Just because Microsoft sells Windows 7 support doesn't mean you can buy it

INSUBCONTINENT EXCLUSIVE:
In four weeks, Microsoft will push Windows 7 down a flight of stairs, proving that it thinks the decade-old OS has outlived its purpose and
must give way to a sleeker, shinier, newer Windows 10, which, by the way, will live forever.How humiliating for Windows 7, the OS that once
powered 1 billion-plus PCs.Microsoft has made exceptions, as it often does, for its most valued customers
Enterprises can fork over fees for what Microsoft has tapped as "Extended Security Updates," or ESU; in exchange they'll receive patches
that repair critical and important vulnerabilities
The ESU program will run for three years, starting in January, in one-year increments
A company that paid for the first year would receive updates through January 2021, at which time it would decide whether to continue another
year - for double the price of the previous period - or drop out.
