Gfxui.exe Has Stopped Working Error? Repair Tip!

Drivers diagnostics tool

Details about Gfxui.exe
For those who are concerned – it is a legitimate file from Intel Corporation.
This file is part of a component called: Intel Graphics Properties and it controls the graphic user interface of Intel’s onboard video. You can find it in various laptops such as HP Pavillion, Dell, and Lenovo Thinkpads.

It is usually located in the following path: C:\Windows\System32

Common problems
This file is usually ‘involved’ with several problems, most of them occur right after computer starts ups: BSODS (Blue Screens of Death), slow downs, errors messages like: GfxUI has stopped working or something about the file is not a valid win32 application or unable to start the file.

Two reasons why these errors occur
As I mentioned earlier, there’s one common reason – a driver problem, and a less common reason – security permissions settings.

Step-by-step repair guide:

(1) Detect and replace problematic drivers
I’ll begin with the most common reason – defective driver(s).
Since Gfxui.exe is part of one of your drivers it probably either got corrupted or replaced by an incorrect or incompatible driver (might occur during a recent Windows update as one example).

It might also happen to be that other defective drivers are involved in this problem as well. The easiest way to know which driver(s) is causing all that trouble is using the following drivers diagnostics tool. In about 1-2 minutes it’ll detect any existing problematic driver and enable you to immediately replace it with correct and compatible one.

To make a long story short…

(1) Download the following drivers diagnostics tool
(2) It’ll conduct a comprehensive drivers scan
(3) When it finishes scanning, open the Drivers section
(4) Replace all problematic drivers
(5) Restart your PC

This should solve the problem.
If from some reason it didn’t solve the problem, then this might be due to incorrect security permission settings of this file.

(2) Change Gfxui.exe security permissions settings
(1) Login to Windows using your default Admin account
(2) Access the following folder: \Windows\Microsoft.NET\Framework\v2.0.50727
(3) Right Click on \Config\ folder -> Select Properties
(4) Click Security tab and click Advanced
(5) Click the Owner tab, then click Edit…
(6) Change ownership from Trusted Installer to default Administrators group
(7) Go back to Security tab -> click Edit…
(8) Change the Administrators group permissions to Read & execute
(9) Restart Windows, login again using the default admin account - see if problem is gone

If the Gfxui.exe error has stopped, then you can login to Windows again using any user account.
