Microsoft takes on the evolutionary ideology with each new release of their Windows operating system, with a promise that the number of times one has to restart the computer being upheld all this while. Over the years, the situation has clearly improved, with a bunch of program installations, driver updates, and Windows updates being installed without the need to restart. As for Windows 8, don’t expect a quantum leap in improvement, but Microsoft will instead hope to make restarts which are inevitable happen in an unobtrusive and predictable manner.
For starters, restarts will normally occur just once a month, which is most probably after Patch Tuesday. Needless to say, there are always exceptions to the rule in this life, especially when there are critical out-of-band security updates. Apart from that, you will have a 3-day window to perform a restart if your PC needs to do so, instead of the current 4 hour window. With Microsoft closing the gap in terms of ease of use, do you think there will be a swing back to the PC platform?
