Resolving Error 0x800f0926: Insufficient Space during Windows 11 Setup

Encountering the 0x800f0926 error during your Windows 11 setup signals a shortage of available storage on your device. To rectify this, consider the following actions:

1. Clear storage space: Remove redundant files or applications to increase available disk space. Utilise the Disk Cleanup utility to eliminate unnecessary temporary and system files.
2. Relocate files: To preserve essential files while freeing up internal storage, consider transferring them to an external hard drive or a cloud storage solution.
3. Turn off hibernation: Hibernation can consume considerable disk space by creating a large file. Deactivate it by launching Command Prompt with admin rights and entering 'powercfg -h off', then hit Enter.
4. Deactivate system restore: System restore points can significantly occupy disk space. To disable it, right-click on 'This PC', choose 'Properties', navigate to 'System Protection', and then select 'Configure' to turn off system restore.
5. Employ a disk cleanup tool: Several external disk cleanup utilities can assist in liberating additional space. Notable ones include CCleaner, Disk Cleanup Pro, and CleanMyPC.

After clearing sufficient disk space, attempt the installation of Windows 11 once more.
