If you remember windows 3.1, microsoft kept updates on their servers until the 2000s, So I think all your updates will still be available for many more years.I will refrain from name calling and leave out the trolling aspect of my thoughts.
If MS would guarantee update support, through the life of my PC, I wouldn't care. I have a great machine that will likely live passed, the end of life for Windows 7 support. It would be nice to have a current updated package, that did not depend on web updating.
The very same thing is happening to XP as we speak. Every update passed Service pack 3 will be/is no longer available, since MS is dropping update services. This means anyone needing to re-install XP on their old machine is chit out of luck, if they want their system as updated as possible. They will have to settle for SP3, and forget about all those updates that were released since.
Lets not forget about all the Vista machines that lost update services before XP fully died.
