These are both GUIDs for comports. They have something like this under them:

Code:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceClasses\{86e0d1e0-8089-11d0-9ce4-08003e301f73}]

[..\##?#ACPI#PNP0501#1#{86e0d1e0-8089-11d0-9ce4-08003e301f73}]
"DeviceInstance"="ACPI\\PNP0501\\1"

[..\##?#ACPI#PNP0501#1#{86e0d1e0-8089-11d0-9ce4-08003e301f73}\#]
"SymbolicLink"="\\\\?\\ACPI#PNP0501#1#{86e0d1e0-8089-11d0-9ce4-08003e301f73}"

[..\##?#ACPI#PNP0501#1#{86e0d1e0-8089-11d0-9ce4-08003e301f73}\#\Control]
"Linked"=dword:00000001

[..\##?#ACPI#PNP0501#1#{86e0d1e0-8089-11d0-9ce4-08003e301f73}\Control]
"ReferenceCount"=dword:00000001



Same for the other GUID. Dunno if it will help or not. None of these link to the COM? names. So it might try to open the strange device names...
