It's a job that someone at Microsoft probably got dismissed for suggesting, creating a SP2 for Windows 7. unprofitable, since they would rather everyone use Windows 10.
Why make it convenient for the Windows 7 users, let them waste time downloading over 200 patches instead wrapping all of them into a Service Pack. Bugger it all up with Windows 10 upgrades infiltrating the Windows 7 updates.
This is why I love Microsoft, if it wasn't for all the problems people have, trying to use the Windows Operating system, I would have to find another way to make a living.
