> its free upgrade for 1st year, so why not. 2nd year you’ll have to pay. Those people who say they won’t update unless force to, must be rich, willing to pay when you could get it free

Well, look at it this way.

• I have a Win7 system, and I have some space on an external hard disk.

• I make a full disk image of my Win7 system so I can restore it exactly.

• I then allow the FREE Win10 upgrade to take place on my system.

• I make a separate full disk image of the upgraded Win10 system.

• I restore the saved Win7 image and run Win 7 for the next however many years.

• When I decide I'm ready to run Win10, I restore the saved upgraded Win10 system.

• I let Microsoft push all the accumulated security patches to the machine, since it's possibly years behind.

• Bingo!

I'm running Win10 on MY schedule, not Microsoft's.

Or use Sysinternals Disk2Vhd to convert it to a VHD... Then you can boot to VHD anytime you want and even run it on different hardware!
