File Association Helper in Startup

from another forum on May 6, 2018:
You can uninstall File Association Helper in less than 5 minutes. Here are the steps to follow:

Step 1 — Uninstall File Association Helper via Control Panel

Simply go to Start > type Control Panel > double click the first result to launch Control Panel.
Then go to Uninstall a program > locate File Association Helper in the list and select it
Select Uninstall > wait until Windows completely removes FAH from your PC.
Restart your PC.
Step 2 — Clean the Registry Editor

Now that you removed the program, you also need to remove any traces or file changes associated with it. To do that, you need to open the Registry Editor.

Go to Start > type “regedit” > launch the Registry Editor
Locate the following keys and delete them:
KEY_CURRENT_USERSoftwareFile Association Helper
HKEY_LOCAL_MACHINESoftwareFile Association Helper

Step 3 — Check all the hidden files and folders

File Association Helper may have left behind various hidden files and folders. In order to completely remove the software, you can also need to delete these files. Here’s how to do that:

The final step is to clean the Temp folder where all the temporary files are stored. To empty the folder, go to Start and type the %temp% command.

This will open the Temp folders. You can now empty them. If the system displays an error message when deleting some files, leave them. The files might be in use by Windows services or some running software.

Step 5 — Use a dedicated tool to remove software leftovers

After you performed all the steps listed above, you have removed 99.9% of all the files and folders left behind by File Association Helper. However, there may be a few file that escaped your scrutiny. In order to make sure that you have removed all of them, you can also use a dedicated software uninstaller.

These applications are specially designed to remove the selected application along with all of its files and registry entries. As a result, the application will be completely removed from your PC.

There are many great uninstaller tools available on the market, but the best are IOBit Uninstaller and Revo Uninstaller so feel free to try any of these tools.

 

Windows Troubleshooters don't have an associated app

Hi, thanks for the reply.

I am aware that MSDT is deprecated, as it shows a large colored box saying so when running the program.

I was able to launch the troubleshooters via the commandlines you provided. But as I'm sure you're aware, these will launch using MSDT. And unless I'm misunderstanding something, this will only be a temporary fix until 2025, when MSDT will be completely removed as a whole.

I'm looking for a more permanent fix. As of now I'm still unable to run any of the listed troubleshooters (excluding MSDT) within the settings app, as it spits out the error saying the troubleshooters don't have an associated app to run.

It would be a big help if I knew what the associated app is for troubleshooters.

I can only assume the associated app is 'ms-contact-support'. But that doesn't seem to bring up anything of note when I search it up. The only other app I can think of is the settings app itself, but I think that should've been picked up by the sfc scan if it was the culprit.

Any other ideas?
