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.

Option 1 – Try updating the application or software

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:

• Look for the built-in option to check the updates since the most application has this option.
• You also have the option to go to the website of the application and check if there is a new version available. If there is, download and update the app.

On the other hand, if you have downloaded the app from the Microsoft Store, here’s what you have to do:

• Open the Store and click on the three dots located at the top-right of the window.
• Next, click the Download and Updates option.
• From there, check if there is an update available for the store. If there is, update it.

Option 2 – Try to uninstall the application or software

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.

• In the search box, type in “control” and then click on Control Panel (desktop app) among the search results.
• After that, select Programs and Features from the list which will give you a list of all the programs installed on your computer.
• From there, look for the concerned program and select it and then uninstall it.

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.

Option 3 – Try bypassing the Upgrade Advisor

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.

There is a built-in tool in Windows 10 the Disk Cleanup Utility which can help you restore hard disk space by removing temporary files, Thumbnails, old Windows files, Windows Upgrade logs, Delivery optimization files, and many more. However, from time to time, this built-in tool also experiences some issues. One of these issues is when it gets stuck on Windows Update Cleanup. Read on to find out what you can do in such a case. When the Disk Cleanup Utility is stuck on the Windows Update Cleanup, the process could be slow and take a long time to complete when purging the files. If this happens, click on Cancel to close the dialog box. After that, try running the Disk Cleanup Tool again as administrator and check if the files that you want to clean is still there or not. If it isn’t there, then this means that the cleanup has been done, otherwise, you need to refer to the options given below.

Option 1 – Try to manually delete the contents in the SoftwareDistribution folder

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer and then try to run Windows Update once more.

Option 2 – Try to manually delete the contents of the Windows.old folder

The Windows.old folder is the one that holds the older version of Windows when you upgrade. It comes really useful when you want to revert to the previous version of Windows 10. Thus, you can delete the Windows.old files in case the cleanup tool is stuck.

Option 3 – Try running Disk Cleanup in a Clean Boot State or Safe Mode

Another thing you can try is to restart your computer in a Clean Boot State or Safe Mode. Chances are, there are some programs that are preventing the Disk Cleanup Utility tool to run properly. After you restart your computer in a Clean Boot State or Safe Mode, try to run the Disk Cleanup tool again and then see if it now works or not.
