will open the Services window.
- Scroll down to Indexing Service and double click on it.
- Click the Stop button to stop the service.
- Set Startup type to Disabled.
- Click OK
- Exit the Services window.
- Check the amount of free space you have on your hard drive
Windows (XP and Vista) needs a certain amount of "overhead" (free disk space) if it's to operate efficiently. If it doesn't have that space, your processor has to "page out", which will slow everything down considerably.
Ideally you need at least 15-20% of your disk to be empty, if you don't have 15% then it's time to start freeing up some disk space.
Quote:For users of XP,
- Click Start > All Programs > Accessories > System Tools > Disk Defragmenter
- Look in the last column (top right) under % Free Space
- Exit Disk Defragmenter.
For users of Vista, - Click Start > Computer
- A window will open
- Information for your hard disk drive(s), including the exact amount of free space available, will be displayed in the uppermost portion of the window.
- Presuming you don't have enough free disk space, here's a couple of suggestions for freeing some up
- Remove unnecessary programs
OK, time to be honest with yourself, are you really using all those programs you've got installed, or are there some that you haven't used in a lifetime. If there are, then why not get rid of them and free up some disk space. Your hard drive will thank you for your efforts.
Quote:For users of XP,
- Click Start > Control Panel > Add or Remove Programs
- Click on the program you want to remove to highlight it.
- Click the Change/Remove button and follow any instructions given.
- Repeat for all program you wish to remove.
For users of Vista,
- For Control Panel Home view - Click Start > Control Panel > Programs > Programs and Features
- For Classic View - Click Start > Control Panel > Programs and Features
[list] - For either option, to uninstall a program, select it from the list and then click Uninstall.
- Remove unnecessary programs
- Reduce your System Restore Points
Windows creates System Restore points on a regular basis (every 24 hours), they take up a great deal of space on your hard drive (up to 12% for XP, 15% for Vista). If your computer has been running without problems (other than the slowness) for some time, then you can free up a lot of space by reducing the number of System Restore points to one (the latest).
Windows will continue creating more RPs, but it'll take some time before you need to thin them out again.
Quote:For users of XP,
- Click Start > All Programs > Accessories > System Tools > Disk Cleanup
- This will bring up the Disk Cleanup window.
- Click the More Options tab.
- In the System Restore field, click Clean up
- You will be prompted if you want to remove all but the most recent restore point.
- Click Yes.
- Click OK.
- When prompted whether you're sure you want to do this click Yes.
For users of Vista,
- Click Start > All Programs > System Tools > Disk Cleanup
- Select Files from all users on this computer
- Click on Continue
- Select the appropriate drive letter (usually C:)
- When the Disk Cleanup window opens, select the More Options tab
- Under System Restore and Shadow Copies click on the Clean up button
- All but the latest restore point will be removed
[LIST] - Note: In some editions of Windows Vista, the disc might include file shadow copies and older Windows Complete PC Backup images as part of restore points. This information will also be deleted.
