Hi there! Ever since the launch day of the build 20152 I have been trying to upgrade my system, without success. Today I've tried for the fifth time, via Windows Update section on "Settings". Every single time the process starts, it downloads the whole package again, and afterwards it starts the installation with its several restarts. Unfortunately, every single time it reaches 87% in what seamed to be the last restart of the process, when it turns back on again, it is already rolling back the upgrade process. The error code presented is 0x8007042b. My system is an Acer Aspire ES1-572-37PZ with the latest Bios released by Acer. Looking forward for some piece of advice, thanks in advance. Best regards.
