2021 proseries basic- updating installed products versus refresh updates

[JOHNNYCPA]

Is there a difference between  2021 proseries basic- updating installed products versus refresh updates.

I went to installed updates and it states "no updates found" but when I do a refresh updates, I installed the updates?

thanks,

John

Refresh or Repair updates dumps all previously downloaded/installed updates and redownloads/installs them fresh again.
