Microsoft Sysinternals
A suite of tools for monitoring processes in real-time (registry reads/writes, TCP/IP port usage, etc), dumping memory of processes, removing NTFS ADS, controlling startup services, and much more!

This suite of tools was developed by Mark Russinovich, and later acquired by Microsoft. I find these tools to be essential for administering Microsoft Windows.
