Good to-do list and calendar programs for Windows?

I think this Windows function might help. If I find something better I'll let you know.

You could try Google Keep (for todo lists) and Google Calendar (for calendar and scheduling). Access is through your browser, but I find it useful as it syncs between my (Android) mobile and PC. If you use Chrome browser, you can also find them on the Chrome web store. Needs a Google account, obviously :-)

Good luck.

I use Outlook's Calendar function.

Sticky notes, hooray.

Or, install Rainmeter and find or create a simple memo bar on your desktop.

I make tons of notes and lists because I'm really forgetful, my favourite program for this is Evernote.

It's like a slimmed down version of MS Word. It's for Windows but also has apps for iOS and Android. You make a free account and your notes get synced to a cloud server where you can access them from your phone, your tablet, your computer. It's really handy when I'm on the computer and I remember I have something to add to my shopping list, so I just add it on my computer but it gets synced straight to my phone so its on there when I go to the shops. You can make checklists with it too and organize your notes into separate notebooks if you want (eg I have one for just everyday notes and one for pasting recipes I find on the Internet that I want to keep) . It's not the simplest tool for the job but it's still easy to use and has a lot of functionality.
