  • Inadequate Drive Space: It is a possibility that your Windows drive (which is by default C drive) may not have enough space to install Windows updates, ultimately causing this error. Therefore, make sure that you have at least 16GB free space on your C drive if you are using 32-bit Windows 10 and 20GB if you are using 64-bit Windows 10.

  • Background Programs: When you start up your computer, several applications start running automatically in the background such as anti-virus software, basic system processes, and other previously installed software. These services cause interference in your attempt to install Windows updates, ultimately causing errors.
