Thanks for catching that second "5" entry, Count...too late to change it now...
3) *Disable Prefetch Key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters (because I have an SSD)...
5) Turn off disk defrag for drive c:\ (because I have an SSD) ...
Well, there's a prefetch parameter here, too--not just the Superfetch component--wear and tear on SSDs is measured by write/rewrite activity--that is the only way to measure the lifespan of these drives, everything else being equal, since there is no mechanical component. When you turn off the Superfetch service, these registry keys are not affected by doing that: enable Prefetcher, & enable Superfetch. Prefetch is a separate operation from Superfetch, and since I'm there I go ahead and turn off Superfetch as well, as you just Modify the parameter from 3 to 0 for both. Takes all of three seconds for the entire operation. Simply turning off the Superfetch service does not change these registry entries/values.
You are certainly right in that there is divided opinion about how helpful it is in turning off Superfetch and Prefetch with an SSD--but my own experiments in my system--limited, certainly--show no performance advantage at all that I can perceive between Superfetch/prefetch on and off with my SSD (while huge performance differences are perceivable using mechanical HDs, of course). So, I turn them off--as that undoubtedly increases the longevity of the drive to some extent as it stops any data-write activity related to the Superfetch/Prefetch settings being active. If they don't affect the performance of these drives when booting and running Windows, they aren't necessary, imo, while they demonstrably increase drive wear. Just my personal view, of course ...
Defragging an SSD unnecessarily is unnecessary, eh?...

It doesn't seek like a platter drive, so defragging it like a platter doesn't serve a purpose, contiguous blocks mean nothing to an SSD--defragging could even slow it down, theoretically, and also contribute to unnecessary writes when the OS defrags automatically as it sees fit--it's the unnecessary activity that I object to, and that much isn't theoretical. My Samsung software tells me that I have enacted approximately 15.4 TB's of writes to the drive--which theoretically will handle ~75 TB's of data writes before it begins to fail. That leaves me about 6 more years of drive use at my current useage rates--In practice, though, the drive *might* last for 150 TBs--or 12 more years!...

That's why limiting data writes would seem an advisable course to take.
That's my reason for limiting these things with an SSD as a boot drive. Yes, some people don't think it matters, but I think the logic behind turning these unnecessary drive writing activities off when they only serve to unnecessarily increase the writes on an SSD drive is sound. I mean the OS is smart enough to handle TRIM correctly--but not these other activities--for some reason, despite the fact they exist for mechanical platter drives exclusively.
Your suggestion about the shortcut arrow is one I can definitely commiserate with! But I use no tiles (ugh!--No Metro fan here!), and I don't use the Windows store (I mean, for what?...

), and I have no issues with file ownership yet--knock on wood! I'm sure we all have our own lists of personal peccadilloes...
