Windows 10: application has been blocked from accessing graphics hardware

Having the same problem too, since a few days and haven't found any solutions, including the ones posted in several of these threads in here. It's very very annoying and the more that there's still no solution after so long. 

I'm running Windows 10 in Bootcamp on a late 2013 iMac with native drivers, all up to date, all applications worked fine for months and now the problem occured. Tried everything suggested, but nothing works. None of the methods suggested by Microsoft representatives work. Microsoft obviously doesn't either. I'm this close to wiping Windows 10 off of my system again and forget about it. If I only use MacOS at least I KNOW why stuff doesn't work. 

In Windows 10, no one knows why it occurs, no one knows how to dodge it and MS reps are guessing as much as anyone else. This is so frustrating to get the message and sort it out yourself. >.<

Got "MicrosoftEdgeC was blocked from accessing graphics hardware".  My graphics is "Intel HD graphics 530" only.  Running Windows 10, i7 6700 cpu.  I have the most recent Intel driver for my graphics device (i.e. 21.20.16.4590).  Had been having screen tearing for several months, now this has occurred.  Before this happened the display was solid. 

Odd, the screen tearing occurs in the section of the screen where the "Start" tiles are, or in a browser, or in games (like MS solitare, MS minsweeper or MS Mahjong).  Plus sometimes get artifacts (i.e. green pixels flashing on/off) in other sections of these screen sections.  NOTE: my desktop is rock solid, as well as MS Office 2010 and any other desktop applications.

Hi,

We would like to know if you've tried the troubleshooting steps posted by Mohan Babu ER above.

We'll be waiting for your response so we can further assist you.

Hello Tom

I to had this issue.

Lucky me, my graphics card needed replacing and was still under warranty. Was an AMD Radeon R9 200 Series. Now have Nvidia works perfect.

Everything worked on windows 7 pro 64bit and once I upgraded to windows 10 it went faulty.

It could be a faulty driver on windows that pops the card but Microsoft won't say anything even it were true.

My suggestion will be to get a new card because there is a fault on the current card.

I tried the steps from Mohan Babu ER, but had to do some variations.  However, my issue still persists.

Steps I did:

For us to better isolate what's causing the problem, we suggest that you perform a clean boot by following the steps on this article.

Note: Please go through the section: How to reset the computer to start as usual after troubleshooting with clean boot of the Kb article to boot the computer in normal startup after fixing the issue.

Let us know the outcome of this method.

Hey Uncle Bern, did u ever get to the bottom of this. It has just started cropping up on my system too. It pretty annoying.

Thanks

I had updated to Intel's latest driver for my Intel HD graphics 530 device (Intel 15.45.16.4627 [which in the graphics 530 properties shows as 21.20.16.4627]) and still had problems.  Then the next weekly Microsoft Windows 10 update came out and everything was working perfectly. 

Everything was stable for about two weeks, then the artifacts started to return.  Not as bad as the prior ones but still some screen tearing and flickering graphics and some sprites.

It seems to be in those area that are heavily graphically oriented (Start tiles, Browsers [Edge, Firefox, Chrome] and the Google Earth globe & street view).  My desktop and MS office and other desktop programs are stable.
