I moved to Microsoft 365 Office Family installation. Same as un-installation it halted nearly at the end of the process and stayed idle for 3 hours. I checked in Control Panel > Programs and Apps > Installed Apps. Microsoft 365 Office was shown but the task was idle in Task Manager. I restarted the PC and this time Office displayed it’s all set.
