user\tester has executed C: \lockdowntool.exe This process attempted to access HKCU\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\POLICIES\SYSTEM\DISABLETASKMGR. iolated the "Disable Registry Editor and Task Manager" rule and was therefore blocked. KB85494 explains how to respond to this event.
Like I always say! There is never a one solution fit all when troubleshooting.
I had a look at the Event Viewer and I found out that a virus scanner (McAfee) was actually blocking this application from running and applying correctly.
Solution: Below are some recommendations to fix this issue.
– Excluded the file from the virus scanner in order to allow the application to execute correctly.
– Or, temporarily disable the Anti-Virus Solution from running from a specific period of time. In this way, the application will be able to apply the desired settings correctly.
