What Is System32?
The System32 folder was first introduced since Windows 2000. It is a required Microsoft Windows system directory that is located in either C:\Windows\System32 or C:\Winnt\system32.
What Is in System32?
The System32 folder contains many important system files that can maintain the normal function of Windows. What kinds of files are stored in it? You can access the directory to have a look.
The following screenshot is an example. You can see that the .dll and .exe files are the main contents in the System32 folder. Of course, there are some other things in it like Control Panel applets, MS-DOS applications, DAT files, and more.
For instance, when you open Command Prompt, you are really running cmd.exe from the System32 directory. You can also run other programs from this folder like Control Panel, Disk Management, Calculator, PowerShell, Task Manager, and more.
Some third-party programs can also put files into the System32 folder like the Dropbox service DbxSvc.exe.
Additionally, you may note that there are some subfolders in System32. They contain config that holds numerous Windows Registry files, drivers and oobe for Windows activation files.

After deleting some files in the System32 folder, Windows began to fall apart. Some functions couldn’t work. For instance, Task Manager was not working and we couldn’t enter the Settings app.
We even couldn’t shut down the computer normally because when pressing the Start button, nothing happened. So, we had to force close the computer.
When trying to boot the computer again, Windows started an automatic repair process and then entered a blue screen saying Automatic Repair couldn’t repair your PC. We tried Advanced options and it also failed.
