Find my vista calendar or rec' one for Win 7?

Vista home premium is now "windows.old" and Win 7 Pro is now "windows". I cannot recall when or how I got a calendar for Vista. I do a lot of home and office computing and don't remember. Did it come with Vista? And if so, is it buried some place in "windows.old"?

If not, I have searched ZDnet for a new calendar without much luck.

Any recommendations?

I schedule my world in a calendar and really lost without one.

i think vista did have an inbuilt calendar, but then again i only used it for a few weeks,

windows live mail, available for download, has a calendar functionality, but i've never tried it and don;t know what it's like.

personally, i use rainlendar, very useful and customisable.
