Some utilities that I've discovered today in this reddit post:

• Pulse Diagnostics: a tool to show information about Windows. Nice-looking UI. It includes a simple view to see the Windows log and the list of drivers.

• Replicaro: a backup tool.

• AltRun: a launcher for Windows. Paires well with the amazing Everyghing search tool, which is, by far, the best search tool for Windows. It is fast and lightweight.
