WDFME.exe RAM hog

WDFME CPU hog for me 98-99% the last few days even when my passport drive is not plugged in. Running XP pro sp3. All was well when originally installed last weekend - but this weekend PC is unuseable. Can kill the process and appreciate those on here who have work arounds but fact is this then means you are doing manual back ups - not automated. It just doesn’t do what it says on the tin and a fix is needed from WD asap
