(Just a thought) If they didn’t create it, they wouldn’t have to fix it!
Microsoft seems to do the opposite that IBM did decades ago.
Microsoft seems to add what they think customers want then have to remove it or fix it when users find all the things that don’t work or never use.
IBM would advertise a system, see how many people wanted it, then started designing it (known as Vaporware).
There is little reason why I should not still be able to use Windows 7. Even apps like Quickbooks has updated their software to new requirements that negated running on certain older systems. Quickbooks is what accountants know as a ‘double entry method’ of accounting which has not changed much if at all since it was created in the 1290’s and codified in 1494. So if the method is still used on paper but the software to do it keeps changing to ‘make it better’, you have to wonder if it is just changing to make a profit with new versions.
