Default Apps won't open or re-install, No Store App since......

Hello Guys,

Sorry to keep bothering you but just when my Win 10 install runs well and I feel safe with it something else goes wrong, following on from my problem in this post Start Menu and Cortana Problems again!!!!, I'll do a brief summary below.

1. Basically Windows 10 is ruining 100% OK, Threshold 2 installed, I use the PC one evening, nothing was installed or changed I shut the PC off when I went to bed, the next day I switch it on I have no start menu or Cortana.

2. Following JDS63's advise I downloaded Win 10 build 10586.3 ISO and executed the following commands:- DISM /Online /Cleanup-Image /RestoreHealth /source:WIM:X:\Sources\Install.wim:1 /LimitAccess
Dism /Online /Cleanup-Image /RestoreHealth
sfc /scannow

errors were found and repaired and all scans ended error free, this did not fix my problem.

3. Next following a URL I executed the following in Admin Powershell prompt:-
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

This fixed my Start menu and Cortana problems but I now have problems with the built in apps.


Now I can open my start menu but most of the built in apps will not open and the faulty app tiles in the start menu are blank with a text description of what it is. Below you can see my mouse has hovered over the Windows Photo app tile and the pop up box says "@Microsoft.Windows.Photos_15.1118.120.10.0_x64_8we", if I click on it nothing will happen.


In my "All Apps" menu all the Apps not working are on the bottom of the list under the "Other" heading, I cannot open the Store App as that does not work at all either. See pic below





One other thing is that when I go into settings and attempt to choose which folders appear on start I can only select "Settings", the other settings are greyed out. I used to select most things in the list, see pic below:-





Does anyone know what I could do to resolve this, is there a different way to restore the built in Apps on the Threshold 2 update, apart from the above my PC is running fine and if I could get my apps back I'd be as happy as Larry.

Thanks for everybody's help

Tony

I've tried running the command in admin Powershell (Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}) and I am getting the following error messages about the version already installed is higher, Could this be something to do with the Threshold 2 update, is there another command I need to use, please find a copy of the powershell text:-

The exact same thing just happened to me after I tried removing and re-installing the Mail app after the Mail live tile froze.

For me, I was unable to get rid of the "@{Microsoft..." apps from 'Other' and like you no apps would run (just a blue app screen with the @{Microsoft. names before closing again).

I just re-installed Windows 10 from a 10586 ISO I already had burnt to DVD. Maybe a bit of a sledge hammer approach, but I figured that was quicker than messing around with it and just done something else for an hour whilst it re-installed Windows. NB: Using 'Keep Personal Files, Apps and Windows Settings' is fine when it asks what you want to keep. It will still put the apps back to normal, you don't need to do a full on wipe.

I tried to do this but I ended up with a directory error - I'm guessing that it's because I upgraded from Win 7 Pro. Running the Powershell command (as admin) that Tonymarcus posted above (#3) gives me the exact same message.

If nobody has found a workaround by Friday, I'll be using my recovery USB to create a clean install.

Try these suggestions I got from a similar post on the Microsoft forums:-

Method 1: I would suggest you to run the below Windows Store apps troubleshooter and check if it helps.
http://windows.microsoft.com/en-us/w...r-windows-apps
If the issues still persist, refer to the below method.

Method 2: I suggest you to reset the Windows Store component and check if it helps.
1. Press Windows Key and R Key.
2. Type “wsreset.exe” without the quotes and hit on Enter Key.
If the issues still persist, refer to the below method.

Method 3: I would suggest you refer to the suggestion provided by Rohit Siddegowda replied on October 9, 2015 in the below link and check if it helps.

Microsoft support are helping me on this thread http://answers.microsoft.com/en-us/w...e-be5d3efe67ac so it might be worth holding on a while, you could chip in the thread with your experience then they might bloody do some about all this start menu problems

Grin said:

Thanks Tony, I had already tried Method 1 and 2 before coming here.
Method 3 does restore the missing icons from the apps that don't show up under Other>@Microsoft<AppName but does not restore the missing apps.

The wsreset gives the message "You'll need a new app to open this MS-Microsoft Store".

I've had great success at work upgrading from both Windows 7 and 8.1 Pro to Win 10 Pro / Enterprise without any problems at all. Out of 21 computers, my home machine is the only one that has given me problems.

edit: More info

I created another user, gave them administrative rights and then logged on as that user. There were several apps that showed "A great app is on the way" and "Pending". A search through available apps showed that the Store, Xbox games, Mail, and PinballFX2 are all missing. Weather, News, Sports, Twitter, and most of the LIve tiles are all working. I fear that in my case, I'm going to have to go through with the clean installation.

