How to Fix Update Error 0xc1900101 in Windows 11

Microsoft recommends installing the system updates or hotfixes for Windows as soon as they are released. However, sometimes these updates cause whole lot of trouble and result in BSOD (blue-screen of death) which is what scares the Windows users the most.

Last week some Windows 11 users have spent a restless night with the 0xc1900101 critical error. This error started appearing after the installation of some automatic updates on Windows 11. After displaying the error screen, Windows 11 automatically restores the system to the previous stable version.

Even though Microsoft has provided no explanation, this error has been known since the Windows 10 days. Even when upgrading Windows 10 to Windows 11, some users complained about this error. In those cases, Microsoft had advised a number of steps to take to keep this error at bay.

  1. Clean up the system partition. The system partition of a Windows PC is the one on which Windows is installed (usually C:). You have to clean this partition up and make space for more files. If necessary uninstall large installed programs and run applications like CCleaner.CCleaner Easy Clean
  2. Update device driver software. Some hardware components on your Windows PC might have a newer version of device driver software available. You should download and install the newer version for your PC. This can fix the various bugs in the device drivers themselves. You can update driver software using PerfectUpdater software.Perfect Updater
  3. Scan the local storage drives. It could be possible that the local storage drive has a file system problem. In order to fix these problems, we can scan the local storage drives using the CHKDSK command. Basically, you have to open Terminal with administrator level access and give the command CHKDSK /F C: which might require a full system reboot.
  4. Disable antivirus software. Sometimes the installed antivirus or online security software interferes with the file copy mechanism on Windows. This might cause some problems. This problem can easy be resolved by disabling the antivirus software during the Windows Update. Make sure to re-enable the antivirus once Windows 11 is up and running after the updates.

After performing all of these steps, if you proceed with the Windows 11 update, chances are that the update will be installed successfully without any problems.
