Many good products and services have "gone by the way" over the last 15+ years.
Everyone is affected.
Not promoting Microsoft per se but sometimes we have to go with the "proverbial flow".
Even Microsoft does not have control of everything: hardware, software, security requirements, AI, etc...
Consider a Microsoft 365 Office subcription. You can share the subscription with up to 5 other people. That is what I do for family members.

Good news being that you have Windows 11 (versus XP orsome other older OS version).
Bad news (my personal opinion) is that AI is quickly and intrusively getting into everything.
Everyone wants the "One ring to rule them all". Co-Pilot included.
Consider trying Microsoft 365 but be sure to back up all important data beforehand. (Backups should always be being done anyway.)
And watch out for Outlook - Classic vs New. New can be problematic.

Just my thoughts on the matter.
There may be other ideas and suggestions.
