Specifications Microsoft Does Not Publish for This Product

The following are commonly asked about but are not stated on any current official Microsoft source for this part number, so SourceIT does not quote them: component names, which component the AES claim applies to, operating-system list, wireless range, battery type and count, mouse tracking technology, resolution in DPI, button count, keyboard layout, dimensions, weight, colour and a manufacturer warranty term. We would rather leave a field blank than print a figure we cannot substantiate.

Microsoft has withdrawn its own-brand PC accessory catalogue. The microsoft.com/accessories product pages for this range now redirect to Microsoft's general hardware-warranty and PC-accessories support pages, and the Microsoft Store Singapore PC-accessories collection returns no results. Microsoft has published no formal discontinuation notice for this product; the evidence is the removal of the pages themselves.

A routed Microsoft Store listing for this set survives in one market and shows the product as out of stock at Microsoft. The equivalent United States address for the same listing returns a not-found error, so the surviving page is market-specific. Microsoft has published no end-of-support date.

This set is not named in Microsoft’s current Mouse and Keyboard Center supported-device list, although a Wireless Keyboard 850 is listed as an individual component. Treat set-level software support as unconfirmed.

Microsoft publishes the AES 128-bit encryption claim as a set-level feature without naming the component. On Microsoft’s page for the Wireless Desktop 900 the equivalent claim is explicitly attributed to the keyboard; here it is not, so we do not attribute it either.

This listing shows zero inventory in our system. Contact SourceIT for the current stock position and lead time before you raise a purchase order.

Warranty Position

Microsoft no longer publishes a warranty term for this product. Microsoft's current PC accessory warranty page states only that the accessory "comes with a 'limited hardware warranty' depending on the device" and directs the buyer to check their proof of purchase to identify the warranty period. SourceIT therefore does not quote a manufacturer term for this item. Ask our team to confirm the warranty position in writing before you order.

The local warranty named in the heading of this listing is SourceIT's own commercial term, not a figure published by Microsoft. Ask our team to confirm the term in writing with your quotation.

Microsoft publishes no operating-system list for this set on any current page, so we state none. The only compatibility statement Microsoft still makes is that it works with all Surface models that have a USB-A port.

Setup is a plug-and-play transceiver in a USB port. Microsoft does not publish the wireless range or the radio frequency for this set.

The set is not named in the current Microsoft Mouse and Keyboard Center supported-device list; the Wireless Keyboard 850 appears there as an individual component, which is not the same as set-level support.

Only the Microsoft sources above were used to build this page.

Is the wireless link encrypted?

Yes. Microsoft publishes Advanced Encryption Standard (AES) 128-bit encryption as a feature of this set. Microsoft does not state which component it applies to, so we do not attribute it to the keyboard or the mouse specifically.

How long does the battery last?

Microsoft publishes a two-year average battery life. It does not publish the battery type or how many cells each device takes.

Are the keys quiet?

Microsoft publishes quiet-touch keys for this keyboard, which is the reason it is often chosen for open-plan and shared-desk environments.

Does it use Bluetooth?

No. Microsoft describes an easy, reliable plug-and-play transceiver, so it occupies a USB port.

What operating systems does it support?

Microsoft publishes no operating-system list for this set. The only compatibility statement it still makes is Surface models with a USB-A port. Ask us if you need this confirmed for a specific platform.

Is the mouse full-size?

Yes, Microsoft publishes it as a full-size mouse rather than a compact travel model.

What warranty applies?

Microsoft publishes no warranty term for this set. Its current PC accessory warranty page directs buyers to their proof of purchase. SourceIT supplies it with local support and a GST invoice. The local warranty named in the heading of this listing is SourceIT's own commercial term, not a figure published by Microsoft. Ask our team to confirm the term in writing with your quotation.
