OK. Worth the experience.
Taking advantage of this, I don't remember how or why it got like this, but the first time I installed the kernel extend in Windows Vista on this notebook from 2007, Windows 10 kept appearing in the compatibility tab. I will post here.
I had removed Vista from this notebook to test Windows 11, which ran on it quite well. I had to disable a bunch of stuff, but it ran. But at the time it was with SSD. I went to help someone and sold the SSD to him. Then I put mechanical HD again. So I took the opportunity to install the new Vista Kernel (October 2022). And it's running great.
Here I am running:
Photoshop CC
Office 2010
Firefox 102
sony vegas 17
Camtasia Studio 8.0.0
It works well because it is an AMD Turion 64 x2 processor (2 cores and 2 threads), with 4Gb of DDR2 RAM and a Radeon 2400 GPU.
It has some CPU peaks, but in general it has very low consumption.
Wanted to try running Opera GX on it. If it works out, it'll be great. However, not even downloading the Windows 7 version does it install itself.
Edge, on the other hand, is just curiosity. Since I don't even use it on Windows 11. I prefer Opera GX or Seamonkey (which I customized to be a modern version of Netscape).
Maybe I'll use Netscape (Seamonkey) on it.
I'll keep doing tests.
Thank you for the tips.
