Well, mervynnunley, that has to be my favorite solution (!), but so far it's not happening!
I don't know if this is any helpful information, but I have also had this error message come up, usually too fleeting to read, but it stayed once long enough to copy:
svchost.exe - Application Error
The exception unknown software exception (()xc000000d) occurred in the application at
location 0x00007FB399FB399EB290
Click OK to terminate the program.
I dont' know how to determine what that is.
I bought the laptop in late 2013. I have a recovery thumbdrive from June 2015. That may have been after the upgrade to Windows 10 but not sure. I am not sure how to use it in my present circumstances. Also, do I have the option to recover preserving
programs and data, or does this operation wipe everything out?
