My computer will automatically install some messy programs when it is turned on! What is the reason?

This is not your problem, but people who use computers a lot will have such problems. There are some advantages in this (I won't go into details here), so the company that develops the software will do whatever it takes to hide some plug-ins in the upgraded software or installation package. Plug-ins are the source of pop-up advertisements.

1. First, press the shortcut key Win+R to open the running window and enter GPEDIT. MSC, and then click ok. This string is used to open the local group policy editor.

2. Then enter the window of local group policy editor, click Computer Configuration-Management Template -Windows Component on the left, and find Windows Installer on the right.

3. Then double-click the Windows Installer option and slide the mouse down on the right side to find the option that prohibits users from installing. Next, we need to open it so that the installation can be prohibited.

4. Finally, double-click to open the window that prohibits users from installing, and change unconfigured to enabled. After the user installation behavior below, select Hide User Installation, and don't forget to click OK.
