How To Find Out Where Itunes Stores Iphone Backup In Windows OS.

Guys I am using Windows 10 OS and I have Itunes installed in my system. I have my Iphone and Ipad synced to itunes via my Apple account, and recently I came to know that itunes stores the backup of iPhones and iPods in windows frequently consuming a lot of space. So can anyone tell me where itunes stores iphone backup in Windows so that I can find them and delete them to release some space?
