Malicious Software Removal Tool in Win10 Home won't run

RikDatta,

Looks to me like you have May 2017 Software Removal Tool installed three times.  As I previously stated, my update history shows that May 2017 KB890830 installed automatically twice on two different dates.

My suspicion is that it doesn't like being installed again three times.  This is conjecture though.  

Possible solutions might be:

1.  Restore to a earlier point in time in Recovery (should you have good fairly recent restore points).

2.  Uninstall the latest of the three KB890830 for May 2017.  The uninstall option is at the top of your Update History.

if you would have checked and read over the info at the link that I supplied in my first reply you would have seen this:

"The Malicious Software Removal Tool does not use an installer. Typically, when you run the Malicious Software Removal Tool, it creates a randomly named temporary directory on the root drive of the computer. This directory contains several files, and it includes the Mrtstub.exe file. Most of the time, this folder is automatically deleted after the tool finishes running or after the next time that you start the computer. However, this folder may not always be automatically deleted. In these cases, you can manually delete this folder, and this has no adverse effect on the computer."

Hi.

Please see the attached image.

So, if it was installed, where can I find it?

RikDatta,

Yes, as Richard stated, check your update history in Windows Update.....scroll to the bottom for "Other Updates" and determine how many times KB890830 was installed. 

My update history shows it was installed twice on my OS with the identical KB #.  Does yours show installation three times or just two?

The last update was this one:

2017-05 Cumulative Update for Windows 10 Version 1703 for x64-based Systems (KB4020102)

Successfully installed on Thu 01 06 2017

When I check for updates, it says that my system is up to date.
