I started today with a nag prompt for "EFS UI " to back up my file encryption key. This was confusing as I don't use file encryption. Anyway I ran "cipher /u /h >files.txt" an an admin comand prompt and find a load of ...AppData\Local\Intel\oneapi\Samples\Archive\oneapi-samples-9016e02b5a2d890c171a444d6afb6fd3340320f9\DirectProgramming\C++\CombinationalLogic\MandelbrotOMP\cpp.tar.gz type archives that are encrypted and in the registry there is an encryption key that had been created under my username.
This seems most odd, is this intended behaviour?
I'm experiencing the same with the C++ compiler. Would you happen to remember where the encryption key was in the registry? I'm struggling to find it in certmgr.msc and I keep getting the reminder to back up the key occasionally.
Personally I find it rather strange that someone felt the need to make the installer encrypt these files...
Sorry I don't have any recall of this or how I killed the nag prompt. I would imaging under cipher.exe application see https://support.microsoft.com/en-us/topic/cipher-exe-security-tool-for-the-encrypting-file-system-56c85edd-85cf-ac07-f2f7-ca2d35dab7e4
