Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello Magic,
Glad to help you here.
If you already have Microsoft 365 Business email account, as far as I know we could directly purchase windows 365 cloud pc license from Microsoft 365 Admin Center > Billing > purchase services. It requires you have billing admin or global admin rights to purchase windows 365 cloud pc license. Moreover, windows 365 cloud pc is user-based license product, this means every user who need windows 365 cloud pc must be assigned valid cloud pc license, so you would need purchase four cloud pc licenses for your users, and the single cloud pc cannot be shared with multiple users, thanks. For your reference https://www.microsoft.com/en-us/windows-365/faq >> Windows 365 allows one user per license and doesn't support multiple users on a single Cloud PC.
Please feel free to let me know if you need any further help, thanks.
Best Regards,
Oliver
