Windows 10: Quick Access dropdown items disappeared

Hello everyone,
I finally gave up trying various solutions suggested by strangers on the internet and instead ask about my specific problem.
I wasn't doing anything out of the ordinary this morning when I noticed that some, but not all, pinned items in my quick access sidebar have disappeared but were still visible in the folder. Reboot didn't fix that and then I lost a restore point by creating a custom one (apparently I can have only one restore point...).

Then I checked my registry for IsShortcut which was present, so I deleted it and made it again, still nothing.
Then I followed some advice to clear my jump lists the Win7 way (option 3) and ended up with the Quick Access entirely broken.

I can still see all the pinned items in the quick access folder, but it doesn't expand in the sidebar. The arrow right next to the icon is present till I click on it. Then it just disappears.

I am open to any ideas at this point. I use quick access a lot but I'd prefer not to do a factory reset for that. Oh why isn't there a registry/permissions fix tool for Win...
Thank you everyone

Solved: the problem fixed itself after a bunch of random logouts, shutdowns and reboots, sorry to disappoint those with similar issues. Oh and I also removed all the contents of the Quick Access folder and after a few reboots pinned a single library (documents iirc) back

:)

 

Quick Access - "Location is not available"

I solved the problem without following steps 1, 2, and 3. The solution is stupidly simple and it doesn't make any difference as to whether the problem item in the Quick Access list is pinned or unpinned.

1. Create the folder in the same path where Quick Access reported it to be unlocatable. The folder will be empty.

2. Delete the folder you just created. The Quick Access item that WAS listed in Quick Access disappears!!

Note that #2 does not remove or delete the item from Quick Access. It deletes the empty folder you just created *from the machine* (i.e., it goes to the Recycle bin) and as a consequence of the deletion, it disappears from the Quick Access list.

 

Max icons in Quick Access is only 16?

Why is the maximum number of icons I can pin to the Quick Access folder only 16? As soon as I pin a 17th, the 16th item in the folder disappears and I lose the ability to rearrange icons in the Quick Access bar to the left.
