Hi Michelle,
Do you even try any of these useless standard "solutions" before copypasting them to every question?
The problem is the update KB3197954 itself, not suddenly broken drivers, deleted system files, disk fragmentation or any other stupid issue. Anyone I've asked to confirm the issue could easily reproduce that inactive window scroll isn't working in Excel until KB3197954 is uninstalled. You could also spend 1 minute of your time to launch Excel and see that to scroll any window you now need to click that window, while outside Excel or without installing the update everything works fine.
Looks like it mostly affect Excel 2016 but some users I've asked reported broken Inactive window scroll in older versions of Office too.
Sorry for possible anger and bad English, but users are expecting real help and advices, not botlike answers "For absolutely any problem use this list of actions, if not helps - proceed to clean reinstall"...
