+# ZoomWebcamFix
+
+A simple program to unblock webcams blocked by Zoom.
+
+## Usage
+
+This software has two modes of patching.
+
+**Default** - runtime code patching. Requires the software to be open in the background all the time while zoom is running,
+but is more effective when it comes to Zoom's updates.
+
+**File patch** - activates upon pressing *HOME* while waiting for Zoom. Will patch the dll locally, making a copy.
+This method *does not* require any more opening of the program. Once you patch the file, its done and you don't 
+need to do anything else. It *will* reset though on Zoom's updates.
+

+
+## How it works
+
+**Default**:
+
+- Hooks the DLLMain of the DllSafeCheck.dll.
+In onAttach(), this dll registers an NTDLL callback to check for all dlls loaded by zoom.exe and scan them.
+We hook DLLMain and call onDetach() to unregister the callback and make zoom blind for any dlls, effectively disabling the scan.
+
+- Assembly patches the HackCheck() call in WinMain of Zoom.exe, but idk if it does anything anymore tbh.
+
+**File patch**:
+
+- Patches the HackCheck() function to be nop'd, effectively removing it and making zoom call nothing and return true :)
