OneCare Live startup Screen

The taskbar icon of OneCare Live. Green indicates that there is no problem at all. Yellow indicates that there is a problem, but it is not so important. You can ignore it temporarily. The red color indicates that it is serious. If you do not need to deal with it urgently, you will be suspended if you cannot locate it.

OneCare tune-up

OneCare's defragment speed is relatively high, which is much faster than XP and the disk fragment tools attached to earlier windows. Among them, remove unnecessary files from your computer is a new function. Many unnecessary backups can be deleted through this function. Microsoft also gives a saying: Which backups can be deleted and which backups cannot be deleted. However, during use, defragment is not actually 100% complete, and update cannot be connected. How to update it is explained in helpcenter.
