I'm a former IT professional. I should sue Microcrap for all the time I've wasted re-installing Windoze and/or waiting for a machine to reboot after making changes.
All total, I've probably spent days and weeks combined waiting for systems to re-boot. Probably months all total re-installing crappy bloatware.
And if you're a consultant, probably most all of it billable. Windows is a money maker. ;-)
