Hiren’s BootCD PE (Preinstallation Environment) is a restored edition of Hiren’s BootCD based on Windows 11 PE x64. Given the absence of official updates after November 2012, the PE version is currently under development by the fans of Hiren’s BootCD. It includes a carefully chosen set of the best free tools, designed for modern computers that support UEFI booting and need at least 4 GB of RAM.
