The System32 folder is located in the Windows folder and contains important information and configurations that are basic to the operating system. The folder contains important”.dll” and”.exe” files. Many errors that are seen on computers have the word “System32” in them, but this does not mean that the System32 folder triggers them, these errors occur when important files are missing or damaged.

This can be caused by an empty entry, which can be left behind, for example by an incomplete deletion of the program, in the file.

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run and/or
HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Run keys.

Recently, many users have reported that when the computer starts up, the System32 folder in the file explorer opens automatically. In this article, we will inform you of the reason for this problem and propose practical solutions to solve it.

The System32 folder opens at startup due to a corrupted registry value. The value may have been corrupted for a number of reasons, including malware or the installation/uninstallation of a program that has not been installed or uninstalled properly.

The problem can also be caused by empty runtime entries in your boot shortcuts that open the system32 folder. The first thing you need to do is to check the registry entries of the start run with AutoRuns and, if present, delete these entries.

Check the startup folder

If the Explorer Libraries folder appears each time you restart, the first location you want to check is the Start folder. Go to Start, All Programs, then click Start. If there is a shortcut to the Libraries folder, delete it.

    Important When you execute this command, DISM uses Windows Update to provide the files needed to troubleshoot errors. However, if your Windows Update client is already down, use a running Windows installation as a repair source or a Windows folder side by side from a network share or removable disk, such as the Windows DVD, as the source for the files. To do this, execute the following command instead:
    DISM.exe /Online /Cleanup Image /RestoreHealth /Source:C:\RepairSource\Windows /LimitAccess
  6. Type the following command and press Enter.
  7. It may take several minutes for the command operation to end.
    sfc /scannow
