Install programs
When installing a program, you should avoid terminating the installation in an improper way (such as a power break) because it might cause system errors or even system boot failure.
Uninstall programs
If you want to uninstall a program, you should never directly delete the files or directories that have been installed. This is harmful to the system and could cause system crashes. Please follow the instructions below to correctly uninstall the software. (Make sure to backup the relevant documents and system settings before uninstalling the program.)
Step 1
If the program has an uninstall function, just run its uninstall program.
Step 2
If the program does not contain the uninstall function, click “Start” and select “Control Panel”.
