Clean up the right-click list to make Windows 7 faster

When we use the computer, it is inevitable to install and uninstall the program. This is very easy to produce garbage and damaged files. After the installation, there are often many programs in our right mouse button menu. Too many programs have a great impact on the running speed of the system.

I believe we should be very clear through this picture. So how do these extra things come about, how can we reduce the speed of the system better? Let me explain this with a video player as an example.
First let us enter the registry. Click Start under Run Input “regedit”, then navigate to HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\FileExts\\.avi\\OpenWithList. The window on the right is the player you have or has installed, now It's fine to delete the open connection file you don't want.





Edit Comment:
I understand that the registry has a great impact on the system, so we try to keep it under control. The registry is clean, which is very helpful for the speed of the computer
