What is Windows Update Error 0xC1900209? Before you can install any updates on your Windows 10 computer, there are a lot of conditions that have to be fulfilled and one of these conditions is software compatibility. It is one of the important factors in installing Windows Updates. So if one of the software in your computer is not compatible with the new Windows Update for your OS, then the Windows 10 setup will not proceed and will block the installation of the new update. This both applies to the cumulative updates and feature updates. In such cases, you will get the following error message when you run Windows Update:
“0xC1900209, Incompatible software is blocking the upgrade process. Uninstall the application and try the upgrade again.”
This error message comes under the umbrella of the Windows 10 pre-upgrade validation using Setup.exe. And for you to identify the incompatible app, you need to grab a Windows 10 install image using the Windows Media Creation tool to download the suitable Windows 10 version and mount it. After that, execute the setup.exe file that’s located in the root folder of the Windows 10 install image. Once you execute the setup file, the upgrade wizard will give you a list of incompatible apps.
Once you have determined which software is not compatible with the Windows Update, there are two options you can try to resolve the Windows Update error 0xC1900209 – you can either try to update the conflicting software or uninstall it. For more details, follow the given options below.
If you are using an older version of the software that’s in conflict with the Windows Update, you might want to update it to its latest version and then try to apply the updates again to your Windows 10 computer. You can update the concerned software by visiting the official website of the software or any of its distribution sources. On the other hand, you can also use the Check for updates feature of that particular software if it’s available.
If updating the problematic program didn’t work, the next option you can try is to uninstall it. All you have to do is follow these steps to uninstall it successfully:

Error Causes
Error CausesOne common issue when trying to upgrade to Windows 10 from Windows 7 or 8 is incompatible software. Any installed software or app that isn’t compatible with Windows 10 will prevent you from continuing with the set-up. Normally, you’ll get an error message “What needs your attention” and it will ask you to uninstall a list of apps manually. Unfortunately, some users reported that they couldn’t find the app it asks to uninstall. In some cases, users said they’ve already uninstalled the app but it still won’t start the Windows 10 Setup.

Instead of using the “add or remove programs” feature in Windows, you might need to manually install the program directly from the C drive. To do this, follow the steps below:
Note: In some cases, you may also need to search for files related to the program. You can use the search bar under Drive C to do this. Delete those files as well.
Before upgrading to Windows 10, create a new user account. Make sure it has administrative privileges. From there, run the upgrade.
If you still can’t run Windows 10 Setup after the above methods, you might need to rely on a third-party service. Microsoft recommends Revouninstaller that can help you.
Before using this software, reinstall the application or utility that Windows 10 wants you to install. Then, use Revouninstaller to delete the program completely.
Some users who experienced this issue reported that it was solved after disabling or completely uninstalling the anti-virus software installed in their system.

The greatest lag and server crashes are pinpointed to game-creating events. When a player creates a new online game, the server needs to pull a lot of details from the database and make a game, due to some legacy code present this process takes some time and it is demanding a bit on the server-side, and although code was optimized to cater to more modern approach some legacy code still remains.
Another thing that was spotted to affect performance itself is player behavior, to be more specific, modern gamer behavior. Where players find good builds and runs on the internet and then go to farm-specific areas or bosses for loot or experience points, which in return boils down to making plenty and short runs that are made by creating games and after run eliminating them. Now pair that with the previous statement about legacy server and database code and you can add 1 and 1 and see how this might be an issue.
A lot of short games over legacy code are placing games in a state it was not designed for back in 2001 and therefore we have issues. Sadly solutions without completely rewriting the whole code are not very promising and they include rate limiting, which will prevent players to create many games in succession in a short period of time and maybe even login queues to drop a load on servers.
Blizzard reached to people in the whole company, even old diablo 2 developers to ask for advice and they say that they are working on solutions so they could lift limitations and have everything running fine.
