During Windows Upgrade if the process stops, and shows Windows Upgrade Error 0XC1900122 and 0XC1900123, it means there is a problem with the amount of disk space required by the process. During Setup, there is the amount of time that allocated to resolve the issue, if you take more than, the setup process just halts.

You may get an error message which will include:

1] MOSETUP_E_INSTALLDISKSPACE_TIMEOUT The install disk space issues were not resolved within the required time limit.
2] MOSETUP_E_DOWNLOADDISKSPACE_TIMEOUT The download disk space issues were not resolved within the required time limit.

In both the cases, you either make sure you have enough disk space before you start or, you create enough disk space in time.
