Sorry this ain't a proposed solution, chipping it (contesting the above) as I'm having it on windows 7 (64-bit??)
I use differencing-disks to manage my virtual volumes, and have noticed this bug. It's a bona-fide mystery -
I thought I'd found a fix. During a test, booting into a FRESH build (not a single driver install or reg tweak), I created a new user account (on one of many builds exhibiting the bug). Not affected, I assumed it was an HKCU issue, began rolling back... discovered the bug APPEARED fixed**, and made a point to try this 'create new user profile' weird fix (that fixes the affected, main user profile).
It didn't. New user account on another build also exhibits full.{name}, and re the fixed ^ account (that I'm considering making my new base, JUST so I don't have this annoyance...) still exhibits some symptoms of sickness (it's completely erratic, from what I've observed).
After a rollback, the symptoms aren't exhibited... but I'd rather not roll all the way back, just for tis (plus what if it reoccurs? ie not ideal 'solution' - rollback-workaround)
I'd love to try a competent, advanced, maybe-multi reg-hive comparison... but don't know how to do this @ like-system(s) level, without getting a
W&P-style report...
Thoughts?
