How to Repair Error Code 0x8007025D in Windows 10

To help you fix Error Code 0x8007025D, you can try the following steps:

Way 1. Remove the Connected Device

Remove all peripherals on your PC. Connected devices, including USB and external hard drives, can also cause Windows update issues like error code 0x8007025d. A damaged peripheral can interfere with the Windows update installation. Thus, the first tip is to remove all peripheral devices from the target computer and restart it.

Way 2. Reduce the Partition Size and Format It

During the System update process, you must choose the partition where you want to install Windows. Windows 10 installation requires less than 20 GB of free space, while Windows 11 requires at least 64 GB of room.

However, the larger the partition is, the more likely it may be corrupted. Don't panic. As a versatile partition and disk management expert, EaseUS Partition Master Professional can help you resize the system partition and format it:
