Ohook Activation

Overview

• How to use it? Please find the instructions here.
• This activation method can activate all kinds of Office versions on Windows 8 and higher and their Server equivalent except Office 2010 and Office UWP apps.
• This activation method works offline and activates Office permanently.
• This activation method can survive Office repairs, Office updates, and even Windows major feature upgrades. You do not need to reactivate in these cases.
• For the O365 subscription version, you can't get server side O365 specific features such as 1TB storage in Onedrive. However, almost all other features and 5GB storage in free onedrive account would work fine.
• This activation method does not modify/patch any onboard system files, instead it installs a custom SPPC.dll (open source) file for the activation to work. Check further details in below "How does it work?" section.

---

How does it work?

• As illustrated in the above 1st image, in the Official activation process of SPP based Office, Office asks C:\Windows\System32\sppc.dll about the activation status and that file asks the same thing to SPP (Software Protection Platform) C:\Windows\System32\sppsvc.exe and returns the message back to Office.

• As illustrated in the above 2nd image, we modify this behavior by placing a custom sppc.dll file in Office folder without touching system's C:\Windows\System32\sppc.dll file and that custom file always returns the message that Office is activated. This is how ohook activation works.
• You can find the source code of ohook custom sppc.dll file here.

info

• For the O365 subscription version, you can't get server side O365 specific features such as 1TB storage in Onedrive. However, almost all other features and 5GB storage in free onedrive account would work fine.
• Script doesn't convert any product to Volume or vice-versa. All products are activated with their own licence.
• Key preference is given in this order, Retail:TB:Sub > Retail > OEM:NONSLP > Volume:MAK > Volume:GVLK

---

Unsupported Products

• Office on Windows 7 and their Server equivalent
• Office 2010
• Office UWP (Store apps)

Note:

• Theoretically Office on Windows 7 and Office 2010 can be activated with Ohook but these versions require changing Office registry keys and renaming Office file names, that is why we have not added support for it. We recommend to use KMS activation for them.

---

How to remove Ohook?

• In MAS, goto Ohook Activation and apply Uninstall option.
• After that, In MAS, goto Troubleshoot and apply Fix Licensing option. (Optional)
• Done.

• In MAS AIO version, these 2 files are encoded in base64 to make MAS AIO version. In AIO script, instructions are mentioned on how to decode files from Base64 format.
  How to create identical sppc.dll files from scratch?
• Download ohook 0.3 source code file from here
• Extract this zip file to a folder named C:\ohook
• Now download these two compiler archives, mingw32 and mingw64
• Extract both archives with 7-zip in C drive, so that path would look like this,
  C:\mingw32 C:\mingw64
• Open Powershell as admin and enter below command 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;}
• Now open another Windows for Powershell and enter below command to create sppc.dll files,
  Set-Location -Path C:\ohook
C:\mingw64\bin\mingw32-make.exe
• Calculate the SHA-256 of the created sppc64.dll and sppc32.dll files using 7-zip or Powershell, it would be same as mentioned above.
• Done, you can now close that powershell window and correct the date now.
