Are you people all insane? Code has DEPENDENCIES. You can't just write one patch that works on every version of some code you've ever released. If you start with version 1, and then you fix a bug and you have version 1.1, and then you find another bug that someone who hasn't bothered to install 1.1 wants fixing, what do you do? Make version 1.0.1 and 1.1.1?
Then the next change is going to require you to ship
1.0.0.1
1.0.1.1
1.1.0.1
1.1.1.1
and so on until 64 patches later you have 9,223,372,036,854,775,807 versions you're trying to simultaneously support.
To install a new patch, you must first have installed all the patches that went before, otherwise who knows what will happen. And we have a name for a fully patched version of Windows with every upgrade applied: We call it Windows 10.
