Unused File Extension keeps reappearing after 'Add to Exclude list' ?

Unused File Extension urn:content-classes:wizard/addcontentclass HKCR\urn:content-classes:wizard/addcontentclass

Continually appears after registry scan, always right-click and add to 'Add to Exclude list', and again reappears.

No big deal, just curious why this particular unused file extension keeps reappearing after add to exclude list ?

add the extension to your exclude list

Thank you for the reply.

Followed your link/s.

The unused file extension shows up on the Options/Exclude list, but it also keeps showing up on all registry scans after 'excluded' per image attached.

Like said, no big deal, will just ignore the occurence, just thought it was a wierd thing to happen when using Ccleaner.

Those will show up, always after applying the monthly Microsoft Updates on my system. I personally let CCleaner nuke them without having any issues (as of yet).

Thanks for the info.

Actually, the same UFEs show up the next time I scan, within minutes of the 1st scan when they were 'excluded'.

They must regenerate themselves automatically or something ?

Guess will just wait and see :rolleyes:

Since they keep showing up almost immediately after you clean them you're probably using a software that adds them back in - which is a good thing if they're actually needed.
