Bad_Company :
Thanks for your responses guys. What games am I playing on this computer ? LOL

the only thing i can play without any problems is mine sweeper :lol: I use this laptop as a secondary computer for watching movies while traveling and have internet access while im away from home. The thing is, its very slow. No matter what i do, its slow. I want to invest 0 amount of money to this old rig. I was not planning to buy Windows 10, but upgrade the Windows7 to Win10 through the Win10 for ussers of assistive technology option that Microsoft has still available, and the after upgrading perform a clean Win10 install from a usb since i have lost my Win7 prod. key. So if upgrading to Win10 is going to improve my experience even by a 5 - 10 % im willing to spend the hours to do this. I just want to be sure that my laptop wont work worst under Win10.
Ah.
Your slowdown may be software degradation so a clean install could help.
I understand how W10 Assistive works, though another option is to:
a) Backup System Image to USB hard drive (highly recommended if you can),
b) create list of programs to reinstall, copy FILES etc to hard drive or USB stick, then
c) restore Windows 7 (should be a factory image there).
d) apply all Microsoft Updates (should be set to automatic, just monitor it so you can then test computer when it's done)
If it's now working fine I'd stay with that.
Windows 10 Assistive:
follow instructions specific to that version, but should work like:
a) create the W10 Install USB (or DVD)
b) boot to the USB/DVD (often need to mess with BIOS boot order.. sometimes need to Google to figure out how to go into BIOS at all such as "F2", "F8" and newer models seem to be POWER + F2 for some.
c) choose to UPGRADE and also keep data and programs (I prefer clean install, but if you can't backup data, or aren't good with computers don't do that... you can also reinstall W10 cleanly if you have problems).
d) make sure correct NVidia driver is installed (used to be an issue, but it should install the right version)
OTHER:
I think you would have two GPU's. An Intel and NVidia, so the program OPTIMUS may be installed via the NVidia drivers.
I've never used it, but AFAIK if you want to play a game it uses the Intel GPU unless the game is on the Optimus list (which you can edit manually but I've never seen it or used it).
OTHER:
My dad's old laptop had VISTA and it got SLOOOW. Really slow. It worked with no obvious errors but it took 7.5 minutes to boot up (yep). When we did a clean install of Windows 8 (which was $40 at the time as an intro offer) the boot time dropped to 60 seconds on the SAME, slow hard drive.
We installed my old, 60GB SSD (we had two, 2.5" bays so used the 250GB HDD as storage) everything was a bit snappier but frankly it worked surprisingly well with just the HDD.
My dad's laptop can do light gaming, and works pretty well (if not too many tabs open) with these specs:
Windows 10 Home x64 (was Vista, then W8, then free upgrade to W10)
2GB system memory
NVidia 8600M GS
Intel CPU (similar to yours)
