Help with 0x80073cf9 on Windows 10

Hi Jon,

I do appreciate your time and efforts.

Do not worry, will assist you with the issue.

Restart the computer and check. Also, check for Windows updates.

Run the troubleshooter for Windows apps:

http://windows.microsoft.com/en-us/windows-10/run-the-troubleshooter-for-windows-apps

Check for updates for apps from Windows Store and install if you find any.

Try to run the following commands and check if it helps.

1.  Type CMD in Search. Right click on it to run as an administrator.

2. Type the following 4 commands at the CMD prompt:

WSReset.exe.

dism /online /cleanup-image /restorehealth

sfc /scannow

powershell

Get-AppXPackage -AllUsers |Where-Object {$_.InstallLocation -like "*SystemApps*"} | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

1. Close the CMD window.

2. Check to see if the issue is resolved. If not, restart the PC.

Use the System File Checker tool to repair missing or corrupted system files:

Hope this helps in resolving the issue. If the issue persists, do get back to us. We will be happy to assist you.

Ok I tried what you suggested. Unfortunately some of it can't be completed because the Windows Store won't open since I installed the latest Windows Update. The app troubleshooter did not find any issues, the dism completed successfully, the System File Checker came back clean.  I did notice when I ran the powershell  script it came up with a lot of error messages which mainly said deployment failed with HRESULT:  0x80073cf9.

I am attaching a screen shot of the result:

SO as it stands, I can't verify whether this helped or not because of the Windows Store not opening now, but based on the results above I am thinking when I do get Store working again I will still have same problem.

Well I got the store to open again, redid the steps above. Same results. Apps are not downloading.

I have been dealing with this issue for some time as well on windows 10 with no resolve.  Tonight I figured I would try to come at this with a different approach.  Seems as thought the problem we are seeing is more related to patching of the user environment.  Please try these steps and see if this resolves your issue.

1. Create a additional local account on the computer.  Make this account a system administrator using the Settings > Accounts >Family & Other Users > Other Users > "Add someone else to this PC" > "I don't have this persons sign-in information". Fill in the information.  Once the information is complete you will find the user name under the "Other Users" fold on the Accounts page.  Click on this user and make sure they are identified as Administrator - Local account. (If not this can be done by clicking the Change account type and accepting the change.

2. Once the user is created, switch over to this user. You will see many of the store apps work in this profile.  I feel that is where the problem is occurring.  Your user profile is corrupted due to a update.  If this did not work for you, well... I am sorry, back to the drawing board. (You can stop at this point)

3. What this means is you will now have to re-create you profile, sign out as this "test user" and sign back in as you.  Spend the time to backup all your files/profile settings from the C:\Users\{username} folder. (You don't want to loose your files by proceeding without precaution.)

4. Once this step is complete, reboot the machine and log in as the "test user".  This will allow you to access your previous profile and remove it.  If it doesn't matter to you, you can also use this "test user".  Once in as the Test user, proceed to Settings > Accounts >Family & other users > Other users > click on the old account and click on Remove.  This will remove your old account! Make sure your ok with this.  Now that the account is removed, you can add the new account using the "Add someone else to this PC.  You should even be able to add the old account name.  This should resolve your issue.

I am glad I did this and not re-installed Windows, that would have been a mess.  I hope this helps everyone out there that might be pulling out their hair!

I do not understand why Microsoft cannot get store app right.

This is my second time to deal with this issue. Last time, I had to chat with a MS tech support and ended up reinstall Windows 10. The problem came back again.

I tried almost everything I can find on the Internet and it takes a lot of time.

run troubleshooter for apps (which did not complain anything)

wsreset, which some times gives an error saying ms-windows-store:PurgeCaches failed and did not solve the problem if it silently finished.

powershell commands, which gave tons of error messages that probably even the MS developers had hard time understanding them.

change the permissions of folders

try with a new account

rename \windows\softwaredistribution

sfc complains about some log files, but could not fix them.

Why cannot Microsoft check all these in troubleshooter?

OK. I did update with the media tool on Windows 10 upgrade pages.

The problems were still there.

Then I run wsreset several times until no error messages were reported.

Then I run the powershell command in earlier posts several times until only a few error messages (either higher version or resources being used).

Reboot the computer and I can see all App icons. However, all apps just cannot start. I saw a window opened and then closed immediately.

Create a new user. Have the same problems in the new account.

Try to run wsreset again and got this error message:

ms-windowstore-purchcache:

Windows cannot access the specified device, path, or file

Now I suspect it is the file permission problems, but do not know which folder.

Only a couple of days after a clean installation, I cannot launch store app again. It works on another account. Really frustrated.

I am still having this issue. I found out it has something to do with applocker but still stuck witch the problem.
