Windows 10: Windows AppInstaller interfering app startup

So I am currently using Arc as my default browser and it gives me a consistent issue. Every time i try to start the browser or even try to open some documentwhile the browser is already active the app installer pops up and tried to check for updates and says "hang on while we get your app's information".Now this popup does not stops me from using it , as this process ends after anywhere between 5-50 seconds. But the thing is that I have never seen such an issue , neither has anyone on the internetas far as I have seen.[I am attaching the screenshot of process window]Now I tried updating al

Can't get GPU-Z to start with Windows 8.1 startup

I'm not sure how to do that. Could you list the steps for a noob?

 

Adding programs to startup with Windows 7?

You could add entries to the registry to launch the apps on startup, but it's easier to just add them to the startup foler as Newt suggested.

 

Appinstaller cannot install msix package depending on windows version

Our Appinstaller which downloads an msix through a URI gives the following error on certain windows version:

The MSIX is published on a static web page hosted in IIS on a Windows Server 2019 version 1809 - OS Build 17763.5576.

Some tests on different OS/Build version on the "clients" give the following results

• Windows 10 21H2 - OS Build 19044.1288: appinstaller works
  
• Windows 10 22H2 - OS Build 19045.2006: appinstaller works
  
• Windows 10 22H2 - OS Build 19045.4046: appinstaller does not work
  
• Windows 10 22H2 - OS Build 19045.4170: appinstaller does not work
  

When testing on a Windows server version with a lower OS Build (17763.4851), the appinstaller does work on all Windows 10 builds.

Also installing the MSIX itself (without Appinstaller and the auto update feature) also woks on on all Windows 10 builds.

It seems the problem depends on a combination of the Windows 10 and Windows Server 2019 build version.

When googling on the errorcode 0x80072F8F, you will find many different causes, but nothing that can explain why one Aappinstaller works on the same Windows machine and the other does not. I have tested/verified the most common problems

• No issues with not-synced time zones
  
• Windows store restore
  
• Certificate issues: tried hosting the appinstaller/msix package on the static web page unsecure and updated the uri's in the appinstaller to http.
  

Some more information about the error itself.

Tried installing it via powershell

Anyone has any idea what might cause this behavior?
