I haven’t bothered since the laptop has a low quality display and a dying battery, and I have so many other tablets and laptops in the house.Judging from my own half-similar Celeron N3350 in power saver mode (@ 1.1GHz), I don't think it's the CPU performance itself that's the issue, but the IGP. C2D-era IGPs are pretty useless under 10, have horrible driver support and just not enough performance to run the newer Windows DWM compositor properly. Not to mention not being DX11 compatible, which is more-or-less required for a good 10 experience IMHO.
You could get by on 7 since you could always fall back to the older GDI+ compositor. Which pretty much anything can run. Windows 8+ removes that fallback, and so relies on the DWM compositor at all times. Which older GPUs simply lack the horsepower to run.
Have you tried a lightweight Linux distribution, just to see how it runs?
You may be right about the iGPU. Pentium SU4100 has GMA 4500MHD, which incidentally was a reason I bought that laptop, as it has hardware h.264 decode. However, I wonder how Celeron N3350 scores in Geekbench 5 in power saver mode.
