I've downloaded Windows 10 onto my laptop, but left Windows 7 Professional on my main computer. I am currently on BA on the laptop, but this morning it froze when loading markets into Guardian and then I had the 'blue screen of death'
I only downloaded it because Microsoft kept pestering me. I thought well, I'll probably have to download it eventually. Doh. I've also had to sort my printer out as that stopped working too.
