This is the core of the driver patching process. You are essentially tricking the installer into thinking your Windows 7 is a compatible operating system.

Yes, the same driver package that works on Windows 7 64‑bit also works on and Windows 11 (64‑bit) . However, driver signature enforcement is even stricter on newer Windows versions. You will need to temporarily disable it using the F8 boot menu (on Windows 10/11 you may need to first access Advanced Startup Options from the Settings app). Alternatively, boot into Test Mode using bcdedit /set testsigning on .

⚠️ : Disabling driver signature enforcement, even temporarily, weakens the system’s protection against malicious kernel‑mode code. You should only do this if you are absolutely certain that the patched driver you are installing comes from a trustworthy source. Always scan any downloaded driver archive with an up‑to‑date antivirus.

The third-party INF does not contain digital signature information.

The IT9910 can struggle with audio-to-video synchronization on Windows 7. To fix this: Go to Sound Settings > Recording . Find the "Digital Audio Interface" (IT9910).

Since the manufacturer (ITE) often lacks a direct consumer download page, these third-party repositories host the necessary 64-bit files: Treexy Database : Provides the ITE IT9910 Grabber (HD) driver package compatible with Windows 7 64-bit. DriverIdentifier : Offers a specific version for Dell OptiPlex systems that is known to work on various Windows 7 64-bit machines. 3. Manual Installation (The "Patched" Method)

Click , select the IT9910 Grabber Device model from the list, and click Next .

Select from the menu.

While "patched" drivers often refer to community-modified files to bypass digital signature requirements or enable features on unsupported OS versions, you can find the standard 64-bit drivers through these common repositories:

You will likely also find a .cat file in the driver folder. A Catalog ( .cat ) file acts as a digital signature for the driver. Once you modify the .inf , the signature is technically broken.

Which (like OBS or PotPlayer) are you planning to use?
