Elcomsoft System Recovery UEFI Support

Thursday, June 16th, 2016

As you may already know, we’ve released an update to Elcomsoft System Recovery, a tool allowing to reset or recover Windows and Microsoft Account passwords by booting from an external USB drive. The new build allows creating bootable USB drives for devices exclusively relying on UEFI bootloaders. Why was this change needed? Read below for an answer!

UEFI Boot Support

If you need access to Windows protected files (and files containing password hashes are always protected), you will either require administrative privileges or must boot a separate copy of Windows from a separate boot media. Elcomsoft System Recovery has always come with the ability to create such bootable media.

As computers evolved, industry moved to 64-bit computations. During the last decade, CPU manufacturers migrated completely to 64-bit architecture. Some years later, it became obvious that legacy BIOS was no longer relevant in the new age. BIOS was superseded with UEFI.

To maintain compatibility with legacy operating systems, most systems of that time period came with support for legacy boot mode (BIOS emulation, “compatibility mode”) enabled out of the box. As operating systems evolved, manufacturers started gradually phasing out legacy support. Today we have reached the point where many new devices (2013 and newer) come without any sort of BIOS emulation at all.

Elcomsoft System Recovery comes with a customized bootable Windows PE environment. By booting from this media, customers can gain access to existing Windows installations even if they don’t know the correct password. For a long time, Elcomsoft System Recovery was relying on legacy compatibility mode to boot. This is no longer an option. The increased share of devices shipping without BIOS emulation or legacy boot support required us to adapt.
