Ohook Activation

Overview

• How to use it? Instructions can be found here.
• This activation method activates all Office versions on Windows Vista and later (including their Server equivalents), except for Office UWP apps.
• This activation method works offline and activates Office permanently.
• This activation method survives Office repairs, updates, and even major Windows feature upgrades. You do not need to reactivate in these cases.
• For the Office 365 subscription version, server-side features such as 1TB storage are unavailable. However, most other features, including the 5GB storage provided with a free OneDrive account, function normally.
• This activation method does not modify or patch any onboard system files; instead it installs a custom SPPC.dll (open source) file to handle activation. See the "How does it work?" section below for details.

How does it work?

For SPP-based Office:

• As illustrated in the first image above, during the official activation process of SPP-based Office, Office queries C:\Windows\System32\sppc.dll regarding activation status. That file then queries the Software Protection Platform (SPP) at C:\Windows\System32\sppsvc.exe and returns the status to Office.

• As illustrated in the second image above, we modify this behavior by placing a custom sppc.dll file in the Office folder without altering the system's original C:\Windows\System32\sppc.dll. This custom file always returns a message confirming that Office is activated. This is how Ohook activation works.
• You can find the source code for the Ohook custom sppc.dll file here.

Custom sppc.dll Info

• Custom sppc.dll source code (Ohook 0.5) is available here.
• SHA-256 checksums:

09865ea5993215965e8f27a74b8a41d15fd0f60f5f404cb7a8b3c7757acdab02 *sppc32.dll393a1fa26deb3663854e41f2b687c188a9eacd87b23f17ea09422c4715cb5a9f *sppc64.dll

• In the MAS AIO version, these two files are encoded in Base64. The AIO script includes instructions on how to decode files from Base64 format.

How to create identical sppc.dll files from scratch:

1. Download the Ohook 0.5 source code file from here.
2. Extract the zip file to a folder named C:\ohook.
3. Download these two compiler archives: mingw32 and mingw64.
4. Extract both archives with 7-Zip to the C: drive so the paths look like this:
   • C:\mingw32
   • C:\mingw64
5. Open PowerShell as Administrator and enter the command below to set the time and date:
   Set-TimeZone -Id 'UTC'; $date=[datetime]'2023/8/7 12:00';while($true){set-date $date; start-sleep -milliseconds 10;}
6. Open a second PowerShell window and enter the commands below to compile the sppc.dll files:
   Set-Location -Path C:\ohook
C:\mingw64\bin\mingw32-make.exe
7. Calculate the SHA-256 of the created sppc64.dll and sppc32.dll files using 7-Zip or PowerShell; they should match the checksums mentioned above.
8. Done. You can now close the PowerShell windows and correct the system date.
