I lost my open gl version when i updated to windows 10.

I just updated to windows 10 for the second time yesterday and I tried to play a game on Steam called Bloons TD Battles. I tried to launch the game and it said i was using a different version of openGL. It said I needed version 2.0 or higher, and I was using version 1.1.0. I had upgraded my laptop to windows 10 before, but it started getting slow so I factory reset it back to windows 8.1. I kind of preferred windows 8.1 so i stayed on windows 8.1 for about a month or so. I had finally decided to upgrade to windows 10, and this happens. It didn't do it the first time I had windows 8.1, only the second time. I am running off of intel graphics on the Intel Celeron 1005m. Please help!!

Two choices in order of how complicated they are:
1.Reinstall display drivers. Seemingly only 32 bit drivers exist for windows 10 though. If you are using 64 bit software, installing windows 8.1 drivers should work just as well. Windows 10 has installed ancient drivers for me too upon updating to it.

or.. rather, this link: the earlier was for celeron N series, not m
https://downloadcenter.intel.com/product/75193/Intel-Celeron-Processor-1005M-2M-Cache-1-90-GHz-
And to make it more simple (why not?) Said drivers page links to other driver page with bit more recent drivers. Downside? celeron 1005m isn't listed in supported products. (It will most likely still work just fine. If it doesn't, it aborts at install with "no hardware found" or something like that)
So.. that said, this 3rd link is the best bet:
https://downloadcenter.intel.com/download/25977/Intel-Graphics-Driver-for-Windows-10-and-Windows-7-8-1-15-33-?v=t

2. Reinstall the game.
If game needs it and it was not provided by GPU drivers... game will install it.

Ok thank you so much that fixed the problem, but why didn't it do it the first time i installed windows 10.

Your guess is as good as mine. I would think that the process of updating to windows 10, going back to windows 8.1 and updating to 10 again is not completely bug free.
Which is why most have suggested clean install method (create bootable install media, boot from it, format hard disk, install windows) if you have the time and patience for it. (and patience to reinstall all other software too)

But since things work now, there is no real reason to do so.
Also picking the post that helped you solve the problem as the solution would be nice.

I know I would've but i was just a little curious about it.
