Extracting and using a modified VMWare Player BIOS or UEFI firmware

-
https://pete.akeo.ie/2011/06/extracting-and-using-modified-vmware.html Extracting and using a modified VMWare Player BIOS or UEFI firmware (updated 2016.05.17 for VMWare UEFI firmware extraction) One day or another, you may want to play with BIOS/UEFI firmware modification. But before jumping into physical motherboard flash alteration, where the consequences of a mishap can be difficult to salvage, experimenting with the BIOS/UEFI in a virtual environment sounds like a sound first step. You have of course the opportunity to do so using  bochs , however the ubiquitous nature and ease of use of the (freely available)  VMware Player  can turn the latter in a much better candidate for the job if you don't really care about the extra features that bochs brings in. This post details how one can extract the BIOS/UEFI firmwares used by the VMWare Player, and how to setup the player to use a modified one. Download and install VMware Player. The current version of VMwar...

Windows 11 internet/account bypass

https://github.com/the-P1neapple/WinJS-Microsoft-Account-Bypass WinJS-Microsoft-Account-Bypass Overview This guide explains a method to bypass the Microsoft Account (MSA) requirement during the Windows 11 Out-Of-Box Experience (OOBE) by using the Developer Console to invoke a hidden local account setup screen. This method was discovered by examining the Windows 11 OOBE source code, which revealed an event listener for a hidden  _localAccountButton . Note A faster method has since been discovered using Command Prompt ( Source ), this repo was made 7 months prior to that discovery. The method I have documented is still the only known method for S-Mode installations. Following these steps, you can create a local account without needing to sign in with or create a Microsoft account. I also have a  Youtube Tutorial  that follows the same instructions below Steps to Bypass Microsoft Account Setup 1. Start Windows 11 Setup Begin the Windows 11 Setup Process. Select your region a...
