If you recently installed Windows 10 and are getting errors such as “Pixel format not accelerated” or “Lack of updated graphics drivers,” you should try updating your graphics drivers. See this page for instructions on how to update your graphics drivers. You can also use drivers from your OEM (e.g. HP, Lenovo, Dell) if applicable, or Windows Update, however the drivers obtained through it may not always support the proper OpenGL (technical term for what Minecraft uses to render the game) to run Minecraft.
Once you’ve obtained the latest driver from your GPU manufacturer, there are some notable differences from previous version of Windows.
On Windows 10, driver updates are automatically installed on your PC whenever your GPU manufacturer (AMD/Intel/NVIDIA) has a newer driver available. On previous versions of Windows, driver updates would not be automatically installed unless Microsoft decided that they would be.
Why this matters
Sometimes, the drivers that Windows Update pushes may not in layman terms, support what Minecraft needs to run.
In this case, you must obtain the latest graphics drivers (software that controls things inside your PC) for your PC from your GPU (hardware in your PC that renders things) manufacturer as explained here. If you’re still not sure who that exactly is, contact the community technical support resources or your computer’s manufacturer (e.g. HP, Lenovo, Dell, etc.) for assistance.
What you need to do differently
Windows Update may overwrite any drivers not obtained from it if it believes that there are newer drivers from Windows Update available. This may interfere with your ability to download drivers directly from a driver vendor. To avoid this, you must let Windows know to not overwrite the driver by uninstalling the driver software and installing the driver with device manager. Please note that this isn’t a sure-fix for the situation as theoretically this policy may change at any time.
Instructions on how to manually uninstall and install drivers with Device manager are explained in the following places:
