Windows 10 is undoubtedly the most popular version of the Windows OS in recent times and therefore many users want to upgrade their OS. You may also want to upgrade to the licensed version after the free period ends. However, many users complain that they have come across this Windows 10 update Error code: 0xc1900200 while trying to upgrade to Windows 10. This prevents them from upgrading to Windows 10.
Fortunately, however, this error can be corrected and you can successfully upgrade to Windows 10. Let's see how.
Method 1: unplug any external hard drive
If there is a USB device plugged into the system while upgrading to Windows 10, this is probably the reason behind this error. USB devices or external hard drives are, although very useful when trying to back up data, but these devices can interfere with the Windows 10 update process.
Also, if you have connected a USB Bluetooth receiver, this can also interfere with the update process. Therefore, it is recommended that you do not connect any USB devices while the Windows 10 update process is activated. Make sure that no type of external hard drive, i.e. pendrive, smartphone (via USB connector), printer, etc., is not connected during the update. This should completely fix the problem.
However, if you keep getting the error then you can try the second method.
Method 2: resetting the Windows 10 update components
Step 1: Go to the Start button on the desktop and type Symbol of the system in the search field. Right-click on the result and select Run as administrator to open the file Symbol of the system with administrator rights.
Step 2: A Symbol of the system window, execute the following commands one by one and press Log in after each command:
net stop wuauerv
net stop cryptSvc
net stop bits
net stop msiserver
This will break the specific Windows 10 components that need to be reset.
Step 3: Open the Symbol of the system again in administrator mode, as shown in Step 1 over it.
Now, run the following commands and hit Log in whenever:
Ren C:WindowssoftwareDistribution SoftwareDistribution.older Ren C:WindowsSystem32catroot2 Catroot2.older
This will rename two folders, Software distribution e Cartroot2.
4 phase: Now, run the following commands in the file Symbol of the system and hit Log in after each command:
net start wuauserv
net start cryptSvc
net start bits
net start msiserver
This will launch BITS, Cryptographic, MSI Installer, and Windows Update Services. When done, close the file Symbol of the system window.
This should fix the update problem, but if the problem persists then try the third method.
Method 4: unblocking Microsoft Update servers
Step 1: press the Windows + R keys together on the keyboard to open the file run I send. Now Write inetcpl.cpl in the search field and press ok.
Step 2: A Internet options dialog box, go to Safety tab and select the file Trusted sites icon. Now, click on the file Sites button.
Step 3: A Trusted sites window, uncheck the box next to Request server verification (https 🙂 for all sites in this zone.
4 phase: Now, enter the following website addresses in the file Add this website to the zone one by one and click Inserisci next to it each time you enter an address:
After you have finished adding the two websites, close the window. Then back in Internet options window, click ok to save changes and exit.
Now try to upgrade to Windows 10 and there should be no errors. But, if you still see the error, try the fourth method.
Method 4: Resize the Reserved Partition
The reserved partition on each system is set to a certain size and when that size is not big enough, you will not be able to upgrade to Windows 10. At that time you can see the error. So you need to increase the size of the reserved partition and for that you would need a third party partition wizard. There are quite a few known free partition wizards.
You can use the file Free MiniTool Partition Wizard or any of its reputable alternatives. After installing the partition wizard, you can increase the size of the reserved partition, substantially, for example, from 400MB to 1GB. You may also need to reduce the size of the other partitions on the hard drive.
Just be very careful when resizing the partition. You may end up deleting a specific partition, which can be disastrous for your system. Therefore, make sure you are very cautious.
That's all. These methods should resolve the Windows 10 update error code: 0xc1900200 and you can proceed with the update without any problems.
