Updating to Windows 10 isn’t always smooth as it expected. Users have reported that file GWXUX.exe gives them an annoying ‘Application Error‘ alert while trying to update to Windows 10.
What is gwxux.exe?
First off, let’s explain what GWXUX.exe does. This application is in charge of updating your Windows 7, Windows 8 or Windows 8.1 to Windows 10.
If you’re using older version of Windows, you’ve probably noticed the little icon in your Taskbar that asks you to update to Windows 10.
That is GWXUX.exe, it scans your computer in order to see if your system is compatible with Windows 10, and it informs you when the update is ready to be downloaded.
However, after clicking the icon and trying to update to Windows 10 many users have received an Application Error. If you’re having this problem, don’t worry, there is a way that you can fix this.
How can I fix gwxux.exe application errors?
However, for some users this isn’t the best solution, especially if you don’t want to deal with backing up of your files and reinstalling your software all over again. But don’t worry, you can repair corrupted system files without installing a fresh copy of Windows.
Solution 1 – Perform a SFC scan
SFC stands for System File Checker, and it will scan your system for corrupted files and it will repair them. To perform SFC scan, you need to do the following:
- If you’re on Windows 8 or Windows 8.1, go to the bottom right of your screen and open Search. Then type Command Prompt in the search box and find the Command Prompt application from the list. Right click it, and select “Run as administrator”. You might have to enter your administrator password to proceed or allow the application to run.
- On Windows 7 it’s almost the same. Open the Start menu, in the search box type Command Prompt, right click the application and select “Run as administrator” from the context menu. Again, you might need to enter your administrator password or to allow the Command Prompt to run.
- Next step is the same for both Windows 8 and 7. Command Prompt will open up and you’ll need to type sfc /scannow in it. Just press Enter and SFC scan will perform, replacing any corrupted files it finds.
- Before starting SFC scan please close all other applications, and do close Command Prompt until verification is 100% complete.
- After the scan is complete, you’ll be notified if SFC has managed to find and repair the corrupt files. If the corrupted files have been repaired the GWXUX.exe Application Error should be fixed.
Solution 2 – Run DISM
- Open Command Prompt as an administrator
- Enter the following commands one by one and hit Enter:
- Reboot your computer and check if the error persists.
Solution 3 – Reinstall your Windows
If the issue cannot be fixed with SFC scan, and you’re still getting GWXUX.exe Application Error you might need to reinstall your current version of Windows. If you don’t know how to do it, hire someone to do it for you.
