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Outdated and corrupted drivers cause hardware malfunction and failure, which trigger device driver error codes like code 39.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.
Further Information and Manual Repair
Below are some of the easiest and most effective methods to resolve Device Manager error code 39 on your PC.
To follow and implement these methods, you don’t require any technical knowledge or expertise. Simply follow these instructions to fix the error right away.
Method 1 - Fix with a Simple Reboot
There is a possibility that the error code 39 is caused by some fluke within the Device Manager or your BIOS.
If that’s the reason, then a simple PC reboot can resolve the issue immediately. Therefore, before you try anything, it is advisable to restart your system.
If it works, then that is great, but if it doesn’t, then don’t worry, try other methods given below to fix this problem successfully.
Method 2 - Uninstall and Reinstall Drivers
If the error code 39 is generated due to faulty or outdated drivers, then simply uninstall and remove them and then reinstall new driver versions. There are two ways to remove faulty drivers.
Method One
- One is, to go to the start menu, click on Control Panel, and then Add/Remove Programs.
- Remove the program and the driver you think is causing problems. This will thoroughly remove all traces of the faulty driver.
- To reinstall, follow the same steps but this time install the new device driver version.
Method Two
- The other way is to go to the start menu, type Device Manager in the search bar, and then press enter to continue.
- In the Device Manager, find and locate the problematic device.
- After that, double-click the category of device that you wish to uninstall. Let’s say, Windows is unable to load the graphics card driver.
- This means you will have to click on the Display Adapter category in the Device Manager to uninstall the graphics card.
- After you have successfully uninstalled, Windows will prompt you to confirm device removal.
- Simply click OK to confirm and proceed. To activate the changes, restart your PC.
- To reinstall, go to the Device Manager, click on the Action tab and then select the option ‘Scan for Hardware Changes.’
This method, although effective in resolving error code 39, can be time-consuming. To avoid the hassle and save time, try method 3.

Microsoft has released Windows 11 as a public beta release for all the people that are not willing to be in the insider program.
Beta release as of this moment is identical to Insider Preview build 22000.100. and updates will not roll so fast as in insider preview and it is marked as unstable release, same as insider build.
I would not install Windows 11 beta on the main PC since some drivers still have issues and may lead to some blue screens.
Be aware that the beta build will have all Windows 11 system requirements including TPM 2.0. This is a big difference from insider build which can be installed on systems lacking official requirements.
So basically if you have a spare PC that could run Windows 11 install it so you can see what it brings and feel it so you can make a decision will upgrade once it is released later this year.
