What's with Flash player in Internet Explorer?! ...and Firefox, and...

I had it already and I came to this sort of conclusion/question (at any rate, still a puzzle): Apparently if IE does not work properly (no PDF viewing, no Flash player, always asking for an update, even when Firefox or Chrome work fine doing the same, etc.) that is a sign of Windows problems. It could be spyware (?) How about Flash10u.ocx instead of Flash10e.ocx? What about the difference between the Shockwave Flash Object and the Flash Player? It seems to be that these are two different names for the same "add-on", not sure. In addition, there's Activex Version: 10.3.181.34 (as of this date) and Plug-in version 11.0.1.152. In addition, there is the Flash Player Settings Manager in the Control Panel, but that it's only for the 32-bit version. In other words, sort of confusing. Was this the reason why Steve Jobs (r.i.p.) literally censured this technology, back in 2010 ("we know that Flash is the number one reason Macs crash") and I would add the number one reason why Internet Explorer crashes and/or performs poorly sometimes.  Well, at least Adobe has a page on the subject. Solving this puzzle may be the key to a number of issues in Windows, and that goes for other Adobe products. Oh, yes, and for the other browsers!
