Microsoft's Secret Stash - 10 Best Unknown Windows Utilities
No power user runs Windows with just stock settings; the plethora of third-party PC utilities is an embarrassment of riches. But what about Microsoft's own contributions? Tools like SyncToy and Pro Photos are pretty well known, but there's actually a wealth of advanced tools buried in the Sysinternals section of Microsoft's Technet site for IT professionals.
The Sysinternals site hosts some of the most powerful Windows utilities you can find. Yet surprisingly, not too many people know about them, since TechNet is primarily a System Administrator resource. Whether you're looking for more powerful ways to find out what's under the hood of Windows, need help creating VHD images for use with virtualization hosts, or just wanting to play a joke on your co-workers, these little-known utilities have you covered. We cherry pick and go over the features of the ten most useful Sysinternals tools, and then show you the best of the rest. Read on to dive into this awesome stash of Microsoft-sanctioned tools and tweakers for Windows XP, Vista, and 7!
What's going on when you start your system or run a particular Window program? Process Explorer knows. This tool enables you see the interaction between Windows programs, components, and programs.

To get information about any program, double-click it to open a multi-tabbed properties sheet. How much CPU time and I/O is the program using? Click the Performance Graph tab to find out.

Other tabs reveal process threads, security settings, environment settings, and file (Image) information, TCP and UDP ports used, and additional performance details.

Use the menus to customize color highlighting, select how much information to display, and to search for particular handles or DLL files. Process Explorer provides an unparalleled "inside view" of your system.

No matter how fast your computer, Windows services and startup programs help slow it down at boot time. Autoruns digs far deeper than Windows MSConfig to show you exactly what's running when you start your computer.

The default Everything tab shows you every startup program and service. To help you manage what's going on in a more digestible fashion, use the tabs to view specific items: Logon, Explorer, Internet Explorer, Scheduled Tasks, Services, Drivers, Winsock Providers, Print Monitors, LSA Providers, Network Providers, Sidebar Gadgets, Codecs, Boot Execute, Image Hijacks, AppInit, KnownDLLs, and Winlogon.
By default, Autoruns in limited access mode, even for administrators. If you want to enable or disable an option, you might see an Access is Denied error message. Click Run as Administrator, and after Autoruns restarts, make your change.

You can use Autoruns to clear away a lot of startup clutter (for example, if you're running a proprietary print monitor for a printer you don't have installed anymore). However, be wary of seemingly "duplicate" entries. For example, in the KnownDLLs tab on a 64-bit system, you will see the same DLL name in two places: the System32 folder and the Syswow64 folder. Don't disable them!
