1. Your computer must use 1GB or more than 1GB of storage
2. Free up space by checking the download folder of the computer’s browser. (This folder is usually filled with installers, images, and other storage files that have no one uses).
Every time you visit a webpage, your web browser stores or ‘caches’ it as a small file in your Temporary Internet Files folder. Over time, the volume of these files can build up. Periodically clearing out your browser’s cache will help it to work faster when loading pages and reduce the amount of valuable disk space these cached files take up.
In most browsers these settings can be found within the <History> menu, labeled something along the lines of <Clear browsing data> or <Clear cache & cookies>.
3. NB: often brand new PC comes with all kinds of unnecessary applications known as ‘bloatware’. Bloatware can be uninstall or safely removed without affecting the system.
You or someone might have downloaded something horrible which is accompanied by a spyware, malware, adware or a virus onto the computer. This will bring about a lot of pop-ups and browser extensions that insists you visit adult sites.
Many downloadable applications will attempt to add unnecessary toolbars. These toolbars provide their own search box. Find the toolbar name and then <Uninstall>
4. Soon after download, go to Start > Control Panel> Uninstall a program carefully select any unwanted application and then click <Uninstall>
5. Viruses can slow down your computer and cause data loss, while spyware can compromise security by monitoring your activity and collecting information about you. Launch your antivirus software and make sure it's up to date. Then run a full scan of your hard disk.
6. Reduce the startup programs <start>type in the search space<msconfig.exe> and enter <Satartup> uncheck the unwanted startup programs. Then click on <Apply> and then <ok>
7. Note: Window’s Disk Clean-up utility can help boost your computer’s performance by removing temporary files and unnecessary system files:
Click <Start>. In the search box, type <disk clean up> and, from the list of results that appears, click <Disk Clean-up>
8. In the list of <Drives> click the hard disk drive that you want to clean. For most people this will be the <C: drive>. Click <OK>.
9. In the <Disk Clean-up> box, select the type of files that you want to delete and then click <OK> and then click <Delete files>
10. Regularly defragment your PC. When your PC saves a large file to the hard drive, it breaks it into smaller pieces and stores them across several locations. This means the hard drive works slightly slower. Windows 7’s Disk Defragmenter tool, for example, reorganizes this data in a more logical fashion, so your computer performs quicker. Start> Disk Defragmenter> C: drive> Defragment disk
