Error Code 0x803FB107 on Windows Store

What is causing the Windows Store Error Code 0x803FB107?

We investigated this particular issue by looking at various user reports and trying out different repair strategies that most affected users have successfully used to resolve the issue. As it turns out, there are a couple of different scenarios with the potential of triggering this particular error code. Here’s a shortlist with potential culprits that might be responsible for the issue:

  • Microsoft Server issue – The error code may be occurring due to a Microsoft server issue. In this particular case, the only viable troubleshoot guide is to confirm that the issue is beyond your control and wait for the issue to be fixed by Microsoft’s engineers.
  • Bad Windows update – Another possible cause for this particular error code is a glitched introduced with the 1803 update. Fortunately, since then, Microsoft has released a hotfix for this issue that should fix the issue entirely. To take advantage of it, all you need to do is install every pending update on your Windows 10 computer.
  •  Windows Store glitch – It turns out that this problem can also be caused by a temporary glitch that is reported to occur with the Microsoft store. If this scenario is applicable, you should be able to resolve the problem by signing out and into your Microsoft account connected to the store.
  • Corrupted Windows Store cache – The Windows Store cache can also be responsible for this particular error message. The issue can be facilitated by a security scanner or a botched update. In this case, taking the steps appropriate to reset the Windows Store cache should resolve the issue promptly.
  • Corrupted Windows Store files – It’s also possible that the problem is being triggered by one or more corrupted files belonging to the Windows Store that cannot be reset conventionally. In this case, you should be able to resolve the issue by resetting the app from an elevated Powershell window.
  • System file corruption – A less common but confirmed culprit is corruption inside the Windows folder. Since Windows Store works with a lot of dependencies, the problem will persist until you deal with the corrupted files. If this scenario is applicable, you can fix the issue by performing a repair install.

If you’re currently struggling to resolve the same error message, this article will provide you with several different troubleshooting guides. In the next section, you’ll find a collection of methods that other users in a similar situation have successfully followed to resolve the 0x803FB107 error code. Each of the potential fixes below is confirmed to be working by at least one affected user.

For the best results, we advise you to follow the methods below in the same order that we arranged them in (we ordered them by efficiency and difficulty). If you stick to the plan, you should eventually stumble upon a fix that will resolve the issue regardless of the culprit that’s causing the issue.

Before beginning with the solutions, make sure that you are using a wired network. Also, your system has enough space available on the system drive. Moreover, check your Internet for any interruptions. Most importantly, make sure your system meets the minimum requirements to run the game/application from the Windows Store. Also, make sure your system’s date, time and timezone are correct. If you are using any proxy/VPN then disable them and check if the Windows Store is operating fine.

Let’s begin!

Method 1: Exclude a Server Issue

Before we explore other repair strategies, let’s make sure that the issue is not beyond your control. There’s a real possibility that the problem occurs due to a server issue. It could be scheduled maintenance in your region or simply an unexpected outage problem.

Method 5: Reset the Windows Store Cache

Another potential problem causer that will trigger the Windows Store error 0x803FB107 is some degree of corrupted system files. In most cases, this is applicable in situations where a security scanner has recently quarantined some items.

Several users that were also encountering this issue have reported that they managed to resolve the 0x803FB107 error code by resetting Windows Store an all components associated with it.

Fortunately, there are two different ways of doing so on Windows 10. The first option is quicker, but it involves doing things from a CMD terminal. The second option involves more steps but it’s certainly more appealing to those without many technical abilities (it’s all down from Windows’s GUI).

Feel free to follow whichever method is more convenable to your particular scenario:

Resetting Windows Store via CMD window

  1. Open a Run dialog box by pressing Windows key + R. Next, type ‘cmd’ inside the text box and press Ctrl + Shift + Enter to open up an elevated Command Prompt. If you see the UAC (User Account Control) window, click Yes to grant administrative privileges.
    Running Command Prompt as an administrator

Resetting the Microsoft Store

If the same Windows Store error code (0x803FB107) is still occurring, move down to the next method below.

Method 6: Reset Windows Store Via An Elevated PowerShell Command

If resetting the cache didn’t resolve the issue, you can probably assume that there’s something wrong with your Windows Store application. In cases like this, you should resort to a more severe approach…

One method that was confirmed to work by a lot of affected users is to use an elevated Powershell window to do a hard reset on the Windows Store application – as if you were to start it for the first time.

This procedure should end up resolving most cases where the issue is caused by file corruption. Here’s a quick guide on resetting the Windows Store via an Elevated PowerShell window:

  1. Press Windows key + R to open up a Run dialog box. Next, type “PowerShell” and press Ctrl + Shift + Enter to open up an elevated Powershell prompt. When you see the UAC (User Account Control) window, click Yes to grant admin access.
    Typing in “Powershell” and pressing “Shift” + “Alt” + “Enter”
  2. Once you’re inside an elevated Powershell window, type the following command and press Enter to reset the Windows Store:
    Get-AppXPackage -AllUsers -Name Microsoft.WindowsStore | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml" -Verbose}
  3. After the command is processed successfully, restart your computer and see if the issue is still occurring at the next system startup.

If you’re still encountering the 0x803FB107 error code, move down to the next method below.

Method 7: Temporarily Disable Anti-Virus/Firewall

In the law-less universe of the world wide web, your Anti-virus/Firewalls are one of the most important security applications to safeguard your system from online threats. But sometimes these applications start to block the legitimate operation of genuine software applications and that can also cause the current Windows Store error. In that case, temporarily disabling Anti-virus/Firewalls may solve the problem.

Warning: Proceed at your own risk as disabling your antivirus/Firewalls makes your system vulnerable to threats like viruses, malware, infections, and malware, etc.

  1. Disable Antivirus.
    Disable Antivirus
  2. Disable Firewall.
    Turn Windows Defender Firewall off in the type of network
  3. Now access Windows Store and check if it is operating fine. If you have some other third-party Antivirus software, you have to disable that as well.

Method 8: Create a New User Profile

If your user profile has corrupted, then it can cause the 0x803FB107 error of the Windows Store. In that case, creating a new user profile/account and accessing the Windows Store through that account may solve the problem. Every user account in Windows has its own personal preferences and configurations. These might interfere sometimes with Store mechanics and hence cause the error message.

  1. Create a new user profile/account.
  2. Now access Windows Store and check if it is functioning without any issue. If it is, you can consider moving your files from the old account to the new one.

Method 9: Perform a Windows Reset

If none of the potential fixes above has allowed you to resolve the issue, chances are you’re dealing with a severe corruption instance that can only be resolved by resetting every Windows components. The easiest way to do this is by performing a clean install (here), but this procedure will also make you lose any personal files, applications, and user preferences.

A more efficient way to go about resolving corrupted instances would be to perform an in-place repair (repair install). This route will still reset all Windows Components + boot data, but it will allow you to keep all your files (applications, games, videos, images, applications, etc.)

Choosing the reset option

If you want to go ahead and perform a repair install, follow the instructions (here) for step by step instructions on how to do this.
