Step 4: Update ALL the drivers available

This api-ms-win-core libraryloader l1-1-1.dll is missing error can also happen when you have the mismatched/missing/outdated drivers on your computer. It can be difficult to put finger on which one is offending our system so we need to update ALL the drivers available to help resolve the situation.

There’re two ways you can update your device drivers — manually or automatically:

Update your drivers manually – To troubleshoot the issue, you can update all available drivers manually ONE BY ONE until you pin down the exact driver at fault. Firstly you’ll have to go to the manufacturer’s website, search for the most recent correct driver for the devices. Be sure to choose only drivers that are compatible with your variant of Windows system versions. Then download & update them all by yourself.

Update your drivers automatically  – Updating all the drivers manually is no picnic. If you don’t have the time, patience or computer skills to update your drivers manually, you can, instead, do it automatically with Driver Easy. 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.

  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. You can upgrade to  the Pro version and click Update All to automatically download and install the correct version of ALL the drivers that are missing or out of date on your system.

    You can also click Update to do it for free if you like, but it’s partly manual.

  4. Hopefully by this time you’ve upgraded to Windows 10 successfully.

Step 5: Install ALL Windows updates
