Was the TempDB data file on that drive? A restart of SQL Server will rebuild the temp database so could have released space that way. Could also be an ldf file on that drive which committed the transactions to an mdf file on another drive.
Here tempdb could be reason from which system relcaimed the space.but NOT any ldf file as log file never release(shrink) space, it basically make the space reusable.
