This has happened twice now in three months:
After rebooting, ALL the pinned items from my Windows Explorer taskbar jumplist are gone. Also, recent items from Windows Explorer are much fewer, only one or two if I remember correctly. After the first time I re-pinned the items I wanted, but about a month later it happened again. I re-pinned
All other pinned items in other jumplists (e.g. Word) are fine and have never disappeared.
Googling for the problem showed that ccleaner can affect this, but I personally do NOT use any cleaners or related progs on this machine.
I also think that both times it happened it was after a windows update, although I can't recall what kind of update it was.
After each time, Little Registry Editor showed invalid references in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\RecentDocs , but I had NOT used it prior to the deletions.
Any ideas on why this happens and how to prevent it?

I have this happen all of the time, but perhaps Windows removes these during routine "Computer Maintenance".
Try disabling "Computer Maintenance" in
Control Panel > System and Security > Troubleshoot common computer problems* > Change settings [left pane]. (Set "Computer Maintenance" to Off.)* - Words may have changed. Could also read "Find and fix problems", etc.
I took these instructions from "Method 2" in Microsoft KB978980, but posted them here since I could see Microsoft removing these instructions if too many people realize "Computer Maintenance" causes problems.
