I've had Win 11 for a year-ish, but it only very recently pushed the 22H2 update for me. After updating the system to 22H2, in the "Open With" programs list there's this program that only displays as "\" and trying to click on it just pops up the "choose app to open image with" menu again.
I'm assuming it's a program that I already uninstalled or something? Or a weird directory muck-up.
I've already cleared the registry and this unknown program is still listed. And this mystery program only appears in the recommended list if I try to open JPG, PNG, and TIF images. It does not show up for GIF or WebP images.
So far it has not caused any issues for me, it just looks weird and I don't want this to be there.
At the Command Prompt (as Admin) execute "assoc" and "ftype" individually.
Each will likely produce a lengthy output.
Begin with "assoc".
Examine the area to the right of the = sign, noting any application names.
Check for unfamiliar entries that weren’t installed or are known to have been uninstalled/removed.
Repeat the process with "ftype".
The details here are more comprehensive, but you might notice something unusual.
It’s possible another method exists, though I haven’t explored it extensively. TBD.
I ran the CMD commands and noticed empty spots in the "Quicktime" list for ftype. I believe this relates to the problem, as the image file types with those missing entries match the ones where the "\" program appears.
QuickTime - possibly Apple's media player.
Did you manage to install it (Windows version) or another media player?
As I see it, Apple no longer backs QuickTime for Windows.
What changes were made in the registry?
If you look through the Registry for "Quicktime" or just "Quick", do you find any entries?
Search only.
Registry modifications should be a last resort; it's better to be cautious with further changes until more information is available.
