Well... I'm officially on "the other side" now. My W11 PC (a Lenovo Thinkpad P16v Gen 3) arrived this morning and I've spent all day making it usable. That may sound sinister, but it really could have been a whole lot worse.
The machine itself is certainly decent - solid, business like, quiet. Lovely OLED screen, though for some reason, fonts all look a little thin, which isn't terribly attractive or readable but I'm sure there's a setting somewhere for that.
Of course, first power up means going through the first time setup wizard. I have an MS account already, so the easy thing to do is use that for the built in account, then add a local admin account later. This option still exists but is confusingly labelled and hard to find. (Settings - Accounts - Other Users - "I don't have this person's sign-in information" - "Add a user without a Microsoft account", then add a user name). Once the user is created, you can make them admin, and delete the original MS account, leaving a local user account as the only one on the system.
Nudges, and dark patterns in UI design? F**k them sideways.
Fortunately that was the only really offensive part of the process. I expected to have to turn off a bunch of frivolous sign-in options, and recommendations for back-up and other features that conflict with privacy... no worse than W10 in that regard. I also uninstalled some things I know I won't be using: 365, Excel etc, and stopped a bunch of things like OneDrive and Edge from loading at start-up.
Goodbye also to Lenovo's "digital wellness" application, though I left "commercial Vantage" alone for now.
The first and only real hiccup was installing OrCAD. The HASP (dongle) driver didn't work, but I was fairly easily able to find an update from Thales, who apparently now own that particular IP. With the new driver installed, the OrCAD installation took ages (as it always has done), but succeeded. Repeat the exercise to install the most up-to-date hotfix - also takes ages - then try and figure out how to make the UI look like the one I've clearly quite heavily customised over the last 5 years or so.
I can't blame W11 for that being a cumbersome task; looking you squarely in the eyes here Cadence. But it's done now, and the new machine is waaaaaay faster at rendering than my old £600 HP with integrated graphics. I'm actually looking forward to my next PCB.
Other installs? Thunderbird, Crossworks, Firefox, Libreoffice, Code::blocks, ST utility / CubeMX, various other bits & pieces all installed OK. Network drives all mapped to my NAS. File explorer opens directly to "This PC" and isn't nearly as slow as I'd been led to believe. I'm also curious to see how LTSpice behaves on a Core Ultra 9 285H vs my 6 yr old i5.
So far, so good, then. There was one nasty graphical glitch the first time I ran PCB Designer, but I've not seen it since so hoping it won't recur. Otherwise, tomorrow is a normal working day and I'm cautiously optimistic that it will indeed be an ordinary one - just with a faster PC.
