Just installed Windows 7 on an old laptop – 0.75GB RAM single core. It works a treat and is reasonably responsive. It is more than enough for Office type applications and Internet. Well impressed as Vista wouldn’t even look at this machine.
Looks like I’ve just extended the life time of that machine.
Few issues with drivers that I’m still resolving but nothing thats a show stopper.
Best of all it has PowerShell v2 installed.
