How to repair the Windows 10 Start menu apps

When it comes to using Windows 10, the Start menu app tiles are a popular way to open some of your favorite programs. But what happens if the app tiles stop functioning correctly? Here is how to repair the Start menu apps.

How to repair the Windows 10 Start menu apps

The Start menu apps are not standard desktop Windows programs; they are Universal Apps, UWP (Universal Windows Platform), to be exact. They are designed to run on all Microsoft devices, including Xbox, Surface Hub, and HoloLens. Microsoft has set quite a few of them as default apps in Windows 10 for opening photos, videos, music, etc.. So when they stop working, it can be a significant problem.

The steps outlined in this article should be taken in the order listed. Remember to restart your computer between each step so that changes have a chance to take effect. The links to the blogs referenced in each stage are highly detailed and will open in new browser tabs. That way, you don't have to worry about trying to get back to this article.

Reinstall the Start menu apps

This step is one of the most straightforward procedures and should fix the Start menu apps most of the time. All you have to do is copy a string of text and paste it into an Administrative PowerShell console.

There are several ways to open an Administrative PowerShell. Here are a few of the most popular

  1. Open an Administrative PowerShell using one of the following procedures.
    • Bring up the Start menu by left-clicking on the Start Windows logo button.
    • Scroll down to the Windows PowerShell folder and left-click on it.
    • Right-click on Windows PowerShell and select Run as Administrator on the context menu that appears.
    or
    • Bring up the Power User menu by right-clicking on the Start Windows logo button.
    • Left-click on the Windows PowerShell (Admin) link.
    or
    • In the search box to the right of the Start Windows logo button type PowerShell.
    • In the right-hand column of the search results, left-click on Run as Administrator directly below Windows PowerShell.
  2. You will get a prompt stating Do you want to allow this app to make changes to your device? Left-click on Yes.
  3. Copy and paste the following text into the PowerShell window.
    Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
  4. When the script is done running, close the PowerShell window by typing exit and press enter.
  5. Restart your computer.

Don't worry if a couple of errors are generated while running the PowerShell command. It happens even on a clean Windows 10 installation. If numerous errors are generated, then you may need to proceed with the following steps.

I once had a system that the Start menu apps would not reinstall because the Windows Security Service would not start. I had to repair it before I could get the Start menu apps working again. Remember that once you complete any of the following procedures, restart your computer and rerun the PowerShell command.

Check the drive for errors

There is a possibility that the Start menu apps are not functioning correctly because there are errors on your C:\ drive. Running a quick standard disk check may be just the thing your computer needs to get the Start menu apps running again.

And even if it doesn't fix the problem with the apps, it is always an excellent procedure to do before the next step. Here's how to run a standard drive check in Windows 10.

  1. Open File Explorer using one of the following:
    • Left-click on the File Explorer icon (manilla folder) on the Taskbar.
    • Press the Windows logo key Windows logo + E at the same time.
    • Use the Power User menu by right-clicking on the Start Windows logo button and selecting File Explorer.
  2. In the left-side column left-click on This PC.
  3. In the right-side column right-click on the drive you want to check and select Properties.
  4. Left-click on the Tools tab.
  5. Under Error checking left-click on Check.
  6. Left-click on Scan drive.

If you get an error when trying to run a standard drive check, you may have to perform an advanced check. Here are all of the details on how to do it.

Check system files for corrupt or missing files

Now some of the files the Start menu apps require to operate correctly may be missing or gotten corrupted. Windows 10 has a utility called System File Checker (SFC) that can detect and repair problems with files required by Windows 10 for properly operation.

Let me forewarn you that you may have to run SFC more than once to fix some of Windows 10 files. You may even have to start your computer in safe mode to get SFC to repair Windows 10. Here's how to run a basic SFC scan:

  1. Open an Administrator Command Prompt using one of the following.
    1. Left-click on the Start Windows logo button.
    2. Scroll down the program list and then left-click on the Windows System folder to expand.
    3. Right-click on Command Prompt.
    4. On the context menu that appears, hover your cursor over More and then left-click on Run as administrator. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
    or
    1. In the search box next to the Start Windows logo button, type Command Prompt.
    2. In the list of results, the Command Prompt should be highlighted.
    3. In the right-hand column under Command Prompt, there is an options menu. Left-click on Run as administrator. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
  2. Type sfc /scannow into the Admin Command Prompt and press enter.

