I think upgrading the BIOS isn't a reliable solution. But as far as for compatibility, device drivers are somewhat compatible with the new Windows 10. If you look beside the BIOS, what version will...

Will upgrading the BIOS to at least 2013 version, improve performance on Windows 10 on the Latitude D620?

Is there any particular proven evidence of it, that Windows 10 uses old resources on low-end PCs?

I'm asking which version would run better on a limited 2 GB RAM and 1.73 GHz and 80 GB hard drive. And it should be 32-bit only, as no 64-bit support is available in my system.

But with such limited hardware? Windows 10 would run with glitches in it.

I have bought an old and used Dell Latitude D620, and on it, I currently have Windows XP preinstalled on it. But, since XP is very much outdated, I would like to upgrade the Windows version on it....

But I've downloaded it from the Microsoft Official Website. It can't be pirated.
Anyways, you've got to help me please anyone. It's urgent.
Thanks.

I am using Windows 10 Pro (32-bit) on my laptop. At random times, I get a blue screen error (BSOD) during my working hours. :cry:
Please help me in diagnosing this BSOD issue.
