Back in the days, the net send command-line tool used to be quite popular among systems administrators and let’s be fair, it used to run smoothly and fulfilled a purpose. Though, I have seen many instances where it was used to prank users with fake messages like ‘hi, the system has detected that you have a low IQ. Please consider upgrading for better performance’. Since Vista, Microsoft introduced the message (msg.exe) command-line tool instead, which like the net send worked like a charm. However, in Windows 7 the MSG command may fail to send a message and returns an ‘Error 5’ message.
Most third-party applications pick registration details from the system and such details were inputted during the installation of Windows 7. The owner name and organization details stored in Windows can be displayed using the winver.exe application but cannot be modified through the GUI.

Say, you have bought a used computer or exchanged your computer with a co-worker and there’s no need to re-install the whole thing from scratch! You can directly change these details from the registry editor.

A memory dump during a crash of Windows 7 will fail if your system drive (%SystemRoot%) has less than 25GB of free space! Memory dumps help you diagnose crash issues and it is always recommended to allow enough free space on your system drive for debugging information to be logged and for better overall performance. You can set the dump file to be stored on a different local drive with ample storage space or disable this feature, but in cases where this is not possible and regardless of free space, you can force Windows 7 to create a dump file using the following new registry entry:
The default Windows shell in Windows 7 is the Windows Explorer, however you can replace it with other shells such as, the command prompt, Windows PowerShell or custom built shells. This may become handy when computers are running specific tasks and you want to restrict their usage or free up resources taken by the default shell. However, remember that if for example you set the command prompt as the default shell, users can still load the default shell and other hidden applications.
