If the tool from Microsoft is applied, but you still cannot remove the program, or some of the recently installed programs are registered in autoload and prevent normal system startup, then you You can try to uninstall the application through Windows Safe Mode. This method is useful in cases where the software developer himself recommends deleting the program in Safe Mode.

What is Safe Mode, all ways to start the system in Safe Mode, the nuances of entering Safe Mode for Windows 10, the differences in actions for previous versions of the OS, Windows 7 and Windows XP are discussed in the corresponding article. As part of the current record, we will not dwell on this in detail.

Well, we entered Safe Mode, open the Programs and Features menu in the Windows Control Panel, find the application that we want to uninstall, click the Delete button and .... we get the following error:

To start the Windows Installer service, you need to make changes to the Windows registry.

  • Run the Run utility by going to Start - All Programs - Standard (in Windows 10 the Run utility is in the System Tools directory), or by holding the Start keys on the keyboard (on some keyboards, it is marked Win) and R
  • In the opened window we drive in the command

    and click on the Enter key

In the registry editor, go to the following branch:


If you will work in a safe mode with loading network drivers, then further actions need to be done on a branch:

Here, on the left side of the registry editor, you need to create another partition, calling it MSIServer

In the created section, in the right part of the registry editor, with the created string parameter (add a new string parameter if it does not appear automatically) in the Value field write Service
