well, i have a ssd (40gig) with windows 7 ultimate 64 bit on it, with some programs on it. it runs in my main laptop. i can take it out, put it in my other laptop, or my desktop, and it boots like its setting up the performance screen whenever i change the drive to another pc. after that screen, it loads windows, intstalls the drivers for the motherboard and other things and restarts. then it reboots and it works as if it has always been in the computer. i know it should not do that. but for some reason its working like this so i use it as a test drive on multiple computers, although reactivation is requires but is never a problem. weird i know, butit s happening. try it and see what it does
Windows 7 has better REPAIR procedure.It's faster and does the job great.That OS has been programmed that it contains most of the neccessary drivers for many types of hardware and Microsoft made it on the way that OS adapts to new hardware and that all neccessary drivers are already included in it's drivers database on the HDD and functional automatically WITHOUT the need to perform REPAIR every time when hardware is changed in order to copy neccessary drivers from the CD or DVD disk.
On Windows XP the situation is different (opposite) because REPAIR needs to be performed every time when the hardware is changed because XP does not contain ALL the neccessary drivers in it's installation drivers database on the HDD for other hardware and for that reason REPAIR must be performed in order for CORRECT drivers to be copied of the XP CD disk on the HDD to make XP OS work properly.Of course I am talking about main drivers neccessary for OS to even work properly EXCLUDING the drivers such as: graphics,sound,LAN,wireless LAN and so on...which need to be installed manually.UNLESS if XP already contains them or if you made your own disk containing those drivers...
Of course in some cases even Windows 7 will require you to perform REPAIR using it's DVD disk if it doesn't work at all on changed hardware,but it's a lot less neccessary than it is on Windows XP.
Reason:
Windows XP: does not copy all the drivers from it's installation disk in it's DRIVERS database on the HDD during it's installation...
Windows 7: does copy all the drivers from it's installation disk in it's DRIVERS database on the HDD during it's installation...
Of course this is just the DRIVERS part.Windows 7 also has better registry adapt procedure so it does the job great when moved to a different hardware while on XP that does not happen and instead you get BSOD in most cases and for that reason REPAIR is neccessary on Windows XP.
REASON:
Even with neccessary drivers OS will not work if those driver's values are not correctly written in the registry which OS uses to communicate with the drivers.
Plus a lot more blablabla...
And of course at the end like you already said the REGISTRATION is required.Simply because Windows has been made on the way that when hardware is different/changed that you must REGISTER it in order to tell it that the OS really is legally bought FOR THAT HARDWARE.
Reason:
Microsoft on that way protects their own property and earns more money.Because if you buy their OS only ONCE and then it works on ALL computers,laptops and netbooks then people would not buy it so often and Microsoft would not earn a lot of money...AND THAT IS EXACTLY WHAT MICROSOFT DOES NOT WANT...
Not even me...that is why I make my software's protection based on hardware type
Cheers!
