Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Before you try to uninstall anything else Office related, find out what your computer manufacturer set up for reinstalling Office Starter 2010. I have seen it where some manufacturers require that you do a full PC recovery just to get Office Starter 2010 back, while others provide a selective applications recovery that will put just Office Starter 2010 back onto the computer after it's uninstalled.
If you have to do a full PC recovery, that would certainly be a PITA :-(
