_windows.pyd is a process file that belongs to the Python programming language.  Python is a popular language used in a variety of applications.

_windows.pyd has been associated with Bittornado software.  It may or may not appear with other software as well.

Process files-those with .pyd, .dll, and certain other designations-run in the Windows registry.  The registry is a database of all processes on a computer.  It runs them in batches and directs them to the right target so that they don’t waste time and processor speed finding the correct applications.

Through no fault of the user, registries often become cluttered or corrupted.  This can be because of programs that didn’t uninstall properly or because of out-of date files.  Some files may also be damaged by viruses or other malicious software; these files are rarely healed by anti-virus software.
