in our house, my wife's pc is the only thing non-mac we have. Multiple iPads, we both use iPhones and my desktop is an iMac. We have turned off all filesharing completely, as far as I can tell, but her VivoNotebook (most current but it happened to a couple of HPs already) keeps wanting to download and install multiple operating systems. Everything from windows 95 to windows 11 and every version from Home to Enterprise, and the updates for our iPhones, iPads, and my iMac runs Big Sur (because it didn't make the cut-off by one month LOL) and hasn't had much in the way of updates recently. Does anyone have any ideas at all as to what could be the problem? PC "specialists" (used loosely) seem more concerned with passing the buck to everyone else than solving the problem. I can provide any specifics if you ask. Thank you in advance and please don't egg me for bringing up a PC-ish issue here getting kind of desperate. this started about a year and a half ago with her first PC and it's getting strenuous, to say the least.
