Frequently asked questions
Check our detailed FAQ page.
What do I get with my purchase and how fast do I get it?
Your email arrives within 15 minutes of completing checkout and contains — a license document (PDF), setup guidance, a video installation guide, and invoice.
Is the Windows Server operating system included?
No. An RDS CAL is an access license for Remote Desktop Services and does not include the Windows Server 2019 operating system itself. The Windows Server 2019 needs to be licensed separately.
Will these RDS CALs expire or require renewal?
No. These are perpetual RDS CALs and do not require monthly or annual renewal. Once purchased, the licenses remain valid for the supported lifetime of the Windows Server RDS version they are purchased for, including eligible downgrade use.
What are my options if I ordered the wrong Windows Server version or CAL type?
If you ordered the wrong CAL type, converting between User and Device CALs is free. You can make the change through your account or contact us for help.
If you ordered the wrong Windows Server version, contact us and we’ll help convert your order to the correct version. If it costs more, you’ll only pay the price difference.
What if there is a problem with my order?
Every order is covered by a 90-day money-back guarantee. If we can’t resolve an issue with your RDS CALs, you get a full refund. Refund policy →
Is technical support included?
Yes. Every order includes technical support at no extra cost. Our team can help with installation, activation, and errors or licensing issues affecting your RDS CALs.
How are these RDS CALs installed?
RDS CALs are installed online through Remote Desktop Licensing Manager on your Windows Server.
Can I use these RDS CALs in my country?
Yes. RDS CALs are not region-locked — they can be deployed on Windows Servers located anywhere in the world, whether on-premises or on dedicated cloud servers.
Can I use these RDS CALs alongside my existing RDS CALs?
Yes. You can install additional RDS CALs on your existing RD Licensing Server alongside your current licenses.
Can I reuse my RDS CALs after a server reinstall or migration?
Yes. Your RDS CALs can be reactivated after a reinstall and transferred to a new server when you replace your hardware. Just make sure the licenses are only active on one server at a time — once the old server is retired, activate them on the new one.
