How to Fix MULTIPROCESSOR_CONFIGURATION_NOT_SUPPORTED error in Windows 10

Code 39 - What is it?

Code 39 is a device driver error code that pops up when the Windows operating system cannot load the driver for the hardware you want to use.

This hampers your ability to use the hardware properly. The error code is almost always presented in the following format:

“Windows cannot load the device driver for this hardware. The driver may be corrupted or missing.” Code 39

Error Causes

A device driver is a software program that tells the operating system how to control a particular hardware device. Each hardware device has a different driver.

There are separate device drivers for printers, CD-ROM readers, and keyboards, to name a few.

Many device drivers are already built into the operating system. But sometimes you will need to install a new device driver when you want to use a new piece of hardware device that the operating system is not familiar with, or does not anticipate.

Regardless of whether or not the drivers are already integrated into the operating system, you may still experience code 39, typically because of the corrupted or outdated drivers.

Outdated and corrupted drivers cause hardware malfunction and failure, which trigger device driver error codes like code 39. Other causes include incorrect registry values.

There are some new generation motherboards for laptops and PCs that bring in support for both the Unified Extensible Firmware Interface or UEFI as well as the Basic Input Output System or BIOS. The main advantage of UEFI over the traditional BIOS is the fact that UEFI supports a hard drive that has a capacity of more than 2 terabytes. However, the disadvantage of UEFI is that it only supports the x64 Windows operating system versions and that the hard drive is supposed to use the GPT structure. So if your PC is compatible with and supports UEFI and you want to change from Legacy to UEFI, then you’ve come to the right place as this post will guide you on how you can exactly do that without having to reinstall it. There are two ways to change Legacy to UEFI. You can convert MBR to GPT using either the built-in utilities in Windows or using the Recovery Environment. Before you proceed, make sure that your computer fulfills the following prerequisites:

• Your PC’s motherboard should support both Legacy and UEFI.
• Your PC should be running at least the 1703 Windows 10 version or newer on an MBR partition.

Once you’ve made sure that your computer covers the aforementioned prerequisites, refer to the given options below.

Option 1 – Convert MBR to GPT via Windows built-in utilities

• In the Windows Search box, type “command prompt” and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
• After that, execute this command: exe /convert /allowfullOS
• Now, wait until the process is completed since you can track its process on your screen.
• Once it’s done, go to Settings > Update & Security > Advanced Startup options and from there, click on Restart Now. This will restart your computer and give you advanced options.
• Next, select Troubleshoot > Advanced Options where you will see further options including System Restore, Startup Repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Now select the UEFI Firmware Settings. This will take you to the BIOS. Boot Mode is typically available under Boot > Boot Configuration. Once you’re there, set it to UEFI and then save the changes you’ve made. After that, your computer will restart.

Option 2 – Convert MBR to GPT via the Recovery Environment

• When the message appears on your screen while running Windows Setup, you need to tap the Shift + F10 keys to open Command Prompt.
• Make sure to run Command Prompt as admin and then execute this command: exe /convert
• After that, wait until the process is completed. When it’s done, you have to go to the BIOS just like in the first given option above.
• As mentioned, you can usually find the Boot Mode under Boot > Boot Configuration. Once you’re there, set it to UEFI.
• Now save the changes made and exit as your computer will restart.

In case you don’t know, when you visit a website that uses HTTPS, it also offers an SSL certificate to the browser in order to verify the website’s identity. Although it may contain lots of things inside it, one of them is the URL of the website. So if the certificate does not match the URL to what you entered, you will most likely get the “Server’s certificate does not match, ERR CERT COMMON NAME INVALID” error which indicates that the connection is not private and the site may try to steal your data but worry not, as this post will guide you in resolving this issue. To fix the ERR_CERT_COMMON_NAME_INVALID error, here are some suggestions that might help.

You can also try to cross-check the Windows Hosts file to find out if the website you are trying to open has been blocked, because if it is, then it’s no wonder why you’re getting the ERR_CERT_COMMON_NAME_INVALID error. There are instances when some third-party application modifies the file and adds some websites to the blocklists. So if the website is indeed blocked, you need to remove it from the list.

Option 3 – Use the Google Public DNS

You might want to change your DNS to Google Public DNS as it could also help you in fixing the ERR_CERT_COMMON_NAME_INVALID error in Chrome. To do so, follow the steps below.
