This is the portable edition of RegToy - a software application that includes numerous utilities for customizing the behavior of your operating system.
Since the tool doesn't come with an installation package, you can save RegToy to a USB flash drive or any other removable device, store it on any computer and directly run its executable file.
Thus, you can always carry RegToy with you when you're on the move. Plus, no leftover items can be found in the Windows Registry or on the hard drive after program removal.
The tool is wrapped in a user-friendly UI where you can make several tweaks concerning the system, hardware, startup and shutdown mode.
Therefore, you can force the core Windows system to be kept in the memory and not paged to the disk, and disable compression or encryption on NTFS volumes. But you can also establish the secondary level data cache of the CPU, specify a timeout for hung logon sessions during the shutdown procedure, disable MMX processor extensions and Direct3D, as well as enable USB autoplay.
Other tweaking tools center on the Windows Explorer (e.g. turn off the Details Pane), desktop and icons (e.g. remove the shortcut arrow on shortcuts), taskbar and start menu (e.g. force the use of the classic start menu) and context menu (e.g. disable the ability to right click on the desktop).
Additional customization features revolve around the system information (e.g. edit OEM details), logon (e.g. set an image as the wallpaper before logon), security (e.g. disable User Account Control), location of Windows installation files, folder options and Windows Defender, just to name a few.
RegToy also corrects wizard issues, provides a basic function to easily locate its features, records changes made by a particular program, edits Windows Registry entries, and can restore all settings to their default values.
The complex software application runs on a moderate-to-high amount of system resources. It didn't freeze, crash or pop up error dialogs during our tests. Taking into account its long list of tweaking utilities, RegToy is sure to please first-time and power users alike.
