Every program you install (or uninstall) in your computer, modifies the registry. The registry is a vast library of system settings - settings that can sometimes lead to blue screens and other instabilities. Even when programs are uninstalled, their registry settings can stay behind.

The settings are useless to the daily operation of your PC, but they can cause conflicts and errors. Your computer continues scanning these error-ridden registry entries, thus slowing everything down. As a result of this, your computer crashes.

Cleaning the registry manually is not an easy task. Luckily, software which can clean the registry instead of you and fix a slow computer do exist.

Ccleaner - for Windows users or Ccleaner for Mac users is one of the best for this task. Other software include Advanced SystemCare (MacBooster - Mac OS), Wise Cleaner (Windows only) etc.

All you have to do is to install one of them, follow the user-friendly instructions and leave the rest to them. Make sure to scan your computer regularly (at least once per week).

Every activity you do on your computer leaves residues. The residues such as browsing history, temporary files, etc. accumulate and the computer becomes slower. Even though they are made to make operations faster, if they become corrupt, they turn out to do quite the opposite. In order for you to improve the computer's speed and performance, you need to do a system cleanup.

Windows offers a utility known as Disk Cleanup. To run this tool, follow the steps below:

1. Go to Start menu and type Disk Cleanup in the start menu search box;
2. Select the drive you want to clean up first by clicking the small arrow and click OK;
   
   

   
   
   

3. Under Files to delete, select the file types to get rid of (by ticking the checkboxes next to them) and click on OK.
   *Repeat this for each drive separately ( "C:" "D:" "E:" and etc.).

   
   

   

Everything we do on your computers leaves residues known as temp files. A small amount of temp files won't do harm. However, a greater amount of temp files can slow down the computer.

Cleaning temp files manually is not an easy task, as it's hard to tell what can be deleted, and what not. This is why it's best to download and install dedicated software like CCleaner, Advanced Systemcare (which are one of the best for the task, according to users), and scan and clean your computer on a weekly basis.

Everything you do on your computer leaves residues known as temp files. A small amount of temp files doesn't pose a threat. However, a greater amount of temp files can slow down your computer.

Mac OS tries to clean them by itself. However, a dedicated application like CCleaner for Mac, MacBooster (which have a user-friendly interface which are one of the best, according to users), will be more efficient. Make sure to clean the temp files on a weekly basis.

One of the reasons why computer is slow may be the amount of fragmented files. When you install and uninstall applications or when you move files, you leave behind leftovers known as fragmented files. Fragmented files can slow your computer down if they aren't taken care of.

Windows has an easy-to-use built-in utility that defragments your hard drive, called Disk Defragmenter.

If you use a hard disk drive, to run the utility, follow the steps below:

1. Open the start menu and type Disk Defragmenter or Defragment and Optimize Drives;
2. Right-click it and Run as Administrator;
3. Select the partition you want to defragment (Local Disk "C:" ; "D:" etc.);
4. Click on Defragment Disk and wait until the defragmenting process is completed.
5. Make sure to defragment all the drives on your computer ( "C:" "D:" "E:" and etc.) at least once per month.
   
   

Note: If you are using SSD (Solid-state Drive) DO NOT DEFRAGMENT IT, because if you do, you might damage it. SSDs store data in a sequential order (as opposed to random order).

Also, don't defragment the System Reserved partition, because it is meant only for system files, which are important for the computer.
