I've been through many migrations and have installed BOINC on the data drive in portable format w/ no dependencies on the Windows registry.
The machine name will not change.
This is my main machine and the OS and data folders have been steadily migrated since 1998 with apps from Windows 98 that still will function as the needed libraries are still available (although I use none of those now)
This laptop's LCD lamps dying and the screen's gone dark at the right side. I put on an external monitor. The other laptop's down to one cooling fan.
These machines need to be replaced.
I'll put it off as long as possible but I can not wait another year.
