The Windows Registry was introduced with Windows 3.1 in 1992 and has been included in every Windows release since. It was designed to streamline the management of application configuration files, evolving significantly by Windows 95. Initially, it featured a single registry file (reg.dat) with a 64KB limit, primarily for basic functions. Windows NT introduced virtualization for legacy 16-bit applications, redirecting INI files into a virtual registry file. Windows 11 includes a hidden option for a darker aesthetic by modifying registry settings. A Registry setting in Windows 10 version 1607 allows file paths up to approximately 32,767 characters, but file names have their own limitations. Modifying the WaitToKillServiceTimeout value in the Registry can speed up the shutdown process. Users can utilize third-party applications like RegScanner or Microsoft's PowerToys for enhanced registry modifications. The Registry allows users to revert to the Windows 10 context menu and add custom entries.
