PyPass-SAB 🐍

PyPass-SAB is a patcher written in Python that allows bypassing and resetting the 100-day trial limit of StartAllBack. This patcher supports versions between v3.5.5 and v3.9.5. Other versions may work but are not tested.

Why did I make this?

Because it's annoying to reinstall StartAllBack every 100 days. I made this patcher for fun and to challenge myself. However, if you want to support the developer of StartAllBack, please purchase a license here.

What does it do?

graph TD;
    A[Start] --> B[Delete Trial Registry Key]
    B --> C[Verify File Hash]
    
    C -- Known Indexes --> D[Create Backup]
    C -- Unknown Indexes --> E[Identify Function Indexes to Patch]
    
    E -- Functions Found --> D
    E -- Functions Not Found --> H[Error: Cannot Patch]
    
    D --> G["Terminate Processes (Explorer, StartAllBack)"]
    G --> I[Apply Patch]
    I --> J[Verify Patch]
    
    J -- Patch Verified --> K[Restart Processes]
    J -- Patch Failed --> M[Restore Backup then restart processes]
    
    M -- Abort --> H[End]
    
    K --> H[End]

Note: The patch does not change the software's expiration date. It only bypasses the license check.

Registry key

A registry key is created when the software is launched for the first time. This key indicates that the trial period has started. To reset the 100-day trial period, we need to delete the following key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\CLSID\{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx}

Note: Each time you run the patcher, the key will be deleted.
