Run the Windows Update Troubleshooter

Since the issue is most likely related to a known WU inconsistency that Microsoft is already aware of, you should start this troubleshooting guide by checking if your operating system is not capable of identifying and fixing the 0x8007371C error automatically. Note: Windows 10 includes a lot of built-in repair strategies capable of resolving the vast majority of update-related errors and inconsistencies. Some users that we’re facing this exact issue have managed to fix the 0x8007371C by running the Windows Update troubleshooter and enforcing the recommended fix. This built-in utility is present on every recent Windows version and contains dozens of repair strategies that will be applied automatically if a familiar scenario is found. In case the scan finds a viable repair strategy, the utility will automatically recommend a viable fix that you can easily apply. Here’s a quick guide on deploying the Windows Update troubleshooter to resolve the 0x8007371C error code on Windows 10: If the 0x8007371C is still occurring when you attempt to install the pending update (or the troubleshooter didn’t find a viable repair strategy), move down to the next potential fix below.

Reset every WU Dependency

If the Windows Update Troubleshooter was not able to identify and fix the issue automatically, you should advance this troubleshooting attempt by manually resetting the entire Windows Update component. To work around this problem, you use an elevated Command Prompt to stop every relevant Windows Update settings before cleaning up any temporary files stored within SoftwareDistribution and Catroot2 folders – After doing this and restarting every relevant service, you should attempt to install the pending updates once again and see if the issue is now fixed. If you haven’t tried this particular fix yet, follow the instructions below to reset every Windows Update Dependency in an attempt to fix the 0x8007371C: If your attempts at installing pending updates still end with the same 0x8007371C error, move down to the next potential fix below.

Install the failing Windows Update manually (via Microsoft Update Catalog)

In Windows Update troubleshooter didn’t allow your to identify any underlying issues with the Windows Update component, one quick fix that that should allow you to bypass the 0x8007371C error is to use the Windows Update Catalog to find the update that is failing to install and install them manually (most commonly when attempting to update to Windows 10 build 1903). This operation was confirmed to work by a lot of affected users – This process might be a little tedious (especially if you’re dealing with multiple updates that are all failing with the same error), but it’s worth it if you want to completely bypass the reliance on the built-in Windows Update component. Note: If you have a lot of pending updates (over 10), it might be better to bypass this method and move directly to Method 3. If you decide to go through with this fix, follow the step by step instructions below: In case you’re still seeing the same error code when you try to install the updates via the Windows Update catalog, move down to the next potential fix below.

Use System Restore

If you only noticed that pending Windows Updates have started to fail after a certain change (driver update, new driver installation, new feature update, etc.), you might be dealing with a rogue element that conflicts with the Windows Update component. In this case, you might be able to fix the problem by using System Restore to restore your computer back to a healthy state. Note: Keep in mind that by default System Restore is configured to create and save new restore snapshots at important system events. Unless you modified this default behavior, you should have plenty of restore snapshots to choose from in your attempt to fix the ‘SiHost.exe Unkown Hard Error‘. Use a previously saved System Restore point to revert your computer back to a previous point in time when this issue was not occurring. If you managed to use a restored snapshot to revert your PC back to a healthy point, attempt to install the Windows Update that was previously failing once again. If the problem is still not fixed and you’re still seeing the same 0x8007371C after an update fails, move down to the next potential fix below.

Repair Installing or Clean Installing

If none of the potential fixes above have worked for you so far, there’s a very high possibility you’re dealing with some kind of system file corruption that is affecting the local Windows Update component. If this scenario is applicable, the only thing you can do at this point is to reset every component and subcomponents of your Windows installation to ensure that you completely eliminate every corrupted instance that might be triggering the 0x8007371C error code. If you have no choice but to do it at this point, you really only have 2 ways forward:

Clean install – If you’re looking for a quick fix, go for a clean install since you can deploy it without having to use compatible installation media. This will effectively replace your existing lineup of Windows files from the OS drive and eliminate any corrupted instances. But keep in mind that unless you back up your personal data in advance, you need to be prepared to lose every bit of personal data from your OS drive (C:).Repair install – This procedure will take a lot longer and it will require you to insert a compatible installation media and use it to trigger an in-place repair procedure. But repair installing will allow your to keep your personal files including applications, games, documents, photos, etc.
