Processor Diagnostic Tool MMXSSE Fail "could not load DetectUtils64.dll" Intel Core I5 8600k

[Ave_]

Hi, Im gonna try to keep it short while explaining everything as detailed as I can:

I suddenly had problems playing games: they were very laggy and the cpu ussage in the taskmanager was extremely high (even at 100%). Which is pretty unusual since even csgo had these problems even tho I have an  I5 8600k.

I googled and searched the web because I figured other people might have the same problem and tried some weird reg edits and stuff but nothing changed anything, then I came across the Intel Processor Diagnostic Tool and the Test failed:

I ran the system support unit and attached my results.

I hope you can help me.

Please do not try or resort to "weird reg edits and stuff".

What anti-virus software do you have installed? What firewall?

Are you using any cleaners?

Why are you using windows 10 version 1709 (from more than two years ago)? Update to version 1909.

Thanks for the response!

1. I thought that maybe it was a well known thing and that there could be an easy solution idk
2. I deactivated both cause I was already suspecting them to be the problem
3. I run ccleaner like every two months
4. Thats something I never noticed thank you! I just tried to manually update it and got Errorcode "0xc1900204" which is probably also the reason why my windows didnt automatically update. Im gonna look into how to get the newest version without losing my programms and stuff tomorrow thx

Update your windows from here:

Also, stop using cleaners. They can cause more harm than good, and never use the registry cleaner.

Another user just had a similar problem with IPDT, and discovered it was his use of avg and cleaners. I suspect your problem is the same, which means you need to do a clean install of windows, or reset windows, and get rid of those third party virus checkers and tools. Avast/avg/ccleaner are not helping you.

I had the same issue with the "could not load DetectUtils64.dll" error. Here's what worked for me:

Make sure you are running the Diagnostic Tool from your C: drive (or boot drive, maybe?). I originally installed mine on a secondary disk (D:) and it kept failing half the tests because of the missing .dll. Uninstalled and reinstalled on my boot drive (C:) and no problems!
