Fix a Service Installation Section in this INF is Invalid issue. Follow the steps in this article.

After you connect your Android device to your computer, you find you can’t use the device and don’t see it on your computer. Then you go to Device Manager to check for the driver status. In Device Manager, you see a MTP USB device with a yellow exclamation mark under the category “Portable Devices” (In some cases, Unknown Devices under Other Devices). When you try to update the driver via Windows Update, you get this error message: A service installation section in this INF is invalid . You have no idea how to fix this problem. That’s why you come to this post, right? Don’t worry. You can fix the problem easily with one of the solutions here.

The problem occurs probably due to missing or corrupted USB driver files. Windows has built-in USB drivers, which allow you to connect USB devices to your PC without installing the drivers manually. But if the drivers are missing or having problems, after connecting the USB devices to your computer, you can’t use it directly. In this case, you need to install the drivers manually. There are different reasons causing driver files missing or corrupted. You’re likely to get this error especially if you’re using the streamlined system or upgraded the system to Windows 10.

1. Update the driver automatically
2. Update the driver manually
3. Install the missing driver files manually

Solution 1: Update the driver automatically

Since you can’t update the driver via Windows Update, you can use Driver Easy to update the driver automatically.

Driver Easy will automatically recognize your system, detect any problem drivers, and find the correct drivers for you. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version, it takes just 2 clicks (and you get full support and a 30-day money-back guarantee):

1. Download and install Driver Easy.

2. Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3. Click the Update button next to a flagged MTP USB driver to automatically download and install the correct version of this driver (you can do this with the FREE version).

Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).

After updating the driver, reconnect your Andriod device and check to see if the problem is resolved.

Solution 2: Update the driver manually

To fix the problem, you can try to update the driver manually by selecting the MTP USB device. Follow the steps below:
