We bought 8 clean computers (even without HDD) with the same hardware and bought eight Windows 7 Pro OEM disks.

Now I prepare one Win7 installation without activation but with all required programs, settings, etc. Then I'm going to clone the image to other computers even without sysprepping. I'm going to change the product key to legal number at COA sticker on each computer and make the activation through the Internet. Will this scenario work?

I know that OEM's license agreement forbids the image cloning and the actions I'm going to do breaks the agreement. According the license agreement I should make the manual clean install of Win7 on each computer. But how Microsoft and other viewers can determine the cloning fact?

All computers are the same and license Win7 DVDs are also the same. However in my case the installation time also will the same (and may be kind of installation code or something else) and this is not good.

Will the Win7 activation work?

Can I be sure that activation will not damage after some time?

Can Microsoft determine the cloning fact during the activation process?

Thank you.