You could try in-place upgrade before clean install. This has fixed similar app issues for me Repair Install Windows 10 with an In-place Upgrade - Windows 10 Forums

It took me many days and hours to try and resolve the problems I was having with the apps.
I tried numerous “solutions” in various forums, all to no avail.
There was no way I was going to do a clean install, as I have far too many programs that would require re-installing.

I got various results using Powershell Commands and using WSReset.exe. - SFC /Scannow etc. None of them gave me a totally working solution. Access to “Store” and some other apps was never achieved.
After many failed attempts I finally resolved my issues.

Here is what I did:
I took ownership of C:\Program Files\WindowsApps and renamed it WindowsAppsold. The reason for renaming was in case I required to reverting it to its original name and it was too risky to just delete it.
I then ran WSReset.exe. (not sure if it was actually required, but it gave me the same error message that I’d seen numerous times, whilst trying various repair options. The error message was "You'll need a new app to open this MS-Microsoft Store".

I then disconnected my internet connection and disabled protection on my Norton Internet Security
Next I did an in place upgrade using a previously downloaded Win 10 ISO file for build 10586. This was run from within Windows and not from USB or disk.
I chose to keep all apps and files. Chose not to install updates and unchecked the other box.
After the in place re-install, I restored N.I.S. and my Internet connection.
The end result was: All the apps came back and I have a working Store too. J
The restore had created a new C:\Program Files\”WindowsApps” folder.
The renamed one still remains and I’ll delete it once I’m content that everything remains working okay.

I cannot guarantee this will work for everybody having the same issues, but it was the only one that worked for me.
After doing an update (Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB3120677)), the Store Icon developed an exclamation mark and I thought “here we go again”, but on clicking it, the store opened okay and the mark disappeared afterwards.

I've no idea why I started getting problems with the Apss. I can only think of a few possible causes. It was either the Windows Update or my use CCleaner to clean up registry files.

Good luck if you try this and I hope it works for everyone else having the same issues.

Great Minds... I did almost the same thing last night GravityFails, renamed the WindowsApp folder to Old_WindowsApps after taking ownership (we had to do this on a Windows 8.1 installation that had trouble so I thought I'd try it on Win 10). I did not disable my AV, nor disconnect from the internet. When I booted from my Windows 10 Pro ISO, the only option that was selectable was Clean Install.

Feeling very frustrated I then decided to try to roll back to Windows 7, clean it up, and then try the Windows 10 upgrade again after the next patch. "Windows cannot proceed because there is a file missing..." (paraphrased). I still have the 3 folders - Windows.old, BT and WS. It is just under 3 weeks since I finally upgraded. The Microsoft forums have several posts regarding this issue.

So, I checked I had copied my documents, exported my mail, and had all the drivers I had collected to work with Windows 10 ready on my spare drive and plugged in the RECOVERY USB. I was going to try a reset and see if that would finally fix my machine - so I selected Keep my files and settings, and off we went.

At 15% the program terminated with the message that there was an error in my Recovery Files and went to the Troubleshoot Bluescreen.
The only option that was selectable for me here was Power Off this Computer.
Upon reboot, lucky me, I get a "No Operating System Found" Error. I cry with sad for now I think I'll have to Reinstall Windows 7 Pro from my OEM disk, (and hopefully be able to activate it again) and then try the upgrade. I have the 1511 Upgrade disk sitting on my desk, and an Windows 10 Pro build 15 ISO dvd as well, but I'm not sure I can install from those and re-use my win 7 activation code. I'll be attempting to contact Microsoft today to see what my options are.

I'm an IT Professional and I have to slap myself silly for not following the advice I preach at work on my home environment.... I should have taken a backup after the Windows 10 Upgrade was finished - or at least created a restore point. I should have tried to see if there was a way to verify the Recovery USB was not corrupted (it did show FAT32 and has the demonstrated directory/file structure - so not sure how to test that).
I'm using Windows 10 Enterprise at work, so far I have upgraded 20 machines here to both Pro and Enterprise without a single hitch, and everyone here, myself included, are liking Win 10, it's ironic that it was my home machine (lucky 21) that decided to slap me upside with problems...
