Re: OT - Windows 10 - Fixing The Lag In Changing Virtual Desktops

2024-08-11 Thread Jacob Peck

Huh, interesting behavior you're seeing there.  I just played around with
the virtual desktops feature, then force-killed explorer (the 'root'
process), and then used File->New Task, typed 'explorer' in the box, and
hit enter.  It all came back no issue, other than closing the couple of
file explorer windows I had open.

Maybe I'm misunderstanding, but 'force kill explorer -> start a new
explorer task' has been my go-to Windows fix for most things for the last
20 years or so, and has worked without a hitch in every case for me (except
for a handful of times on Vista, but uh, Vista...). :)

Perhaps I've just been lucky?  Maybe the other 'explorer.exe' processes
running in your case were masking the issue -- IIRC, explorer does the
'root' check on startup -- if no other instances of explorer.exe are
running, it assumes complete control.  I can't remember the exact blog post
I read about this, but I think it was from Raymond Chen, who's been on the
Windows internals team forever.

But hey, you've got a fix that works for you, so at this point I'm just
nerd sniping myself.  Thanks for the puzzle and the tip! :)

Even if you can open a new instance of Windows Explorer, you have to open 
it in a special way for it to take over the desktop function.  Otherwise it 
will just show you the usual list of files.  The one time I managed to kill 
the root instance, I couldn't find a key combination that did anything.  I 
forget how I eventually shut down; it was too long ago.  I might have just 
held the power button down long enough.

I think this virtual desktops feature is one of Win 10's better ones.  In 
addition to -, you can move between adjacent desktops 
with  -  - , and this doesn't 
suffer from a lag.  Before this will work, you need to create another 
virtual desktop, which you can do with the  -  combo. On 
the display you will see a "+" sign labeled by "New Desktop".  That's how 
you create new ones.  I don't know if once created they can be removed.

Interesting find.IIRC the Ctrl+Alt+Del menu is part of the Kernel, and interrupts everything else happening on a Windows box.  If you manage to completely nuke Explorer, you should pretty much always be able to three-finger-salute into a Task Manager and go File->New Task and fire off a new ‘explorer.exe’ to un-bork yourself.  If the Task Manager is not working, then something is seriously wrong :)I break Windows quite often, but I don’t use virtual desktops.  I honestly didn’t even know Windows 10 had that feature :)JakeOn Aug 11, 2024, at 5:32 PM, Thomas Passin  wrote:This isn't about Leo but I can't be the only one affected by this problem, which can be very annoying.I use many virtual desktops in my daily computing.  Usually I have at least four, and sometimes up to six.  For example, my browser and email client are in one.  Leo and associated folders, command windows, etc., are in another, and so on.The problem is in switching from one to another.  - brings up a special view of all the desktops where you can choose one.  In this view you can also move an application from one desktop to another.  Over time, switching to this overview gets slower and slower until it becomes intolerable.  I've searched the internet without success.  The only cure I knew before today was to log off and log back in.Here's what turns out to be happening.

tl;dr - ChatGPT by and large did a pretty good job, but it's hard to

Here's a really good book covering the basics of neural nets, fuzzy logic,
and the relationship between them. It's rather old so it predates GPT and
modern systems with huge numbers of parameters, but it's really good (but
it has some math, because you can't escape that in this field). It's not
