scientiae: I recommend a third-party registry manager, like Piriform's
CCleaner. It will safely uninstall software and clean up the registry in seconds. It also performs secure wiping of any discs attached to the system, but this takes a long time (days).
While we're talking about Win10, I must register my disgust with Edge. I think it's meant to be some sort of new-fangled browser.
Whatever the reason for its deployment it is not equivalent to a normal PDF viewer, which it supplants by default; for one egregious example it prevents the selection (and therefore copying) in-line text! (Probably some sort of copyright management initiative.)
The menu has hidden the commands I use the most (like zoom) so they require a traversing multiple levels to adjust the view. Also, the controls are all centred on the pointing device, too, so normal Adobe keyboard commands, like PgUp, Home and End, don't work. I suppose a touch screen would benefit, if I ever thought to use one.
(For the last couple of months Micro$oft has been trying to push the Edge app as an "essential security" update for this (Win7) machine and I have had to continuously tell it not to dare to download this steaming pile of useless frippery. It also keeps telemetry data.)
Also, there is geekuninstaller which I have found works wonders at uninstalling software, rooting out tricky to find leftovers, and force removing that which M$ in their wisdom think we shouldn’t uninstall. First and foremost of those being any browser from M$ including edge. Almost any other browser is better. In fact all M$ products have been getting worse each iteration since Gates left, Hotmail is now a mess of advertising color blobbing, multi tab, spam collector. Office has a joke “open” file format, rubbish ribbon, now gone online only, and is incompatible with anything. Windows game offerings have always been an affront to the world (who can forget such wonders a GFWDead). Win vista and 8 were awful, 7 being a suprise. Win 10 is better, but with all the surrounding issues like telemetry, bloatware etc. (And we won’t talk about phones!).
