Short description of error
When I open blender, whether I open the program or open a blend file with the program, the popup says Warning! Legacy WGL is unable to select between different OpenGL versions.

Exact steps for others to reproduce the error

Open blender.
On the cmd screen that appears at startup, it says Warning! Legacy WGL is unable to select between different OpenGL versions.

Your GPU is too old. You may be able to still use it if you update your drivers.

Ah. Ok.

Will there be any issue such as slower render times or malfunctioning 3d viewport? will it affect rendering even though I use cpu rendering?

If you are able to get it to open with a newer driver it should not affect you.

If I stay with this driver, will these be affected(this gpu is old(for vista), and has no "official" drivers for 7)?
Also, will I not be able to use future versions of blender?

No, the OpenGL required version is only going to increase. Blender 2.8 will likely be OpenGL 3.X. Currently, you have to have at least OpenGL 2.1 see the requirements page for more information https://www.blender.org/download/requirements/

Please explain how Blender running on a GPU that supports OpenGL 2.1 and ran fine on Windows 7 gives this error on Windows 10 Anniversary edition if GPU is too old? Therefore this is not a satisfactory answer.

Contacted Nvidia and they insist, and I agree that GPU is 'not' too old, and ran Blender just fine on Windows 7. Nvidia also stated that since it ran on Windows 7, and that OpenGL support is hardware based, driver is not the cause, and the application (Blender) is the offender.

I question this because Blender ran fine with same card on Windows 7. Because only three things changed on my system. Windows 7 to Windows 10 Anniversary upgrade, NVidia drivers were updated (clean install) from Windows 7 to those for Windows 10, and Blender was updated since previous version failed, this points to some kind of software change, none of my other applications are affected; and I run some intense graphics applications, including Blender!

To me, it seems as if this is a Windows 10 problem then; but, I can find nothing to support this. So what we have right now is Nvidia pointing at Blender.org, Blender pointing at GPU and Windows 10 saying "what me worry?" Until this issue is resolved, this should remain open. We need to determine exactly where to point the finger. I'll try to coordinate. If Blender and Nvidia can work to help me understand why I should point my finger at Windows, I will work to help resolve this issue. I miss using Blender, and it appears many do have this problem, but are unorganized. (Probably because they don't know where to look for help; and to date, I've seen no one claim any uninstall and re-install of graphics drivers works! I know, I've done it twice already myself with everything except Windows 10 because with Windows 10, that's not possible.

I will attempt to display OpenGL Viewer 4.4.4 image of OpenGL support of version 2.1 by my "NOT" too old GPU.

This is weird thing, time to poke out ogl expert @Mike Erwin (merwin) :)

Mike, do you have clues why glview and blender has such a different idea of supported ogl features? Is it core vs. compatibility contexts?

@Chip Cooper (Cyberchip), at the meantime, did you doublecheck you've got drivers installed from nvidia site? Windows 10 has a tendency of preferring it's own update thingie to install drivers and those are not always correct drivers.

System Information for above system with same issue!

Yes, downloaded directly from Nvidia Support site. Definitely not the issue as far as source goes.

where did that come from? that shouldn't be there

It was an attempt to fix this issue; one had suggested I place it there... I will remove that... (had forgotten). Will get back on this.

BTW, here's another piece of software claiming same issue; but, claiming it's a Windows 10 issue.
https://forum.kicad.info/t/opengl-2-1-or-higher-is-required-on-windows-10/1299

Geez, I feel like such an idiot. Right after I updated to Windows 10 Anniversary, I had this issue, and found a reference saying I needed this to fix the problem, and to put it directly into the directory. What I forgot to do was remove it, after I found out that didn't solve the problem.

Apparently, I had fixed the issue, except for the fix that didn't work! Gotta laugh... even the best of us... (sigh).

Bottom line, all is working (Thank you all!)

My apologies!

I believe I can now claim to be a Lazy Dodo... after all, like many old timers like me... I've forgotten way more than I currently know, been around that long doing this stuff.
Thanks Lazy Dodo! (sigh).

Just realized that the old ghost of .DLL Hell, and workarounds still coming around to bite me in the ass! Maybe I *am* getting too old to keep doing this stuff... :-( I can't believe I forgot to roll back after a fail.... I used to be soooo adept....

Guess I'll just be grateful... hmmm, Dodos have eagle eyes... learned something new.
