Accepted answer
Yes, that should be possible.

You'll first need to add a reference to your project to System.DirectoryServices.AccountManagement.dll and then use the following.code:

using System.DirectoryServices.AccountManagement;

// ...

PrincipalContext pc = new PrincipalContext(ContextType.Machine);
bool isValid = pc.ValidateCredentials(Environment.UserName, password);

if (!isValid)
{
// password is not correct for logged on user
}

To the best of my knowledge you can't retrieve your Windows system password directly because, for security reasons, it's held in hashed form and hashing is, of course, a type of one-way encryption.

There are (respectable) tools which can recover passwords but I think they work by trying a large number of combinations until they find one with the same hash as you typed in originally. This may not necessarily be the same as your original password because hashes are unlikely to be unique.
