PowerToys for Windows 95 were developed by the Windows Shell Development Team. Some of the tools work on later versions of Windows up to Windows XP, but others may interfere with newer built-in features on Windows 98, ME, and XP.[6]

After the success of the Windows 95 PowerToys, the Windows Kernel Development Team released another set of tools for power users called Windows 95 Kernel Toys.[7]

Six tools were included in this package:[8]

• MS-DOS Mode Configuration Wizard Customization Tool allowed users to configure Windows startup files without having to manually edit CONFIG.SYS or AUTOEXEC.BAT;
• Keyboard Remap reassigned functions to keys on the keyboard;
• Logo Key Control configured MS-DOS games so that Windows would ignore the Windows logo key while games were running;

• Windows Process Watcher (WinTop) monitored how much of CPU resources were taken by individual programs;
• Time Zone Editor enabled the user to create and edit time zone entries for the Date/Time Control Panel applet.

According to Raymond Chen, he wrote all of the Kernel Toys except for the Time Zone Editor, which came from the Windows NT Resource Kit.[9]

  PowerToys Power Calculator
  Power Calculator was a more advanced graphical calculator application than the built-in Windows Calculator; it could evaluate more complex expressions, draw a Cartesian or polar graph of a function or convert units of measurements. Power Calculator could store and reuse pre-defined functions, of any arity. For example, a function could be set by cube(x) = x * x * x, and later it could be used in an expression like 5 + cube(4).[11] It did not evaluate every time an operator was entered. Rather, the entire expression must be entered for calculation. In the Numeric mode, it presented a visual keypad, in all other modes the expression had to be typed in. A scrolling text area maintained a history of all calculations. The advanced view allowed declaring and graphing functions, along with a list of all the saved functions. A flyout window provided the option of choosing either a Cartesian co-ordinate system or polar co-ordinates. It could also save a list of variables for use in expression. Unit conversions of the following types were supported: length, mass, time, velocity, and temperature. PowerToy Calc had support for typing calculations using Reverse Polish Notation (RPN). It could calculate up to 500 precision levels beyond the decimal point and supported complex numbers.[12]
• RAW Image Thumbnailer and Viewer provided thumbnails, previews, printing, and metadata display for RAW images from within Windows Explorer.
• SyncToy allowed synchronizing files and folders.
• Taskbar Magnifier magnified part of the screen from the taskbar.
• Tweak UI customized Windows XP's user interface and advanced settings.
• Virtual Desktop Manager allowed switching between four virtual desktops from the taskbar.
• Webcam Timershot took pictures at specified time intervals from a webcam.

• Internet Explorer Find Bar added a toolbar to Internet Explorer that allowed users to search for keywords in a web page. This feature is natively supported by Internet Explorer 8.[14]
• ISO Image Burner burned ISO images to an Optical disc recorder. This feature is integrated into Windows 7.[15] In addition, Windows Server 2003 Resource Kit includes two similar tools (CDBurn.exe and DVDBurn.exe).[16] Although Microsoft has retired this Power Toy, it is available as the unauthorized ISO Recorder Power Toy.
• Shell Audio Player was a Windows Media Player-based compact player which allows playing music from the taskbar.
• Super-Fast User Switcher allowed Fast User Switching or logging on to a different account using the Windows key+Q combination without requiring to switch to the logon screen.
