Remove programs you don't need anymore

source : www.microsoft.com

If you installed a program and it wasn't as useful or as fun as you had hoped, it's a good idea to remove it. Every program installed on your computer takes up space, and some programs slow your computer down (even if you don't use them).

To remove a program

1.	Log on to your computer as an administrator. Click Start, and then click Control Panel.
2.	Click Add or Remove Programs.
3.	In the Currently installed programs list, click the program that you want to remove. Then, click Remove or Change/Remove.
4.	Follow the instructions that appear to remove your program. Each program has a different process. Restart your computer if prompted.

Note: There may be programs on your computer that you're not directly using but that are important. (Operating system updates are an example.) If you're not sure what a program does, it's wise not to remove it until you're sure it's something you do not need. Some programs cannot be removed from the Add or Remove Programs window. In this case, antispyware software such as Windows Defender may be able to remove the software.
