If your Windows 10 computer is downloading or installing updates but suddenly an error pops up saying, “GWXUX has stopped working”, read on as this post will show you what you can do to resolve the problem. GWXUX is a process responsible for downloading and installing Windows updates and is installed on your computer via Windows Updates. That particular update is known as “KB3035583”. Through this process, the “Get Windows 10” pop-ups are installed and initiated by Microsoft. This process is also capable of checking the compatibility of your PC to run Windows 10 as well as preparing it for installation. However, this process might also result in excessive usage of Disk and sometimes, CPU. So in this post, you will be guided on how you can fix the issue with the GWXUX. Follow the instructions given below carefully.
You will have to disable the gwxux.exe process to run from the Task Scheduler. Thus, you need to follow the steps below to do so.
System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files that might be causing the error 0x80200056. To run the SFC command, follow the steps given below.
The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:
After running the System File Checker, restart your computer and check if the error with the GWXUX.exe file is now fixed or not.
“Your PC ran into a problem and needs to restart. We’re just collecting some error info, and then we’ll restart for you. (0% complete) If you’d like to know more, you can search online later for this error: 0xc000021a”This error pops up when a user-mode subsystem like the WinLogon or the Client Server Run-Time Subsystem or CSRSS has been compromised fatally and security can no longer be guaranteed in the system. Thus, the operating system switches to kernel mode, and Windows won’t be able to run without the WinLogon or the Client Server Run-Time Subsystem. This is why it’s one of the few cases where the failure of a user-mode service can shut down the system. To resolve the issue, here are some fixes that might help.
One 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.
This type of issue normally occurs because of the following:
Here are some steps you can take whenever you encounter this error.
Note: Before taking any steps, make sure that you’re highly equipped to do so. Some steps might affect the system and even do more damage to your computer. You might also want to consider using an automated tool instead.
A clean boot is normally done to start Windows using the least set of drivers and startup programs available. By doing this, it eliminates possible software issues that happen when installing or uninstalling a program in Windows 10.
Before performing a clean boot, make sure to take note of the following:
Here are the steps to perform a clean boot.
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.
If after trying the above methods, the problem still persists, it might be best to use a trusted automated tool to fix the issue.
“Updates failed There were problems installing some updates, but we’ll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: 2018-07 Cumulative Update for Windows 10 Version 1803 for x64-based Systems (KB4345421) – Error 0xca00a000”This kind of Windows Update error pops up when Windows has missed installing one of the cumulative updates needed or when there is some problem with the driver that won’t let the installation of the updates push through. There are also instances when the system files are modified with incorrect permission that may result in the Windows update error 0xca00a000. Thus, you need to fix the trusted installer permission as well as resolve the issue with the driver. To do these things, you need to follow the options laid out below.
