windows 10 windows host process (rundll32)

[Bertybertbert]

HI! the rundll32 has been using 33% (average) cpu speed. It seems unusual, someone explain for me? THank you!!! It's been doing this for about an hour now, halp, thanks! This only occurred once I updated from Windows 10 1511 to 1607 (anniversary update).

Its a Windows system file that runs dll's as apps and could indicate anything from Windows performing maintenance to malware. See if it stops in its own. Try a deep system scan first in safe mode if youre concerned.
