Terms for using RDS CAL Store

The plain-language rules for buying RDS CALs from us: what you get, how delivery works, what happens if something goes wrong, and how we can help you.

Last updated: 28 September 2026
Your satisfaction matters to us Every order comes with 90 days of protection and installation help. If something goes wrong, we’re here to help put it right. If we can’t get your license working, you’ll receive a full refund. Refunds are issued within 24 hours.

1. Who we are and what you agree to

RDS CAL Store is a trading name of Sysvista Solutions, a company registered in England and Wales with its registered office at 399 High St, London E15 4QZ, United Kingdom. “We” and “us” mean Sysvista Solutions; “you” means the person or organisation using the website or placing an order.

By placing an order or creating an account you agree to these Terms, our Refund Policy and our Privacy Policy. If you are ordering for a client or employer, you confirm you are allowed to do so and to give us their licensee details.

2. What you are buying

We sell Microsoft Remote Desktop Services Client Access Licenses (RDS CALs) for Windows Server 2025, 2022, 2019 and 2016, as User CALs or Device CALs, in packs of 1, 5, 10, 20 and 50.

What a CAL is and isn’t

An RDS CAL licenses a user or a device to connect to Remote Desktop Services. It does not include a Windows Server license, hosting, hardware or server configuration. If you order the wrong CAL type, you can convert it for free through your account or with our help (section 6).

Downgrade rights

Newer CALs cover older servers: Windows Server 2025 CALs can license 2025, 2022, 2019 and 2016 RDS hosts. Older CALs cannot license newer servers.

Microsoft terms

Your use of the license is also subject to Microsoft’s product terms. Microsoft, Windows Server and Remote Desktop Services are trademarks of Microsoft Corporation. We are an independent license supplier, not Microsoft.

3. Ordering and payment

The price shown at checkout is the full price you pay us. Any tax that applies is included and shown before you confirm the order. Your bank or card provider may apply currency conversion or other fees, which we do not control.

Payments are processed by PayPal, including card payments made through PayPal checkout. We never see or store your card details.

4. Delivery and your account

Your license document, invoice, setup guide and installation video link are emailed within 15 minutes of checkout to the address you entered. A copy is saved to your account, which is created automatically if you don’t already have one.

If you can’t find your delivery email, check your spam folder or account, or simply contact us and we’ll help. Entered the wrong email or licensee details? Get in touch and we’ll help put things right.

You won’t be left to track down a missing order alone. We’ll help you access your license or re-send it. If we can’t complete delivery, you’ll receive a full refund.

5. Installation support

Help installing and activating your CALs in RD Licensing Manager is included with every order at no extra cost, including remote assistance if needed and with your permission. Reply to your delivery email or write to [email protected].

Support covers installing and activating the license you bought from us. Your protection is explained in our Refund Policy.

6. Guarantee, corrections and refunds

Every order is protected for 90 days from the date of purchase. If your license hasn’t arrived, won’t activate or doesn’t match what you ordered, we’ll help put it right. If we can’t, you’ll receive a full refund.

Trying to install or activate your license does not affect your protection if something goes wrong. If you ordered the wrong CAL type or Windows Server version, we’ll help convert your order. CAL-type conversion is free. For a higher-priced version, you only pay the difference, with your agreement.

Full details are in our Refund Policy. For the scope of the guarantee, order corrections and refund arrangements, that policy takes priority if these Terms differ.

7. What we ask of you

  • Check the Windows Server version and CAL type you need before ordering. If you’re unsure, our RDS CAL Advisor and support team can help you choose. If you discover a mistake afterwards, contact us and we’ll help you with it.
  • Please provide accurate billing, contact and licensee details, and keep access to the email address you used. If you notice an error, let us know so we can help correct it.
  • Keep your license details and account login secure, and use the license in line with Microsoft’s terms.
  • Don’t resell, share or publish license details except where Microsoft’s terms and the law allow.

8. Using the website

Please use the website as intended: no attempts to bypass checkout or security, no deliberately false information, no scraping, and no misuse of support channels. You are responsible for activity through your account; tell us promptly if you think it has been accessed without permission.

Site content, guides and branding belong to us or our licensors and may not be reused commercially without permission.

Chat assistant

Our automated chat can help with general questions. For advice about your order, email our team so a person can check the details and confirm the answer. Chat responses do not change these Terms or the Refund Policy. Please don’t enter passwords, card details or license keys in the chat.

Third-party services

We use third-party services for payments, email and videos. If a problem with one of these services affects your order, contact us and we’ll help. This does not reduce our delivery or refund commitments.

9. Legal terms

Your rights

Nothing in these Terms limits rights that the law says can’t be limited, including consumer rights where they apply.

What we’re responsible for

We are responsible for the license we supply and the commitments in our Refund Policy. We do not take responsibility for repairing unrelated problems in your servers, network, hosting or other software. That limit does not remove your refund protection for covered license or order problems.

To the extent the law allows, our total liability for an order is the amount you paid for it, and we aren’t liable for indirect losses such as lost profit, business interruption or data loss.

Events outside our control

Payment-provider or hosting outages and other events outside our reasonable control may cause delays. If your order is affected, contact us and we’ll help. These events do not remove your protection under our Refund Policy.

Governing law and changes

These Terms are governed by the law of England and Wales, except where mandatory consumer law in your country says otherwise. We may update these Terms; the version in force when you ordered applies to that order unless a change is required by law or is clearly in your favour.
