Understanding Office update channels, Changing for 365 Home or 2019 Retail

Hi mfessler,

please have a look here, all update channels are described in detail:

Important point: for end user products such as Office 2019 Retail and Microsoft 365 Family only the current channel is available (Microsoft 365 Family allows switching to the preview and beta channel) where the business editions allow for choosing additional channels with different time frames.

So while it might be technically possible to switch the channel, however it is not supported by Microsoft to do so because retail and consumer versions are designed for using the current channel only.

Moreover, it does not make sense either way to switch to a different channel because all the updates being normally installed on a monthly base would simply sum up to a big update when installing twice a year.

I.e. if every update would have 100 MB per month, at the 6. month you would have to install 600 MB of updates. So data volume is no argument for switching the channel.
