Microsoft PowerToys Microsoft PowerToys 1.0 for WinXP (939 kb) From NonagsPLUS (Members) (939 kb) Updated: Oct 29, 2001 Homepage Author: Microsoft Description: (Windows XP only) - PowerToys is additional programs that developers work on after a product has been released to manufacturing. They add fun and functionality to the Windows experience. Tools such as Super-Fast User Switcher, Tweak UI, Power Calculator, Image Resizer, and HTML Slide Show Wizard are just a few of the many little tweaks available. Great care has been taken to ensure that PowerToys operates as it should, but it is not part of Windows and is not supported by Microsoft. For this reason, Microsoft Technical Support is unable to answer questions about PowerToys.
