To find your Microsoft Office product key, start with your purchase records and the account linked to Office.

Windows Hello lets you sign in to your Windows PC with a PIN, facial recognition, or a fingerprint instead of typing your account password. The important difference is that your Windows Hello PIN belongs to that particular device. It is not a shorter version of your Microsoft account password.

To set up Windows Hello in Windows 11, open Settings > Accounts > Sign-in options and choose your preferred method. A PIN works without biometric hardware. Face sign-in requires a compatible infrared camera, while fingerprint sign-in requires a supported reader. This guide walks you through setup, explains the security basics, and helps you fix common sign-in problems.

fClientDisableUDP - Disable UDP for RDP and Force TCP in Windows Header

Remote Desktop sessions that freeze, pause, or disconnect can sometimes be stabilized by disabling UDP on the Windows client. The policy value fClientDisableUDP provides a direct way to do this. Set the DWORD value to 1, reconnect, and Windows will use TCP only for new RDP connections.

This setting is useful when a VPN, firewall, network appliance, or unstable connection does not handle RDP over UDP reliably. However, it is a troubleshooting measure rather than a universal fix. UDP can provide a smoother Remote Desktop experience on healthy networks, so you should only force TCP when testing or resolving a specific connection problem.
