Uninstall just has to do these procedures after starting the software uninstallation

A small partner asked Xiao Bian why he was not using third-party software when he was obsessed with using the registry, group policies, etc. to modify the system and could use the system's own features. This problem is obvious. For so many years, which ones are safe and auxiliary tools that are not "barrel" products? During the installation process, there is a pile of other software. And even if you don't want to use it, will you be completely clean after uninstalling it?

No matter which software will leave its own shadow in Windows when uninstalling, which is the so-called system residue, and these residues are deeply engraved in the registry inside Oh, foreign software is better, that is, a few Running or related projects, and some software injections are the opportunity to automatically download the reinstalled component-level applications, who dares to use?

What? Xiao Bian is an alarmist? We can use this way to experiment, perform different software "install - uninstall" operation, see if Windows has not slowed down in the boot, shutdown or running speed, then open the registry editor and see

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

How many folders do you have?

Some of these folders are uninstallation tools for existing applications, and some of them have been left in the registry. How to tell? Pay attention to the numeric data information of the “DisplayName”, “InstallLocation”, and “InstallSource” keys on the right side, and then think back to the previous uninstalled software name. If the information is correct, the whole folder will be deleted even if it is completely cleaned up. .

In addition, "InstallLocation" shows the location where the software is installed. We also need to check whether this folder is still left after the installation of the application software. It is considered that the software will be completely "unloaded" when it is dried up together!
