See Alkerion's post of 04-08-2021 06:05 AM earllier in this thread. All you can do is use the Microsloth tool s/he pointed to to hide the update. Whether this stops the daily installs or simply hides them from users I can't say. But it does not seem to address the daily run of WaasMedicAgent.exe which for many users causes their computers to be unusable for a long time after power up due to the disk IO of WaasMedic.
This experience of the constantly installing driver also seems to afflict users of other printers as well (mostly HP). In Xerox case, I believe it is a collaboration between Microsloth and Xerox to force "Type 4" (Microsloth "App Store app compatible") drivers down users' throats even though these drivers UIs are horribly lacking in functional user control compared to "Type 3". My limited experience with Type 4 drivers installed was that it stopped the attempted update. But I couldn't live with the lack of print preference functionality (choose tray, different paper size / type - including custom sizes I had created - etc.) So I went back to typ 3 drivers, downloaded and ran the wushowhide.diagcab utility to hide the Xerox Extension 7.208.0 update so I don't get either the daily install failed or install succeeded message / error.
I believe that since neither Xerox nor Microsloth will respond to this issue (and there are several threads with more than 1,000 postings on this issue in a Microsloth user forum) it is an intentional push to get you to use drivers suitable for mobile device access to printers at the expense of the flexibility and functionality of desktop application printing. The younger generation for whom cell phones are simply another body part that is in constant demand want all us old farts who still use desktop applications to just go away and die. Therefore all the new "innovation" has to just do simple basic crap that can easily be done with one finger on a small screen. The rest of us...?
