This value is called SID. SID is a unique user identifier. This is so windows still knows who you are even if you change your username. :)

To get the SID of the currently logged user you could try:

string username = String.Format(@"{0}\{1}", Environment.UserDomainName, Environment.UserName);
System.Security.Principal.WindowsIdentity id = new System.Security.Principal.WindowsIdentity(username);
string sid = id.User.AccountDomainSid.ToString();

or:

System.Security.Principal.WindowsIdentity id = System.Security.Principal.WindowsIdentity.GetCurrent();
string sid = id.User.AccountDomainSid.ToString();

I hope this helps. :)

Solution 1

There are no commands for searching the registry that I know of. Why does the value you need change ?

Solution 3

Instead of using a hardcoded SID, why don't you use the Registry.CurrentUser[^] field to access the subkeys? This would provide a portable solution, which is what I assume you're going for.
