Fix Script Error Window with Google Tag Manager URL

Yesterday when I tried to shutdown my Windows PC, it displayed a script error window with problem at a certain Google tag manager URL. This window had to be dismissed before I could shut down Windows. But the window looked suspicious and I took a screenshot for investigating later.

After half an hour of investigating this matter the next morning, I came to the conclusion that the script error is because of a program that was left behind after the uninstallation of MiniTool Partition Wizard version 12.6. This tiny program “updatechecker.exe” was still running in the background and causing these script errors.

Somehow it is trying to access Google tag manager URL located at This type of URL is used to track the users through Google Analytics.

This is going to close all the running programs related to this software and then overwrite the existing files. After the installation is complete, do not run MiniTool Partition Wizard. But immediately uninstall it from your system which would remove all the related entries and files from your system. You may still have to delete the left behind folder from C:\Program Files.
