Backwards compatiblity. It sounds great.
Windows can run the previous version of Office. But running the current version, alongside say, Office 2007, is a major pain in the ass.
Maybe you just need to run the old version of Outlook, because your IP phone system or ERP software has some plug-in that was never written for the next version and isn't compatible.
Maybe you need to run a version of Access that's so stinking old that you have to use Windows XP in a VM.
Now, to make things worse, the database connectors for that version of Access are so outdated, that it's holding the entire company back on MySQL 5.5 because if you upgraded, your Access application wouldn't work anymore.
Not to mention, all that code you wrote 20 years ago in VBA is insecure as all hell. Unencrypted connections, ripe for SQL injection, plus that version of Access can't work with large datasets or return large results. Dammit!
