ohook
2+
=====
3+
An universal Office "activation" hook with main focus of enabling full functionality of subscription editions.
4+
5+
This project is released mainly for our partners. We won't be directly providing any kind support for users.
6+
7+
Installation
8+
------------
9+
Example steps for 64-bit C2R Office running on a 64-bit version of Windows:
10+
11+
1. Create a symlink of the system `sppc.dll` in the Office C2R `System` directory as `sppcs.dll`:
12+
```
13+
mklink "%programfiles%\Microsoft Office\root\vfs\System\sppcs.dll" "%windir%\System32\sppc.dll"
14+
```
15+
16+
2. Copy the hook library as `sppc.dll` to the Office C2R `System` directory
17+
```
18+
copy /y sppc64.dll "%programfiles%\Microsoft Office\root\vfs\System\sppc.dll"
19+
```
20+
21+
3. (optional) In case of some Office editions which show "There was a problem checking this device's license status" banner, you may need to add the following to the `hosts` file:
22+
```
23+
0.0.0.0 ols.officeapps.live.com
24+
```
25+
26+
4. Install a blank key for the edition you want to use. Make sure to check using `slmgr.vbs -dlv all` that the `Grace` license for Office has `Unlicensed` status, otherwise it may interfere. You may fix this with `slmgr.vbs -upk ACTIVATION_ID`.
27+
28+
Please note these steps are an example. As stated before, no direct support will be provided for usage of this method. You should use one of the solutions provided by our **authorized** partners and direct your support queries to them.
29+
30+
Blank keys
31+
----------
32+
The table contains keys for probably the most needed editions.
33+
34+
|Edition|Marketing Name|Key|
35+
|-------|--------------|---|
36+
|O365HomePrem|Microsoft 365|`NBBBB-BBBBB-BBBBB-BBBBG-234RY`|
37+
|O365ProPlus|Microsoft 365 Apps for enterprise|`NBBBB-BBBBB-BBBBB-BBBCF-PPK9C`|
38+
39+
How does this even work?
40+
------------------------
41+
As some would say, "It's trivial."
42+
43+
* The `sppc.dll` copied to the `System` directory in the Office is used instead of the system library.
44+
45+
* The only real license check is done during the startup of the Office applications using the `SLGetLicensingStatusInformation` function.
46+
47+
* The `SLGetLicensingStatusInformation` function can be easily hooked to lie about the activation status.

FAQ
50+
---
51+
### Why not just use a subscription edition with Mondo licenses?
52+
This will be probably the most frequently asked question.
53+
54+
While Mondo 2016 licenses allow all the Office applications to work and support KMS activation, these are only partially updated for newer versions of Office. Thus, the product policy provided by these licenses lack some of the policies found in licenses for newer versions. Since Office product policy mainly consist of entries like `office-UUID`, there is no way to verify which features may not work.
55+
56+
With this method, a correct license for the installed edition is used, meaning every feature should work as intended.
57+
58+
There are also other issues with installing license files from other editions but we won't be bothering with them.
59+
60+
### Why do some editions require the hosts file modification?
61+
After the license check, these editions make a request to the `ols.officeapps.live.com` service to retrieve an expiration date of user's subscription. This is done in order to evaluate should the local license be renewed. Since the service replies there is no subscription associated with the device, a notification is shown. Blocking access to the service prevents Office from being told the truth.
62+
63+
### Does this enable 1TB of storage on OneDrive?
64+
No.
