You want to share the entire C: drive instead of a single or multiple folders?
Anyway two things you need to do
First - Share the C:\ Folder. Go to C:\ properties, click the 'Sharing' Tab, Click 'Advanced sharing' select the 'Share this folder' checkbox, give the Share name. Click OK.

Second - On the 'Security' Tab under C:\ Properties, Click 'Advanced' button, under the 'Advanced Security Settings for Local Disk' under 'Permissions' Tab Click 'Change Permissions' Click 'Add' under Select users or group, type everyone (everyone is used to give Network users access to a folder in a non-domain environment) click OK, then select the permissions your want to give the 'everyone user' Click OK.

Optional step, check the 'Replace all child object permissions with inheritable permissions from this object' Click Apply or OK, you will be asked, Do you want bla bla, click Yes. It will take a long time depending on how large the drive is. This will ensure that you never get the access denied error message.

Then OK everything.

For sake of simplicity skip the optional step. But note that you will be able to access C:\ but may not be able to access the subfolders. No problem, just add everyone to the permissions list of the particular folders that give the Access Denied message. Its better this way.

Thats it.
