1] Verify the minimum requirement
As earlier indicated, this issue often appears if Windows is incompatible with the specifications of your system.
These are the basic requirements for installing Windows 11/10 on a PC. If your device does not meet these requirements, you may not have the great experience intended with Windows 10 and might want to consider purchasing a new PC.
1 gigahertz (GHz) or faster compatible processor or System on a Chip (SoC)
|RAM:||1 gigabyte (GB) for 32-bit or 2 GB for 64-bit|
|Hard drive size:||32GB or larger hard disk|
|Graphics card:||Compatible with DirectX 9 or later with WDDM 1.0 driver|
|Internet Connection:||Internet connectivity is necessary to perform updates and to download and take advantage of some features. Windows 11/10 Pro in S mode, Windows 11/10 Pro Education in S mode, Windows 11/10 Education in S mode, and Windows 11/10 Enterprise in S mode require an internet connection during the initial device setup (Out of Box Experience or OOBE), as well as either a Microsoft account (MSA) or Azure Activity Directory (AAD) account. Switching a device out of Windows in S mode also requires internet connectivity.|
If your system meets the minimum requirement but you’re still encountering the error, then you can try the next solution.
2] Reset Windows Update cache
The Software Distribution folder in Windows operating system is a folder located in the Windows directory and used to temporarily store files that may be required to install Windows Update on your computer.
Clear the contents of the Software Distribution folder and then try the upgrade again and see if it completes successfully.
3] Expand the reserved partition
As it turns out, this Windows Upgrade error 0xC1900202 issue can also occur because there isn’t enough space on the system reserved partition to complete the operation. If this scenario is applicable, the operation will fail with the error due to space-related issues. In this case, you’ll need to expand the system-reserved partition.
- Press Windows key + R to invoke the Run dialog.
- In the Run dialog box, type diskmgmt.msc and hit Enter to open Disk Management.
- In the window that opens, click on the C:\ Drive and look under for the Partition Map. The first partition will be a 100MB Partition (System, Active, Primary Partition). Right-click on it and choose to Change the Drive Letters and Paths (Click Add and choose Y:)
- Once done, Click Start and type cmd, then right-click cmd and choose Run as Administrator. Once in the command prompt, type the following commands. For the icacls command, use your username which you can find out by typing whoami in the command prompt window.
takeown /f . /r /d y icacls . /grant administrators:F /t <see note below> attrib -h -s -r bootmgr
Once this is done, hold the Windows key and press and open the Y: Drive. Make sure hidden files and folders are set to Show. Go to the Boot folder, and delete all languages other than en-US by using SHIFT + DELETE and then emptying the recycle bin.
- Now in the same Command Prompt window, type the following:
On Windows 8 and above:
chkdsk Y: /F /X /sdcleanup /L:5000
On Windows 7:
chkdsk Y: /F /X /L:5000
This will truncate the NTFS log to 5MB and will leave plenty of space for the install to process. You can then proceed with the installation after the installation has finished, you can go back to diskmgmt.msc and remove the drive letter for the boot partition.
Now, try the upgrade again and see if the issue persists. If so, continue with the next solution.
4] Run SFC and DISM scan
If you have system file errors, you may encounter this problem.
The SFC and DISM are tools in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files.
For the purposes of ease and convenience, you can run the scan using the procedure below.
- Press Windows key + R to invoke the Run dialog.
- In the Run dialog box, type notepad and hit Enter to open Notepad.
- Copy and paste the syntax below into the text editor.
@echo off date /t & time /t echo Dism /Online /Cleanup-Image /StartComponentCleanup Dism /Online /Cleanup-Image /StartComponentCleanup echo ... date /t & time /t echo Dism /Online /Cleanup-Image /RestoreHealth Dism /Online /Cleanup-Image /RestoreHealth echo ... date /t & time /t echo SFC /scannow SFC /scannow date /t & time /t pause
- Save the file with a name and append the .bat file extension – eg; SFC_DISM_scan.bat and on the Save as type box select All Files.
- Repeatedly run the batch file with admin privilege (right-click the saved file and select Run as Administrator from the context menu) until it reports no errors.
- Restart your PC.
Try to upgrade again and see if the issue is resolved. If not proceed with the next solution.

5] Directly download the Windows 11/10 ISO
