thanks @LazyDodo (LazyDodo)
I tried doing the same thing, and that blew up a tiny bit, to share resources the creating thread needs exclusive access to the main context currently bound to the main thread. WM_opengl_context_create has a comment about it, guess i'm not the first one to try and fail at this :)
Well my latest refactor in this area was to assure that a context is only made current on the thread that will use it (first time made active in GHOST_ContextWGL::initContext). So maybe I overlooked something.
It's a classic race condition, here's what's up

Hmmm then it seems that 8c77c3653996516ba152eade2c27980ae20a1198 is wrong in some way.
@Clément Foucault (fclem) I'm not sure if this is related, but now I get the same error when press F12 using Eevee. The error is not all the times (maybe 90% of times).

Only in Windows and maybe in Mac.
The problem is only in Windows and Mac:

Thank you Philipp for your reply.
To answer the question pertaining to the folder, I installed Blender probably last year and gave up. The file folder was on my computer, where I tried several times using the installer. I tried "change" and "repair" functions a few times. I also uninstalled Blender and tried again from the beginning.
As for the other question, I can only find 2.79b version from Blender's website. Can you please send a link to other versions, so that I can try them instead?
Please dont claim these yourself, someone will pick it up.
oh wow , there was quite a bit more of the pbuffer stuff left, thanks for the cleanup @Germano Cavalcante (mano-wii) !
- Remove all uses of Pbuffer (on win32).

- feedback: remove now unneeded pbuffer
I don't quite understand the importance of setting a PixelFormat to dummy contexts or offscreen contexts (or even to the context used in Blender). You must understand this better than I do.
But if the problem is only that the "SetPixelFormat can only be called once for any given HDC", why not just prevent it from being called again if the hDC already has a PixelFormat setted?

Is this still an issue with 2.79b?

I'm having this same issue in 2018 (Blender crashes when selecting Cycles or selecting the System tab under user prefs). Does anyone know if there was a fix for this other than disabling screens? I have a two monitor setup on a desktop PC and I don't really want to be disabling a monitor every time I use Blender.
All my drivers are up to date and I'm using Blender 2.79.

I tried this on win 7 gtx 550ti master hash d5c1c0b, every things seems okay, I run the script till my Mem was 50.90M i don't remember how many times but more than needed :)
OK, seems like a Windows issue then (I'm on linux as well).
Someone here on Windows can reproduce?

You have this option turned on:

Archiving then (feel free to reopen if problems persist -- but it seems this is not something blender has anything to do with...)

- Our installer never writes to system32 , all required files are contained in the blender folder.
- even if we did (which we don't!!) we never released an installer with the vc14 dll's , that's only available in the experimental compiler zip files on the buildbot.

Since last asking for information it has been 7 or more days, due to the policy of our bug tracker we will have to archive the report until the requested information is given.

@Christian Hoffman (Dramock) : is this still relevant? Has above link solved this?

Woah, I found the file you were talking about and removed it. Everything seems to be running fine now. I have no idea how that file was in there if it was not supposed to be.
I don't believe so, I've been having this problem since I first download blender yesterday, I'll check if I can find that file.
Looks like you're running on mesa? did you by any chance drop a opengl32.dll in your blender folder?
Alright, I've attached the file and I will look at the information displayed from the debugging, thank you.
Let's see what graphics card blender is using on your computer.
In the Help tab click on Save System Info and then share the file generated here. (Maybe that gives some clue of what's going on).
Another thing that would help investigate would be by opening blender from the Command Prompt adding the arguments --debug-gpu. The prompt will display some information that may be useful.
This occurs with a standard cube (about 2-5 fps). If I load in a character model it gets even worse( below 1 fps)
Apr 11 2018
Is this with the standard cube or with a very large scene?

I also encountered this problem. My mechanical keyboard has some broken switches and I made a new windows keyboard layout for german and replaced the letter "Ö" with "L", as "L" and I didn't need "Ö".

I've also had the same problem.
Blender would load, and then when clicking on the splash screen, it would be "disabled"/"locked".
After some time, Windows notifies the software is taking to long to respond.
