News Microsoft starts prompting Windows 7 and Windows 8 users to ‘reserve’ their free Windows 10 upgrade.

[DashMajor]

It's free but would be available only for one year. If someone didn't upgraded till one year he won't be able to upgrade later even if he would be a genuine windows holder.

How many people will hold themselves till next year

How many people will hold themselves till next year

Hardly if they are interested in Windows 10

Then what's the need of wasting 3GB better Satya Nadela and Gates family keep with them.

may be we would come to know later after many users migrated to Windows 10.....or after 1 year is complete.....
