Hi there,


This morning my girlfriend woke up and loaded up her PC after an Automatic Windows update last night. She noticed that it was extremely slow and almost unresponsive in some cases.


Upon checking the task manager we noticed 100% Disk usage on the Performance Monitor. We've tried a few things suggested in some Windows support threads but nothing seems to be working so far.


Solutions tried so far:


- Disabling Prefetch Resources in Chrome and Allowed Write permissions on Skype (Apparently there was an issue with these clashing?)

- Setting the system Page File manually, this didn't work on manual setting or Automatic.


It's been suggested in some Microsoft support threads that Win10 is too much for older systems and hard drives, any truth in this?



Any help would be greatly appreciated as she currently can't use her computer for work or gaming.



EDIT:  We've noticed now that after a short time the Disk usage drops to around 60% and then slowly raises back to 100% again.

EDIT2: We attempted to troubleshoot any startup programs so went to the task manager to turn everything off for a startup (msconfig doesnt work on win10 it seems), and suddenly her Disk usage dropped back to 0-3%. Honestly don't know whats going on. Didn't think disabling startup programs would change anything until a restart heh.

EDIT3: Went back to 100% Disk usage after about 4-5mins of 0-3%.

 It could be an antivirus scan.  I know Defender will do that after booting.  In Task Manager click the Processes tab, then click twice on the Disk column header.  That will sort the processes in order of which task is doing the most disk activity.


 Good luck.

Make regular full system backups or you'll be sorry sooner or later.
