Defrag on SSDs in Windows 10 runs Trim. And it does do that automatically on a schedule if you don't change anything. Actual defragmentation on an SSD is way less useful because SSDs don't have killer seek latencies like spinning rust plates did, and it would be small-scale harmful because of write wear. And your SSD's onboard controller would likely thwart your efforts anyway, because of wear leveling.
TRIM is also important, but it’s a different issue.
(think of it in terms of an SSD being a huge pile of 4MB blocks where each block needs to be completely erased to clear out old content to get a clearer picture)
6. Yes it can. My current Windows 10 system has been installed since March. I disabled the store immediately and no update since then has restored Windows Store or any Store app. You can uninstall the Store (https://github.com/Disassembler0/Win10-Initial-Setup-Script/...) or just disable access/updates through group policy (https://i.imgur.com/ZRxbwNt.png).
6. Random scripts from the Net to "improve" Windows 10? What could possibly go wrong? ;-)
And you're kinda neglecting the elephant in the room: you cannot uninstall apps in Windows 10 at all without using Power Shell. For some reasons Microsoft decided not to include the apps anywhere in GUI, e.g. in Windows Components which if I remember correctly were/was created exactly for this purpose.
In short the apps and how cryptically they are handled is one of the worst "features" of Windows 10. And don't get me on how they are handled in file system: it's a huge effing mess. And how you cannot really access/edit/remove apps data even when you're an administrator.
In short, UWP is an alien technology to Windows 10. UWP should have been a new different OS altogether (and probably that was the plan).
1. Most tech-illiterate people are afraid of using regedit and/or GPO to disable Cortana so the point is valid.
2. Disk fragmentation has become an even bigger issue since Windows 10 doesn't defragment SSD disks.
3. It's not an argument.
4. The article talks about laptops specifically and the issue is still there and it's huge even for Windows 10 which often installs Microsoft drivers which do _not_ work.
5. You must be joking about the startup tab of the task manager. Looks like you've never had this issue or you've only used SSDs in your life. Also discover Autoruns by Mark Russinovich.
6. The Windows Store app canNOT be disabled. Read carefully. Also after each major Windows update all apps are reinstalled.
