[Resolved] Windows 10 running EXTREMELY slow

[Sarthak]

Windows 10 is running unbelievably slow, without even runnning any applications. The cursor even lags when i move the mouse. I've checked online and I'm not sure what's going on. I had bootcamp earlier running windows 10 on the same laptop (2017 MacBook Pro) and it had the same issues.

I had bootcamp earlier running windows 10 on the same laptop (2017 MacBook Pro) and it had the same issues.

Can you explain that part? You were really dual-booting your Mac, and when booting in the Win10 option, you were seeing slow responses?

00:00:01.500171 NumCPUs <integer> = 0x0000000000000002 (2)
00:00:01.716437 CPUM: Physical host cores: 2

You have assigned all your CPUs to the VM. The host is going to run low on resources, since VirtualBox cares about physical processors (cores), not logical ones (threads). Your i5-7267U has 2 cores / 4 threads...

You haven't even installed Win10. You're booting from the DVD. Install it, then install the Guest Additions (ch. 4.2 of the User Manual), then we talk again...

Unless your startup sequence is asking you to "Press any key to boot from the DVD" and you don't. In which case you should 1) eject the DVD, 2) install the Guest Additions (ch. 4.2 of the User Manual), 3) we talk again...

BTW, the proper way to capture a log is:

• Start the VM from cold-boot (not from a paused or saved state) / Observe error / Shutdown the VM (force close it if you have to).
• With the VM completely shut down (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".
• Save only the first "VBox.log", ZIP it and attach it to your response. See the "Upload attachment" tab below the reply form.

Installing guest additions alone fixed all the issues I was having. Reduced it to 1 core after that just to be safe.

Great, thanks for the feedback. Marking as [Resolved].
Moving to "Windows Guests" from "OSX Hosts".
