I looked at getting a Tektronix MSO5000 series scope before opting for Agilent, and that runs Windows 7. As in the complete Windows 7 with a start menu and internet explorer and minesweeper and everything. The scope had a mini mATX PC inside with Intel Core i-something processor and removable 2.5" hard drive. It was pretty cool being able to surf the web on your scope, but the big thing that put me off it was the inclusion in the box of a CD with "Windows 7 Recovery Disk" loudly printed on the sleeve. Call me old fashioned, but if a £20000 scope needs it's OS recovering, ever, then I'll give it a miss.
Maybe you should have considered that the main reason why recovery disks are included are not because Windows needs to be reinstalled every 6 months (which was a silly myth even in Win95 days), but because these scopes contain hard drives or these days SSDs which do have a very finite life time, and it's a nice thing when a commodity part breaks down (which can replaced for cheap) that you don't need to call the scope manufacturer's support to reload the software (for a notable fee of course) because your only copy of the scope software was on the dead hard drive.
I think half the problem with Windows isn't the OS itself in its pure form,as you would install if you were a PC builder,but with the
"crippled" OEM versions which substitute silly,clunky, "HP" or "E- Machines",or whatever alternatives to many of the Windows inbuilt features.
As these don't have much relationship to the MS versions,most of the available information is useless.
I particularly hate it,when they don't give you "administrator " status.
Our desktop is an "E-Machines" (OK-El Cheapo) device,which "crashed " repeatedly.---no OS software disc provided,of course!
Eventually,in desperation,I forked out for a MS Windows 7 disc,& did a clean re-installation.
The beast hasn't missed a beat since!
