Was recently invited to update from Windows 7 to Windows 10 and accepted. I seem to be on the bleeding edge because help files for my problems haven’t appeared on the web yet. As for help files on my computer – they vanished many years ago.
The update process to Windows 10 was surprisingly painless. I needed to respecify my preference for a few default options (such as Chrome rather than Edge for browser).
The main annoyances so far are the things that have been deleted by the system in going to Windows 10.
1) I can no longer log off or switch users in Windows 10 – unless I “ctrl alt del”. Yuk.
2) A bug I had in Windows 7 becomes much worse in Windows 10. Before, from the logon screen I had to click “switch user” and type my username. The “switch user” has vanished from Windows 10. Now it automatically logs me in under the wrong username then I have to “ctrl alt del” to get back to the login screen.
3) The new “scientific” calculator in Windows 10 doesn’t have an “inv” button so now I can’t do arcsin or arcsinh. That’s no use.
4) The game minesweeper has been deleted from my machine. And no – a copy on the web is not a substitute.
5) There’s also a popup window that activates on every login warning me about starting the window manager twice, that I have to manually kill. I’m sure they’ll have a patch for that soon if not already.
6) Annoyances from Windows 7 haven’t been fixed – such as displaying all desktop icons on login and then deleting all desktop icons before slowly reprinting them. That bug should have been fixed by now.
