Solution 3 – Reset the Windows 10 Update components

Another thing you can do if you can’t install the upgrade is resetting the Windows 10 Update components. If you’re not sure which components exactly, just follow these instructions:

1. Right-click the Start Menu, and open Command Prompt (Admin)
2. Type the following commands and press Enter after each command:
   • net stop wuauserv
   • net stop cryptSvc
   • net stop bits
   • net stop msiserver

Now, you should rename the SoftwareDistribution and Catroot2 folder. Here’s how to do that:

   • Ren C:WindowssoftwareDistribution SoftwareDistribution.old
   • Ren C:WindowsSystem32catroot2 Catroot2.old

   • net stop cryptSvc

   • net stop msiserver
3. Type Exit in the Command Prompt to close it

Solution 5 – Run SFC scan

Now, let’s turn to the troubleshooting tools. If there’s something inside your system that needs tweaking, and therefore prevents you from upgrading it, the SFC scan could be a perfect solution. Here’s how to run the SFC scan:

1. Open Command Prompt as Administrator.
2. Type in the following command, and press Enter: sfc/scannow
3. Wait for the process to finish (it can be lengthy).
4. Restart your computer

Solution 6 – Whitelist the Windows Update servers

Maybe you’re unable to receive the upgrade because your computer is set to block Microsoft’s update servers. Here’s how to unblock them:

1. Go to Control Panel and open Internet Options.
2. Select the Security tab that you have in the upper menu of the Internet options window.
3. Select the Trusted Sites option from the Security window, and click Sites.
4. Uncheck the Require server verification (https:) for all sites in this zone feature.
5. You will now have a box there that says Add this website to the zone. Type in the following addresses: http://update.microsoft.com and http://windowsupdate.microsoft.com
6. Click on the Add button after you typed in the addresses above.
7. Click on the OK button to save your settings.

Solution 7 – Run DISM

And the last troubleshooting tool w’re going to try is DISM. DISM is basically same as the SFC scan, but is more powerful, so if the SFC scan didn’t get the job done, chances are, DISM will.

Here’s how to run DISM in Windows 7/8:

1. Open the Command Prompt  as an administrator.
2. In the command line, copy-paste these lines one by one and press Enter after each:
   • DISM /online /Cleanup-Image / ScanHealth
   • DISM /Online /Cleanup-Image /RestoreHealth
3. Wait until the procedure ends (it might take up to 10 minutes).
4. Restart your PC.

Solution 8 – Change the size of the reserved partition

Sometimes you won’t be able to upgrade to Windows 10 due to the size of the reserved partition. To fix this issue you have to expand its size, and the simplest way to do that is to use a third-party tool such as MiniTool Partition Wizard Free. Once you install the application increase the size of your reserved partition from 300MB to 1GB for example. If necessary, you might have to reduce the size of other partitions on your hard drive. Bear in mind that this procedure can be potentially dangerous, because you might accidentally delete a certain partition if you’re not careful, therefore extra caution is advised.

Solution 9 – Update your BIOS

Few users reported that they are unable to upgrade to Windows 10 due to their BIOS. According to them, their CPU clock was incorrect, and that was the cause for the 0xc1900200 error. After updating the BIOS, the issue was fixed and Windows 10 upgrade was installed without any problems. We have to mention that this issue can occur even if you have the latest version of BIOS installed, so you might have to install it again just to fix this error. Bear in mind that BIOS upgrade is somewhat an advanced procedure, therefore if you don’t know how to perform it properly, we strongly suggest that you check your motherboard manual for detailed instructions. BIOS upgrade can cause permanent damage if the upgrade process goes wrong, therefore be extra cautious if you decide to upgrade BIOS.
