Fix error 0x80070070 Increase the Size of Windows Recovery Partition

Well, if you have enough free space on system partition, it might be the problem of Windows recovery partition.

Windows creates a Windows recovery partition when you install it on a clean disk. When you have problem with Windows OS, you should be able to recover your system with the partition. On an MBR disk, the partition is called system reserved partition, while on a GPT disk, this partition is called EFI system partition or ESP.

When upgrading to Windows 10, the upgrade wizard is trying to copy files to the Windows recovery drive. If the recovery partition is full, the update will fail with error code 0x80070070.

In this situation, the best resolution is to extend the Windows recovery partition via a third-partition software as Windows Disk Management cannot extend that partition.