And in the worst-case scenario, you may have to replace a corrupt file or two manually. Luckily there is a way to determine what files SFC repairs and what ones it cannot. The following article has all of the details on how to go about using SFC to its fullest potential.

Perform an in-place upgrade of Windows 10

The next step to getting the Start menu apps to working again involves doing an in-place upgrade of Windows 10. Even though it sounds kind of scary, it is relatively simple.

When performing an in-place upgrade, your documents, pictures, and videos stay perfectly safe. And you can keep all of the installed programs too. The only downside is the default programs for specific file types revert to Windows 10 defaults. To me, that is no biggie. The following article gives all of the details on how to do an in-place upgrade.

Reset Windows 10

This step is the completely last resort to fixing the Windows 10 Start menu apps. I defiantly don't recommend it, but I do have to suggest it (reluctantly) as an option. With resetting Windows 10, you can keep all of your documents, pictures, and videos. But all of the programs that did not come with Windows 10 will be gone. The following article gives all the details on how to reset Windows 10.

Check Windows 10 system files with System File Checker

Updated July 20, 2020

I was thinking the other day about what program I use the most in doing computer repair. The one program I use the most on Windows computers would have to be System File Checker (SFC). SFC checks for system files that may have gotten corrupt or replaced with incorrect versions. Here's how to check Windows 10 system files with System File Checker.

Check Windows 10 system files with System File Checker

SFC has been included in every version of Windows since Windows XP. You can also build it into the Microsoft Diagnostics and Recovery Toolset (DaRT). There is no shortcut or link to SFC in Windows 10, as it runs inside an Administrative Command Prompt.

How to open a Command Prompt with Administrator privileges in Windows 10

The following is the syntax and switches for SFC. The most commonly used syntax/switch is: sfc /scannow.

SFC [/SCANNOW] [/VERIFYONLY] [/SCANFILE=<file>] [/VERIFYFILE=<file>] [/OFFWINDIR=<offline windows directory> /OFFBOOTDIR=<offline boot directory>]

/SCANNOW (Scans integrity of all protected system files and repairs files with problems when possible.)
/VERIFYONLY (Scans integrity of all protected system files. No repair operation is performed.)
/SCANFILE (Scans integrity of the referenced file, repairs file if problems are identified. Specify full path <file>.)
/VERIFYFILE (Verifies the file's intergrity with full path <file>. No repair operation is performed.)
/OFFBOOTDIR (For offline repair specify the location of the offline boot directory.)
/OFFWINDIR (For offline repair specify the location of the offline windows directory.)

Examples

sfc /scannow sfc /verifyfile=c:\windows\filetobereplaced.dll sfc /scanfile=d:\windows\filetobereplaced.dll /offbootdir=d:\ /offwindir=d:\windows sfc /verifyonly

Once SFC is done scanning the system files, it will give one of four possible results:

  • Windows Resource Protection did not find any integrity violations.
    All system files are fine, and you're good to go.
  • Windows Resource Protection could not perform the requested operation.
    There may be another program preventing SFC from running. In this case, boot the system up into safe mode and run SFC from there.
  • Windows Resource Protection found corrupt files and successfully repaired them.
    All system files are now correct, and you're ready to go. If you want to view the repair details, see below.
  • Windows Resource Protection found corrupt files but was unable to fix some of them.
    If you get this message, SFC found a file or files that it couldn't repair. The next thing you will need to do is find out the name of the file(s). Using the Find String utility, you can filter out the SFC results with only the scanned components and create a text file with that information on your Desktop called sfcdetails.txt. Just copy the following code into an Administrative Command Prompt:
findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt"

Manually replacing a corrupt system file in Windows 10

Note: To replace a corrupt system file, you will need to have a known good copy of the file(s) in question. A good source for files is another computer or virtual machine running Windows 10. Since I do computer repair for a living, I have all of the versions of Windows that are still supported by Microsoft running inside of Oracle VirtualBoxes.

