@ mpackThank you for the quick reply.
You have quad core CPU and have assigned all four cores to the guest. Not good. In your case I'd assign a max of 2 cores.
I changed settings to make it 2 cores. Thanks for the advice.
An error like this is usually a bad device driver. Look for drivers in the guest that are not native to Windows or VirtualBox. Since you suspect that browsing the guest filesystem is involved then I'd look first at any unusual filesystem layers, e.g. Bluetooth.
Bluetooth is not installed on this VM. All drivers on this VM are listed as follows:

rsdrvx64.sys is IDed at SystemLookup as legitimate.
http://www.systemlookup.com/search.php?list=&type=filename&search=rsdrvx64.sys&s= Quoting, "Related to dddskx64.sys RawDisk Driver. Allows write access to files and raw disk sectors for user mode applications in Windows 2000, XP, 2003, Vista, 2008. from EldoS Corporation." I know I didn't install
ElRawDisk intentionally. Is it required for Vbox? Is it safe to remove it?
idsvc is a component of Windows CardSpace.
http://servicedefaults.com/7/idsvc/ It is legit and it is not running.
wpcsvc is a component of Parental Controls.

I noticed the
All Aboard keyboard manager on this VM as follows:
- Code: Select all Expand viewCollapse view
C:\Users\VM10\AppData\Roaming\Mozilla\Firefox\Profiles\hv1gcpce.default\Extensions\@all-aboard-v1
I know I didn't install it intentionally. Is this a required part of Vbox? Although it may not contribute to the current problem, I'd like to know whether it is safe to remove it.
@ Clipper87I have deferred upgrade to Anniversary edition for two months. This VM is still running Win10 Version 1511 (X64).
The only change I've made so far is to change from 4 cores to 2. I'll post back again after running for a while to see if the "memory could not be read" error returns.
Thanks again for your help.
