I suggest that you go to official website to download the update patch when updating, because there are hundreds of meters of patches left in each automatic update. Now you have to go to official website to download the update manually. In addition, you can delete QQ audio and video QQ toolbar QQ computer housekeeper Tencent TT browser and other mandatory bundled installation packages under the Hyun Dance bin directory, which can at least save 100m space.

The above is my own solution.

It is worth noting that when we right-click the disk, there is a compressed drive. Remember, do not compress. If you compress the disk, you can't start the computer when you restart it later, so you can only redo the system. This is my personal experience.
