How to Fix Error Code 0x800f0926: Installation Failure Due to Insufficient Disk Space on Windows 11

Encountering the error code 0x800f0926 during the Windows 11 installation indicates a lack of sufficient disk space on your device. Follow these practical steps to address the problem:

1. Clear disk space: Remove redundant files or applications to make room. The Disk Cleanup utility can help eliminate temporary, system, and unneeded files.
2. Transfer files: For essential files you wish to keep, consider transferring them to an external storage or a cloud service to alleviate space on your device.
3. Turn off hibernation: Hibernation can consume significant disk space by creating a large system file. To disable it, open the Command Prompt as an administrator and execute 'powercfg -h off' (omit the quotes), then press Enter.
4. Deactivate system restore: System restore can occupy considerable space through its restore points. Disable it by right-clicking My Computer, choosing Properties, navigating to System Protection, and selecting Configure to turn off system restore.
5. Utilize a disk cleanup tool: Numerous external disk cleanup tools like CCleaner, Disk Cleanup Pro, and CleanMyPC can assist in decluttering your computer's disk space.

After clearing the necessary space, you should be able to proceed with the Windows 11 installation.
