Windows 10: Odd entry in Programs list

Just got the Oct 2020 update installed on WIn10 Home. Have an unusual reg key-looking entry in programs list:





Clicking on details shows:





Never seen this type of entry in Programs before. Any idea what it might be? Cannot uninstall via Windows settings/apps uninstall button grayed out but could remove with IOBit Uninstaller.

:)

 

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.

 

Odd bug: strange entry in the list of installed apps

I noticed earlier today a strange entry in my list of installed apps/programs in the state menu. All it says is TrayItem followed by a list of characters. You can see it in the image below. I am not sure why its there, but I do know when it appeared. It showed up after I ran into an issue with the system clock. I didn't notice til this morning that it thought the time zone was Pacific Time. After changing it to eastern and putting it on the right hour, I thought everything was fixed until later I realized it was actually ahead by 12 hours, so I had to change the time to pm from am, and the date back an hour. The action center then kept telling me I had to login again but wasn't giving me an option to do so. Restarting didn't help, and I eventually found a solution online which required switching to a local account and back to back to my Microsoft account. After doing this, the TrayItem appeared but the error went away, and I haven't had any other issues since. I just find the entry being there annoying and want to know if anyone knows how to get rid of it. I've tried opening it, and uninstalling it, but neither of those actually did anything. Is there maybe a registry key that needs to be messed with?

 

Programs not working

In post 26 there were steps listed to fix the operating system corruption.
Are you able to follow them?
In post 29 was the suggested dism repair command.
