 # Windows 365 User Logon Activity Script
 Currently Windows 365 does not have a way to report how often users are actually using their CloudPC. This example script aims to provide that information by querying the Azure AD Sign-In logs with the filter Application set to Windows Sign In, and then comparing this data against every user who has a provisioned Cloud PC. The script returns a count of every logon a user has completed against their Cloud PC, as well as their last logon time. The script **does not** return session duration.

 # Windows 365 and AVD Gateway IP Address Lookup Script
 ## Purpose
 This script helps to easily retrieve the AVD Gateway IPs or CIDR Subnets associated with the Windows 365 and AVD services and outputs them as a list in a CSV format. This list can then be used by admins to import the data into their VPN solutions to minimize end user Cloud PC performance degradation and disconnects.
