Just a thought - have you taken a good look through the system event log (Event Viewer -> Windows Logs ->System) to see if there are any clues there ?
Good idea, Gammy.
But how on earth can the problem only show with regedit?
Well that's the thing - I would suspect that you just happen to be seeing the symptoms first with regedit, but whatever's wrong will eventually cause more widespread problems.
Case in point: I recently helped a relative with a laptop. The only apparent symptom was inability to establish a wifi connection to any hotspot other than the one in their home. After chasing lots of false trails, the system log led me to the real culprit: failing HD. The OS (Win7 in that case) was doing a phenomenal job of keeping the computer functional, but one critical DLL had been irretrievably corrupted, preventing new connections from being established. The system event log was stacked full of reports relating to bad sectors etc.
So check all the non-informational entries in the log. Even if the hardware itself is fine, there could all manner of bad things happening due to driver issues, and if so, they'll probably get logged one way or another.
Thanks for your input. I have not yet got to the bottom of it but I have ruled a few things out. I have 2 SSD's installed and I ran HD Tune and there were no errors (whether that proves anything I don't know).
I then installed Windows on my 2nd SSD with the same reg errors. Does that rule out an SSD fault?
I then tried the previous OS build which confirmed it WASN'T the new November build.
I get the errors without any driver installation. I am currently removing my 2 HDD storage drives and front 2 case usb hub connectors and the 19 pin usb 3 hub connector and installing Windows again.
Could the motherboard cause this even though it is showing no boot errors or error bleeps?
Anyway I could upload my system file to see if anyone could spot something obvious.
I don't mind if anything has failed, I just want to know what it is so I don't have to play the expensive guessing game of replacing 1 component at a time.
Oh and there is nothing in the event viewer out of the ordinary that I have not seen since windows 7 that I can't resolve and the device manager is also fine.
Edit. I have again installed the latest version of Windows 10 and installed no drivers. (Windows installed Nvidia in the background but that is not the cause).
I have removed several bits of hardware and there is only the rear USB's operational and my mouse/keyboard.
My Titan X is still there but that is fine.
I have attached my System info file if someone could take a look. I will definitely reward anyone who can point me to the culprit.
Below is also one of many keys in DeviceClasses that "error" when trying to open the "Properties" folder.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceClasses\{09485f5a-759e-42c2-bd4b-a349b75c8643}\Properties

Another update. I removed my Titan X which left an empty PC apart from Keyboard/mouse.
I used a new SSD. Tested memory again with perfect results, burned the hell out of my 6700k with not a single error.
Installed Windows for the 50th time. No drivers installed , I ran another Regedit file search immediately as the format completed with the same search hang. It is littered with hundreds of keys that will not open due to errors.
It has to be a faulty motherboard despite it giving me zero issues that I can see. Normally motherboards either work or not but this obviously is not the case here. RMA time
This happens to me also - hangs and then crashes when you click cancel. It doesn't always happen, but sometimes though.
Others also get it - see Regedit.exe search crashing in W10 1511/TH2
You could report/upvote it in feedback - I don't have a more constructive answer, sorry.
How are you installing Windows? From an ISO perhaps? If so, maybe the ISO is bad, try redownloading a fresh copy?
Wow - really looks like a bug then. But other than the search not working, it's seemingly a non-destructive problem?
