I'm running W10-64 (inside VirtualBox). Have done so for several months. Suddenly my machine exposes a strange behaviour that I have not seen before: after rebooting, the Mouse pointer changes into the "Wait State" and stays like that. I can start apps and use them without problems - the mouse pointer being the only problem, because pointing at things is not easy with the hourglass.

  • Looking through the list of recently installed apps, I see my company's app (harmless, installed before), Visual C++ 2015 Redistributables, Skype 7.5 and GitHub - nothing suspicious, I think.

  • After start, the CPU-Load goes to 100% but normalizes after everything has been loaded, and tasklist does not show anything using abnormal CPU%. CPU-Load while writing this msg in Chrome is around 20% (with 2 Cores).

  • Autoruns did not show anything that looked obviously wrong (no suspicious or unfamiliar names). However, I may have been tricked. But this setup took a long time of fiddling and has worked so nicely...until the mouse cursor disappeared. It would be great if this could be sorted out w/o having to uninstall everything - but even though I'm a developer, I'm not knowledgeable enough about the details of the Windows mechanics to fix this on my own...

P.S: following up on music2myear's suggestion, I tried to change the display of the mouse - it has no effect. I also visited https://www.w3schools.com/cssref/tryit.asp?filename=trycss_cursor just to see if the mouse would respond to CSS-Settings - it does not! (Apologies for posting a W3-Site ;-))

P.P.S: have also tried to disable all entries in Taskmanager's Autostart-Tab - no effect!

  • Have you tried changing the mouse pointer to a different style and then back?

  • Not yet! Just did it and selected a different cursor for the „Busy“-State, yet this had no immefiate effect when I closed the dialog. After restarting Windows, Busy-cursor still shown as hourglass, my new setting had no effect! When I go into the Mouse-Settings (2nd tab, „Pointer“), none of these choices matches the current cursor!

  • analyze cpu usage with WPRUI/WPA. here you see which process has the high cpu usage (Weight %) and when you expand the stack you see what the process does

  • I'll do that, but I don't think that CPU-Usage is the issue (down to 5% atm) - the immutable cursor seems to be the issue...

  • Ok, tried that - "Idle" gets by far the heighest Weight (86.4%) vs. CompbatTelRunner on place 2 with 3.3%.

Ok, first the good news: mouse pointer reset to Normal!

Bad news: I did not do anything to achieve this! That is certainly not true, I did many things, but none of that would explain the effect:

  • as mentioned in the P.S of the question, I had disabled all Autostart-Entries. Re-enabling them had no effect.

  • further googling gave me the idea to look for driver updates. So I went to Dell's website, logged in, downloaded the glorious "DellSystemDetectLauncher" which was supposed to detect my environment. Well, that download was just the installer - which attempted to download the software from the web. It could not do that, as I was told in an error-message. For more info, I was referred to a log-file in my TMP-Folder. This file had 0 bytes length!

  • a few reboots later cursor was reset. It's an unsatisfying end to the story, I wish I has an explanation - but I ended as it started: in totally misterious ways! :(
