Windows 10 Upgrade: 80240020 & C1900200 Error Fix!

 In All posts, Articles

Hi Folks!

Many of you hare excited to update your Windows 7 and 8 machines with the latest operating system from Microsoft: Windows 10. But it would seem a few are reporting that they receive either a 80240020 error or C1900200 error. (You can see what’s holding your Windows 10 install back by going to Windows Update > View Update History > Click any failed updates and look at the error code)

How to Fix the 80240020

1. Go into “C:\Windows\SoftwareDistribution\Download” and delete everything in that folder.
2. Now, run the command prompt as an administrator. Type in “wuauclt.exe /updatenow”.
3. Go to your Control Panel > Windows Update and your Windows 10 should start re-downloading from scratch.

Simple!

How to Fix the C1900200 (At little trickier) 

This error is likely showing because your system reserved partition is full, thus preventing Windows 10 from upgrading. Let’s see if we can clear just a little space for Windows 10:

Method 1 Remove Language Files from System Reserved Drive

  1. Press win+r and type diskmgmt.msc
  2. Click on your C: drive
  3. Below the list of drives there will be a partition map, the first partition will be Data or some such, listed at 100MB, right click on it and go to change drive letters and paths -> add -> now choose Y: for the drive letter
  4. You’ll need to take “ownership” of the new drive (Y) if you want to see the hidden files inside. Download this awesome tool from Rizonesoft here: https://www.rizonesoft.com/ownership/
  5. Run the application and choose “Install”
  6. Go to your new Y drive, right click and “Take Ownership”
  7. Next make sure to change “show hidden files, folders…” and uncheck “hide protected operating system….” otherwise when clicking into the Y drive you’ll see only the boot file and no language files!usbrepair4
  8. Now open explorer (win+e) go to the Y: drive under computer, go into the Boot folder, and delete all languages other than en-US. Languages are in the form xx-XX. Make sure to shift+delete and not just delete so they don’t go to the recycle bin. Empty the recycle bin afterwards just in case.
  9. Now go to the How to Fix the 80240020 above (top of page) and follow those steps to restart the Windows 10 install. That’s it!

 

 

Method 2

  1. Press win+r and type diskmgmt.msc
  2. Click on your C: drive
  3. Below the list of drives there will be a partition map, the first partition will be Data or some such, listed at 100MB, right click on it and go to change drive letters and paths -> add -> now choose Y: for the drive letter
  4. Right click the CMD.EXE start menu icon and choose ‘Run as Administrator’. Or, to open an admin cmd prompt, in win8 you can press win+x and choose command prompt (admin), in win7 you have to create a shortcut for cmd.exe, then go to compatibility in the shortcut properties, and choose run as admin.
  5. Type: Y: <enter> in the cmd window
  6. Run these commands:takeown /f . /r /d yicacls . /grant administrators:F /t <see note below>attrib -h -s -r bootmgr
  7. NOTE: for the icacls command you can use your username instead of administrators, to find out your username type ‘whoami’
  • Now open explorer (win+e) go to the Y: drive under compuer, go into the Boot folder, and delete all languages other than en-US. Languages are in the form xx-XX. Make sure to shift+delete and not just delete so they don’t go to the recycle bin. Empty the recycle bin afterwards just in case.
  • now go back to the admin command prompt, and type this command:chkdsk Y: /F /X /sdcleanup /L:5000
  1. this truncates the NTFS log to 5MB, it can be very very big, not leaving enough space for the install. At the end of the output it should tell you that you have at least 50MB of free space on the partition
  • proceed with the windows 8.1 installation
  • once booted into 10 and set up, you can go back into diskmgmt.msc and remove the drive letter for the boot partition