The first thing to do is note the location (path) and name of the file(s) that need to be replaced from the sfcdetails.txt file. Once you have another copy of the corrupt file(s), you will need to take administrative ownership of the file(s). To do this, modify the following command with the path\filename of the file you want to replace and then type it into an Administrative Command Prompt:

takeown /f path\filename

Example: takeown /f C:\Windows\FileToBeReplaced.dll

Next, you will have to grant administrators full access to the file(s) being replaced. To do this, modify the following command with the path\filename of the file you want to replace and then type it into an Administrative Command Prompt:

icacls path\filename /grant administrators:F

Example: icacls C:\Windows\FileToBeReplaced.dll /grant administrators:F

The third thing to do is copy over the new file(s) and replace the corrupt one(s).To do this, modify the following command with the path\filename of the file you want to replace and then type it into an Administrative Command Prompt:

copy path\filename path\filename

Example: copy C:\Temp\FileToBeReplaced.dll C:\Windows\FileToBeReplaced.dll

Check the protected system files in Windows with System File Checker

There may come a time when your Windows based computer starts to run improperly. Installing and uninstalling software, viruses and malware are just a few things that can corrupt the integrity of system files. When it comes to computer repair on a system running Windows, I always like to check for corrupt system files. You can too with Windows built-in System File Checker (SFC).

SFC scans the integrity of all protected system files and replaces incorrect versions with correct Microsoft versions. Everything SFC does is documented in the CBS.log file. So, if SFC finds any files that it cannot repair, check the CBS.log for more information. See the bottom of command line syntax(s) and parameter(s) for details on how to view the CBS.log.

Running SFC in Windows Vista, Windows 7 and Windows 8

To ensure that SFC runs with administrator privileges on Windows Vista, Windows 7 and Windows 8, you will need to run it at an administrative Command Prompt.

  1. Open a Command Prompt with Administrative privileges

  2. Use the following command line syntax(s) and parameter(s) to run SFC:

sfc [/scannow] [/verifyonly] [/scanfile=<file>] [/verifyfile=<file>] [/offwinddir=<offline windows directory>/offbootdir=<offline boot directory>]

/scannow Scans integrity of all protected system files and repairs files with problems when possible.
/verifyonly Scans integrity of all protected system files. No repair operation is performed.
/scanfile Scans integrity of the referenced file, repairs file if problems are identified. Specify full path <file>.
/verifyfile Verifies the integrity of the file with full path <file>. No repair operation is performed.
/offbootdir For offline repair specify the location of the offline boot directory.
/offwinddir For offline repair specify the location of the offline windows directory.
/? Displays help at the command prompt.

You can view the CBS.log file in Notepad by using the following code at the same administrative Command Prompt used to start SFC.
notepad %systemroot%\Logs\CBS\CBS.log

Running SFC in Windows XP

To use SFC, you will need to open a Command Prompt.

  1. Click the Start button, then Programs, then Accessories, then click on Command Prompt
    or
    Press Windows logo key + R. This will bring up the Run dialog box. Type CMD and click OK
  2. Use the following command line syntax(s) and parameter(s) to run SFC:

sfc [/scannow] [/scanonce] [/scanboot] [/revert] [/purgecache] [/cachesize=<x>]

/scannow Scans all protected system files once.
/scanonce Scans all protected system files once.
/scanboot Scans all protected system files every time the computer is restarted.
/revert Returns the scan to its default operation.
/purgecache Purges the Windows File Protection file cache and scans all protected system files immediately.
/cachesize=<x> Sets the size, in MB, of the Windows File Protection file cache.
/? Displays help at the command prompt.

When SFC is done, you can view the log file in Notepad by using the following code at the same Command Prompt used to start SFC.
notepad %systemroot%\Logs\CBS\CBS.log
