PowerShell-based PoC for CVE-2021-36934, which enables a standard user to be able to retrieve the SAM, Security, and Software Registry hives in Windows 10 version 1809 or newer.

In specific versions of Windows 10, standard users have read/execute rights to files in [SYSTEMROOT]\System32\Config directory, which is where the Registry hives reside on disk. One can't however, simply navigate to the directory and copy/paste as the hives are loaded and into memory upon system boot and are locked. A standard user can retrieve the hives from Volume Shadow Copies if they exist.

The success of this exploit resides on the fact that Volume Shadows Copies exist... without them the code isn't useful.
