(1) File name:
{ca0a01b4-d58c-11db-8afb-0013720efba8}{3808876b-c176-4e48-b7ae-04046e6cc752}.

(2) Partition is NOT System partition.

(3) System Restore on this partition was ENabled by default, but is now
DISabled.

(4) File is modified after each boot. (System log entry nearest to
Date/Time Modified is Windows Modules Installer service entering stopped
state.)

A single file consuming over 25% of a partition seems excessive. Any
ideas?

TIA.
