Remove C Drive network sharing

There are few methods available I suppose, and below are what I found;

1. Delete the sharing for the specific session only. Will re-share once reboot.
Start --> Run --> cmd
then type following command.
net share c$ delete

2. Permanently remove sharing.
Proceed to registry file by typing Start -> Run -> "registry". Look for below registry entry and amend accordingly.
Hive: HKEY_LOCAL_MACHINE
Key: SYSTEM\CurrentControlSet\Services\LanManServer\Parameters
Name: AutoShareServer for servers
Name: AutoShareWks for workstations
Type: REG_DWORD
Value: 0

Should you have any other methods, kindly post it and share~
