After you upgrade your computer to Windows 10, if your Microsoft Network / Ethernet Drivers are not working, you can fix the problem by updating the drivers. It is possible that your Network / Ethernet driver is not compatible with the newer version of Windows.

How to Update Device Drivers
There are two ways to update drivers.
Option 1 (Recommended): Update drivers automatically - Novice computer users can update drivers using trusted software in just a few mouse clicks. Automatic driver updates are fast, efficient and elimate all the guesswork. Your old drivers can even be backed up and restored in case any problems occur.
OR
Option 2: Update drivers manually - Find the correct driver for your Network / Ethernet and operating system, then install it by following the step by step instructions below. You’ll need some computer skills to use this method.
Option 1: Update drivers automatically
The Driver Update Utility for Microsoft devices is intelligent software which automatically recognizes your computer’s operating system and Network / Ethernet model and finds the most up-to-date drivers for it. There is no risk of installing the wrong driver. The Driver Update Utility downloads and installs your drivers quickly and easily.
You can scan for driver updates automatically with the FREE version of the Driver Update Utility for Microsoft, and complete all necessary driver updates using the premium version.
Tech Tip: The Driver Update Utility for Microsoft will back up your current drivers for you. If you encounter any problems while updating your drivers, you can use this feature to restore your previous drivers and configuration settings.
Download the Driver Update Utility for Microsoft.
Double-click on the program to run it. It will then scan your computer and identify any problem drivers. You will see a results page similar to the one below:
Click the Update Driver button next to your driver. The correct version will be downloaded and installed automatically. Or, you can click the Update Drivers button at the bottom to automatically download and install the correct version of all the drivers that are missing or out-of-date on your system.
Option 2: Update drivers manually
To find the latest driver, including Windows 10 drivers, choose from our list of most popular Microsoft Network / Ethernet downloads or search our driver archive for the driver that fits your specific Network / Ethernet model and your PC’s operating system.
If you cannot find the right driver for your device, you can request the driver. We will find it for you. Or, try the automatic option instead. Exploring biology in the laboratory pendarvis pdf to word.
Tech Tip: If you are having trouble finding the right driver update, use the Microsoft Network / Ethernet Driver Update Utility. It is software which finds, downloads and istalls the correct driver for you - automatically.
After downloading your driver update, you will need to install it. Driver updates come in a variety of file formats with different file extensions. For example, you may have downloaded an EXE, INF, ZIP, or SYS file. Each file type has a slighty different installation procedure to follow. Visit our Driver Support Page to watch helpful step-by-step videos on how to install drivers based on their file extension.
How to Install Drivers
After you have found the right driver, follow these simple instructions to install it.
- Power off your device.
- Disconnect the device from your computer.
- Reconnect the device and power it on.
- Double click the driver download to extract it.
- If a language option is given, select your language.
- Follow the directions on the installation program screen.
- Reboot your computer.
There is one particular scenario where you could be faced with this when booting a VM using Hyper-V. The most obvious way you can immediately notice it is that when using Virtual Machine Connection to remotely control a virtual machine, you do not have mouse integration.
(Note that in Windows Server 2008 RTM, Hyper-V Beta integration components are in-box. You will see similar lack of mouse integration on future releases of Hyper-V where you have updated the physical machine but not updated the virtual machine image. Once we have a new release of Hyper-V available, I’ll post more on that.)
The issue is very specific to where you have a Windows Server 2008 x86 (not x64) virtual machine originally built using Virtual PC or Virtual Server. It should not apply to Windows Vista SP1 (currently not supported in Hyper-V Beta). Opening Device Manager (Start devmgmt.msc) inside the virtual machine will provide the first sign that you are hitting the issue. As you can see in the screenshot below, under the Computer node, it says “Advanced Configuration and Power Interface (ACPI) PC”.
If you scan further down Device Manager to the bottom of the “System Devices” and double-click on VMBus (which has a yellow exclamation mark against it), you will see in the device status area that the device cannot find enough free resources that it can use. (Code 12).
The reason for this is similar to the issues stated in yesterdays blog post about having the correct HAL installed. For VMBus and other components necessary for synthetic device support in Hyper-V to load correctly, the HAL running in the virtual machine must be an APIC HAL. Fortunately, Windows Vista and Windows Server 2008 have a new boot option to force HAL detection during boot, which is off by default. The easiest way (command line junkies excused) to change this setting is through the “msconfig.exe” tool. If you select the boot tab and then hit advanced, you’ll notice a checkbox marked “Detect HAL”. After selecting this checkbox and hitting OK, you must reboot the virtual machine.
Once the virtual machine is restarted, open up device manager again. This time you will notice that under the computer node, it now reads “ACPI x86-based PC”.
A few final comments. First, the “Detect HAL” checkbox is sticky, and causes boot to be very slightly longer (so slight in fact, I can’t notice a difference using a stop-watch). If you do not intend returning this virtual machine back to Virtual Server or Virtual PC, you could turn the checkbox off and reboot.
To clear up a point from my previous post, I said that “In theory it is possible to swap the HAL, but not in a Microsoft supported manner (except on Vista and Windows Server 2008 – that’s a post for another day)”. Hopefully that is a little clearer now. You may be wondering, if you clear the checkbox, and while the virtual machine is configured with an APIC HAL, what happens if you take the VHD back to Virtual Server or Virtual PC? In this case, the boot will not complete, even in safe mode. The way to resolve this is to ensure the check box for Detect HAL is checked before shutting down the virtual machine under Hyper-V.
You can also set or clear the checkbox in a slightly smarter way if you don’t have a Hyper-V machine available to boot the virtual machine to toggle the checkbox directly while the VM is running. The answer is in BCDEditt. You could loopback mount the VHD and use bcdedit to alter the boot configuration store offline. I haven’t tried it with a mounted VHD, but the parameters would look something like “bcdedit /set {current} detecthal yes” replacing {current} with an appropriate store. There's something to investigate and a blog post for another day…
Cheers,
John.
