Where to find CLEAN Windows 8 "default user" profile?

working on a Dell 15r that has the thumbnailextractionhost.exe bug so it is effectively impossible to do any repair functions that requitre a functioning windows 8. slaving the disk, I see the default user profile was migrated/recreated around the same time the users issues began, recently, and it has no other archived default-user profile that I can identify. I don't have media, of course, its windows 8.

can someone point me to an online source for a microsoft-issue default user profile.?

if anyone knows how to STOP the loading of thumbnailextractionhost.exe - a method that does not imply/depend-on a WORKING windows 8... amazing the things microsoft thinks up. their 'fixes' require the system to be working

i wold suggest creating a bootable anti-virus scan,

thanks for responding.
already done. it comes up clean with the common scans.
quite maddening: I search on the issue and there are lots of people with 8/8.1 that have this issue, but no sure cures. try this, try that. I have seen it go stable for brief moment, then starts all over again. it generates infinite retries of thumbnailextractionhost.exe until the system croaks [that's a lot on an i7 with 1TB drive!] nuts. I'm going to try one suggestion to turn off windows error reporting, but any of these 'fixes' are not really fixes, they are workarounds.
All of microsoft/technet posts I've seen begin with the premise THAT THE USER HAS A USABLE WINDOWS DESKTOP.
sorry for shouting, but its truly irrational.

i will agree to your shout. sorry but i would bail out and reload windows .quicker and cheaper.if somone is paying to have it fixed

speed was important, if possible, and you are right about the 'best way'. in a week or three I will refresh.
For now, the system is stable.

For those having this same issue [many in the wild], I do not know what the true root of this issue is, but the crippling symptoms stopped when Norton 360 was purged completely from the system. [Dell should be flogged publicly for putting that devil on Windows 8 systems]. System is performing well but there remains an issue with Thumnail creation and/or extraction. I could not immediately get the folder views to display thumbnails of images.

There is traffic in forums about the wicked behavior of recent iterations of NOrton 360 - it will corrupt and modify not only the extant user-created User accounts but the defaults. Very foul, very suspicious behavior and I did not see where anyone qualified at Symantec owned it.
