Windows 10: how to change ownership of c drive to everyone?

Is there a way to change ownership of the C drive to everyone?
I tried right clicking, Security -> Add -> Everyone (check name showed ok), then set it to full control, and hit apply, but when I open a command prompt and type echo # > bla, it still fails??
I can see its going to be hard being a developer on windows 10

What are these files 1bccc6a55feb06465f27253b879caa54_f820ab25-4d51-4e20-97d5-18f9cfca120f

These files are, in fact, owned by TrustedInstaller. I can change the ownership one file at a time but there are 490 of them. They are located in the C:\ root directory so I can't change the ownership of drive C because it wants to change every file
in the drive. Is there any way to change the ownership of these files as a group?

 

Restore ownership of the C Drive in Windows 10

Since upgrading to Windows 10 I experienced numerous problems with my external drive backups (Syncback Free). As a result I started changing the ownership of files so I could perform the desired backups. I inadvertently changed the C drive and now it
takes 2 1/2 hours for my laptop to start or restart. In addition, my Outlook pst files are gone and I have lost all client emails and calendar data. I have done multiple system restores and it doesn't help, the ownership of the C drive is still me. How
do I restore ownership to a default or change ownership back to what Windows wants to see?

 

You do not want to change the ownership of the whole C: drive. Many files are system files which are locked and or Hidden. These files are set to System as the owner. These files are locked or hidden for a reason. They don't want you to mess with them. Changing permissions on System Files may make Windows unbootable.

 

So, how else do I get the ability to echo # > bla in the command prompt from the root of c?
I have hundreds of tools which all make dirs/files in the root of C, and I really don't feel like changing them all just because a new version of windows came out.

 

I'm confused, why the need for permissions change in order to allow "...hundreds of tools [to] make dirs/files in the root of C..."? Very few of my programs need any help from me to install their stuff off of C-root. Are you wanting to force programs away from Program Files and Program Files (x86) and onto C:\[root]? And, have you been already forcing program installs away from PF and PF86 and onto C:\[root]?
