# System Requirements

* x86-32/x64 Windows 7/8/8.1/10 (client, some methods however works on server version too).
* Admin account with UAC set on default settings required.

# Usage

Run executable from command line with following keys (watch debug ouput with dbgview or similar for more info):
* 1 - Leo Davidson sysprep method, this will work only on Windows 7 and Windows 8, used in multiple malware;
* 2 - Tweaked Leo Davidson sysprep method, this will work only on Windows 8.1.9600;
* 3 - Leo Davidson method tweaked by WinNT/Pitou developers, works from Windows 7 up to 10.0.10514;
* 4* - Application Compatibility Shim RedirectEXE method, from WinNT/Gootkit. Works from Windows 7 up to 8.1.9600 [See Important Note];
* 5** - ISecurityEditor WinNT/Simda method, used to turn off UAC, works from Windows 7 up to Windows 10.0.100136;
* 6 - Wusa method used by Win32/Carberp, tweaked to work with Windows 8/8.1 also;
* 7** - Wusa method, tweaked to work from Windows 7 up to 10.0.10136;

* 11* - WinNT/Gootkit second method based on the memory patching from MS "Fix it" patch shim (and as side effect - arbitrary dll injection), works from Windows 7 up to 8.1.9600 [See Important Note];
* 12 - Windows 10 sysprep method, abusing different dll dependency added in Windows 10 (works up to 10.0.10514).

Note:
* Methods (1), (2), (3), (5), (8), (9), (12) require process injection, so they won't work from wow64, you need either Heavens gate or use x64 edition of this tool;
* Method (4) unavailable in 64 bit edition because of Shim restriction;
* Method (6) unavailable in wow64 environment starting from Windows 8. Also target application unavailable in Windows 10;
* Method (11) implemented in x86-32 version;
* Methods (4), (11) targeted by MS April patch by removing autoelevation from sdbinst. Install KB3045645 for Win7/8 and KB3048097 for Win8.1 to apply security fix. More info: https://support.microsoft.com/en-us/kb/3045645, https://support.microsoft.com/en-us/kb/3048097;
* Methods (5), (7), (9) based on Carberp(WUSA) and Simda(ISecurityEditor) no longer works in Windows 10 starting from build 10147.
