Which version of Windows is best for my laptop?

[hp1000-1b10au]

I have Hp 1000-1b10au laptop. Currently I have Windows 7 32-bit in it. I want to know should I install Windows 10 or 8 or keep it just as it is. I love to play games and use it basically for playing games. Currently it runs many good graphics games like Saints Row-4, Inversion, outlast, batman arkham origins, etc. without any lag on medium settings. Will I get better performance if I upgrade?
I want better speed also. I currently use Avira Free Antivirus. Which new Antivirus should I use?
My spec are:-
Amd radeon hd 6480g graphics
Amd a4 apu 3300mx
2gb Ram
5400 rpm hardisk.
Please reply
Thanks. ............

Your model laptop comes preinstalled with Windows 7 or Windows 8.  But, HP does not provide any drivers for Win10.

This is a serious issue because, if you install Win10 on it, you will be relegated to using the generic drivers that Microsoft supplies, with the result that some of the hardware will not funcion properly, most notably, the video.

So, I would advise strongly against upgrading to Win10.

Also, in many cases, HP only provides 64-bit drivers for Win8 laptops as most of those were shipped with 64-bit hardware.  So, if you upgrade to Win8, you may then have a similar driver problem as with Win10.

My own advice is to stay put with Win7.  IT works, and there is no guarantee that forcing an upgrade to Win8 is going to improve anything, or even work!

Thanks WaWood.,
I have already used Windows 10 for nearly 1 week.
You are right that many drivers were missing., but after the Windows updates installed I observed that everything was back to normal. There were no missing drivers.
So, There is no driver problem but I want to know that will I get good performance on my poor laptop? .
Thanks for helping Bro. ........

My own experience, running a desktop with both Win8.1 and Win10, is that Win10 is snappier and takes less disk space than Win8..  So, my guess is that you should see better performance running Win10.

Here are some troubleshooting steps you can try for improving performance: http://support.hp.com/us-en/document/c04770630
