As you know, the Windows Update process takes compatibility seriously. The Windows Updates need to be compatible with the hardware as well as all the installed applications in the computer else the Windows Updates will only get stuck in the process. Two of the Windows 10 errors that shows up during this case is the error 0xC1900208, 0x4000C.
These error codes are caused by incompatible applications which means that there might be an incompatible app installed in your computer that’s blocking the upgrade process and prevents it from finishing. That’s why you need to make sure that all the applications on your computer are updated to their latest versions and then check the compatibility. So if there are any incompatible apps, be sure to uninstall them and then try doing the upgrade once again. Take note that these error codes are just among many compatibility issues that the Windows Update throws up.
Since the error is caused by a compatibility issue, you have three options – first, you can update the incompatible application to the latest version, second, uninstall the application or trick Windows and make it seem like it’s compatible.
As mentioned, you can try updating the concerned application or software to its latest version to resolve the compatibility issue and in turn, fix the errors 0xC1900208 – 0x4000C. Note that depending on where you had installed the application, your steps will change. So if you have it installed directly from the website, refer to these steps:
On the other hand, if you have downloaded the app from the Microsoft Store, here’s what you have to do:
If updating the app or software to its latest version didn’t help and you’re still getting the error 0xC1900208 – 0x4000C every time you attempt to install the Windows Updates, you may have to uninstall it. You will need to use the usual Program and Features to uninstall it if you have downloaded it from the website.
Note: If you have downloaded the app from the Windows Store, you can simply right-click on it from the application list and then uninstall it.
There are times when a software developer fails to pass the compatibility test for their apps. It could be that they work on Windows 10 upgraded version but just didn’t pass the compatibility check. So if you are pretty certain that the app really works on Windows 10, you can just bypass the Upgrade Advisor.
