ok weird one ive followed every guide olnine: disabled SysMain, turned off Search indexing, even uninstalled some apps. still:

Disk 0 (C:) Active time 100%
Not responding
the family desktop is pegged after every boot. my patience is gone. is there a way to actually find out whats using teh disk instead of disabling random services? every guide says smth different and Im tired of guessing. if someone could show me how to find the real culprit, Ill happily do the work.
