Windows 10: 100% DISK usage causing slow system startup

I've discovered that once you can bring up task manager, go to the performance tab and open resource monitor (link at bottom). Then go to disk tab and in the lower window click on total and sort from largest to least. You can see exactly which processes are using the most disk.

 

I've watched my development machine in a VM, and it appears to be windows defender cache files.

 

already done that, see my very first post.

 

So, I wil be grateful if you told me how whose possible to start it in safe mode, cause I could't .....I use all "F" keys but whoesn't possible to iniciate in safe mode ( I whose interested to start it in safe mode with network); not even task manager I wasn't able to start it, not even "cmd" command. I look like frozen system .....I whose try to scan it with antivirus live cd based on Linux, but don't let me connect to internet either to scan it. Is a kind of urgent, thanks !

 

Culprit is windows defender, to disable it use this application.

In 8 or 8.1 and 10, you no longer need to defrag. Windows runs a process that automatically defrags your drive in the background. WHich is why anytime you open disk management and click analyze it says you do not need one I forget which process it is...

 

*Smile, listen, perhaps you don't undestand me. The computer is totaly frozen, so it's impossible to instal/remove something, even shutdown sometime doesn't work, meaning fisical shutdown button.

 

So, the problem I whose solved myself. How ? By formating with Parted Magic the "C" in GPT (again), because the windows 10 installer said me that there is an GPT partition than allready exist and is impossible to install in it, except if I change the GPT type to MBR *Cool ! So, That's what I was doing, partitioning "C" to NTFS, the WIndows 10 detected it and formating to GPT again (with data lost, of course) and the computer work's now. Thank's, it seems that the student give lesson to the profesor .....
