Reinstalling my Windows machine and wanting to preserve iTunes backups Is there a way to preserve the backups from all my iDevices stored into the iTunes folder - photos, audio notes, SMS etc. and move them to the new Windows installation. 

Is this possible? How?
Depending on the iOS version of your devices, I suggest backing up to iCloud instead. If you have iOS 5 installed, find iCloud in Settings, select storage and backup, and backup all of your devices.

If you do not have enough room for all of your devices under iCloud or if they don't have iOS 5, you can follow this guide to back them up.
