How to fix
MicrosoftEdgeCP.exe error
on Windows

Hello. I use Microsoft Edge as my default web browser, and I never had problems with it. However, recently, there has been an annoying error message (Application Error: MicrosoftEdgeCP.exe stopped working) popping up every single time I start Edge. I tried to reinstall the browser, but it does not seem to have any effect. Could you please help me to resolve this issue?

MicrosoftEdgeCP.exe is a part of Windows OS and is associated with Microsoft Edge web browser. However, most of MS Edge related errors occur on Windows 10 OS. These errors might be caused by different reasons, including faulty OS install, flawed web browser installation, corrupted registry entries[ref en-1] or even malware[ref en-2] infection.

Microsoft, knowing that Internet Explorer has a fairly bad reputation,[ref en-3] developed Microsoft Edge and included it into Windows 10 release, promising a fast and reliable browser. Indeed, it seemed like the computing giant managed to convince users that the browser is worth keeping.

However, users started to experience some problems with Microsoft Edge. It seemingly happened since the update W10 ver 1703 build 15063.608 which came from KB4038788. Multiple users reported receiving various errors relating to MicrosoftEdgeCP.exe file, including:

• "Cannot find MicrosoftEdgeCP.exe."
• "MicrosoftEdgeCP.exe is not a valid Win32 application."
• "MicrosoftEdgeCP.exe Application Error."
• "MicrosoftEdgeCP.exe failed.”
• etc.

Typically, these errors arise as soon as MS Edge is started or on the boot up of the Windows 10. It has been reported that after closing down the error message, the browser works fine. However, dealing with annoying glitches popping out of nowhere is not acceptable, and should not be a part of any browser.

As MicrosoftEdgeCP.exe is legitimate Windows file, it rarely poses a risk of malware infection. However, trojan horses[ref en-4] allow files to disguise as useful files or replace original ones and start causing error messages. Therefore, before you proceed with the fix, you should make sure that the culprit is not malware. Download and install [rev id=“Reimage"] and perform a full system scan.
