Why This Term is Different

Windows 10 stopped receiving security updates on 14 October 2025. For the first time, a laptop that ran perfectly well last year needs a licensing decision before it goes back to campus or the office. The 25% discount below applies to every Microsoft product Msckey sells, including the professional tools that are almost never discounted. Enter BTS25 at checkout; no minimum spend, no bundle required to unlock it.

Why buy from Msckey

We are not the cheapest software storefront online, and here is why that matters.

A license priced below what it costs to source legitimately has to recover that money somewhere. Usually it is the key that activates in September and stops working in March, with no reply from the seller when it does. Msckey prices sit where a genuine licence can be sold, supported and stood behind.

Stated licence type

Retail, OEM or Volume, and the number of devices covered, printed on the product page before you pay.

Delivery in minutes

Every product is digital. Keys and download links arrive by email. No shipping, no shipping cost, no waiting.

Written activation help

Step-by-step installation and activation guides, including phone activation, published on the Msckey blog.

Support that answers

A person replies at support@msckey.com — after the sale as well as before it.

Back to School Sale FAQ

The questions we get asked most during this sale.

How do I use the BTS25 coupon code?

Add any Microsoft product to your cart, then enter BTS25 in the discount field at checkout. The 25% reduction applies to your order total before payment. There is no minimum spend.

Which products does the discount cover?

Every Microsoft licence in the Msckey catalogue, including Windows, Office, Project, Visio, Visual Studio, SQL Server, Windows Server and Remote Desktop Services CALs.

When does the sale end?

The Back to School Sale runs until 31 August 2026. Prices return to normal after that date.

How quickly will I receive my licence key?

Keys are delivered by email, usually within minutes of payment clearing. Every product on Msckey is digital, so nothing is posted and there is no shipping charge.

Are these licences genuine?

Yes. Every licence is sourced through authorised channels, and each product page states the licence type — Retail, OEM or Volume — along with the activation method and how many devices it covers.

What is the difference between a Retail and an OEM key?

A Retail licence can be transferred to a different computer if you replace or rebuild your machine. An OEM licence is tied permanently to the first device it activates on, which is why it costs less.

What is a Multiple Activation Key, and who needs one?

A Multiple Activation Key activates many devices from a single key, so an IT team can deploy across a lab or office without entering a separate key on each machine. Msckey offers Windows 11 Pro MAK licences in tiers from 50 to 1,000 devices.

Do I need a new licence to move from Windows 11 Home to Pro?

You need a Pro upgrade key, not a full reinstall. The Upgrade From Windows 11 Home to Windows 11 Pro licence unlocks the Pro feature set on an existing Home installation, keeping your files, apps and settings in place.

Do I need to buy RDS CALs separately from Windows Server?

Yes. A Windows Server licence covers the server itself; Remote Desktop Services CALs license the users or devices connecting to it. User CALs suit staff who connect from several machines, and Device CALs suit shared machines used by several people.

Can I get a refund?

Refunds are available before your key is used. Once a key has been sent & activated, it cannot be refunded, because the licence has already been consumed. Full details are on the Shipping & Returns page.
