# Bypass Windows ESU
* A project to bypass Extended Security Updates eligibility check for Windows 7 and Windows Server 2008 R2.
- Win7/Win2k8R2 official support and updates ended on 14 January 2020.
However, Microsoft will provide additional 3 years of security updates to the organizations and businesses which have paid the license for the ESU.
More details:
https://support.microsoft.com/en-us/help/4527878
This project helps bypassing this restriction and install ESU updates without purchasing a license, as a proof of concept, non-profit, consumer-targeted.
## Important Notes
* ESU updates are not supported offline (you cannot integrate them),
they must be installed online on live system.
- The ESU eligibilty is only checked during update installation,
therefore, you can choose to keep the bypass installed, or remove it afterwards.
* The bypass will only allow to install the ESU updates,
it will not permit to get the updates themselves via Windows Update.
- You can acquire and download the updates manually from Microsoft Update Catalog site
https://www.catalog.update.microsoft.com
* You can track the updates KB numbers, either check the official Update History page

## How to Use
* Extract the pack contents to a folder with simple path
- Install: right-click on installer.bat and "Run as administrator"
* Remove : right-click on remover.bat and "Run as administrator"
- Note: If you have previous version(s) installed, you don't need to remove it separately,
scripts from latest version can be used to remove previous versions, or install on top of them.
## More Info
- The project supports **all Win7/Win2k8R2 editions**, it consist of two tools that work in similar concept:
for ESU-supported editions, Custom slc.dll will be used
for all other editions, IFEO BypassESU.dll will be used
you can also force the use of BypassESU.dll for ESU-supported editions:
edit installer.bat prior running, and change set ForceHook to 1
* ESU-supported editions:
Client: Professional, Enterprise, Ultimate (including N and E variants)
Server: Standard, Datacenter, Enterprise (including Full, Core and without Hyper-V variants)
## Technical Info

all other exported functions of the original slc.dll are forwarded to the original licensing DLLs.
- IFEO BypassESU.dll:
DLL injection for TrustedInstaller.exe using "Image File Execution Options" technique, which hooks and modify these functions:
