(a) 50 Kbps sounds good to me. Who is your ISP? See whether they have speed tests...

Verizon Speed Tests
It says my router to them & back is about 100 Mbps each, & from my computer to them & back is 50 Mbps each. I think that's my plan -- 50's. It seems quick enough to me.
(b) "your site has been timing out"
This Microsoft Community will behave oddly at times. I saw someone else complaining in another thread. I have a few complaints too. Normally, click the browser's
Refresh button to fix it -- but do a Ctrl-A & Ctrl-C first to copy out text you may be working on. Sadly, if there's a picture in the copied text, this site won't take it back after the Refresh is done -- it used to be better.
(2) "the mess that One Drive has made of my files"
I'd like to hear more about that. A clean install should behave well with OneDrive. But I only did it once a few years ago & didn't pay much attention seeing no problem. I think I lost no files & definitively did not get triplicates.
Right-click OneDrive, select Settings.
(a) At the Account tab, is there still just one account?
(b) Click the Choose Folders button -- are there duplicate folders
or even differently named folders that you know hold the same files?
(c) Did you add folders to OneDrive prior to the clean install -- which?
(d) At the About tab, does it say its version is
Version 2020 (Build 20.064.0329.0008)?
(3) Name a file/two whose permissions are suspect, & I'll compare them to mine. And say where they are & where you want to move them to (or whatever it is you want to do to them).
(4) I don't know iTunes. If it is only its files getting deleted, I'd say its an iTunes problem. Maybe there's an update.
(5) Glad to hear other favorite programs of yours are working in 1909. Yeah, settings would have to be reestablished after a clean install.
(6) "delete...or should they be reinstalled"
That decision is yours to make. But...
(a) Continue running Windows system image backup as before. Make a new one after major changes that were successful. I usually make a new one after a successful Quality Update (new OS Build). Rename each new image as
you make it, & delete the older ones when you feel it safe. I usually keep the last three. Remember, you can recover individual files off those images without restoring the entire image.
(b) Keep Autoruns & WUShowHide
for the next time they may prove useful. I have a shortcut to each of those on my Desktop.
(c) SetupDiag hopefully will no longer be necessary, can always be downloaded again, but maybe keep it till after 2004 has come in well.
(d) I don't know about Microsoft Silverlight, myself. I did install it once, not sure why it's gone now. Maybe it was my own clean install a few years ago.
