I wonder the rationale behind stating "not activated" in a panel where you type stuff by hand. but nevermind.
Back to topic, who would prefer to keep windows 2000 over Win 7 or 8 nowadays? Same for Win7 in 10 years.
Been running XP for the last 10+ year and only mad the switch to 7 1.5+/- years ago on new hardware.
As it looks I'll be staying with both XP on older hardware, until that hardware fails, and 7 on my newest hardware, until that newer hardware fails, and then try staying with 7 with newer hardware.
That is unless MS DUMPS the Stupid Pad/Phone interface for desktop and notebook computers. Then we'll see.
considering we don't know the changes to come over the next 10 years i honestly don't know why you are trying to get hardware to last that long, 10 years ago ddr1 was the norm we are now 3 generations past that.
in a few years time storage manufacturers will go beyond sata 600 as a standard and move to higher rates as well as storage capacities increasing to the hundreds of tb's instead of just a couple, there is a reason windows 8 supports up to 300+ tb hdd's.
as to xp, frankly it's out of date and showing it's age, with an outdated kernal and lacking support from even microsoft themselves and no update to newer standards like html 5 or even support for what adobe are capable of doing it's a dead os and i mean that in the truest sence.
windows 7 will be good for a few years yet but i think we'll start to see reasons to change even when we don't want to, more than likely because of the latest and greatest hardware but thats somewhere down the road yet.
