Users are finally switching over to Windows 11 — mainly because the cost of staying on Windows 10 is set to soar

Windows 10 likely to lose users every October as ESU costs rise Three years of Windows 10 ESUs costs $427 per device Windows 7 took a big hit after the third year ended The latest tracking figures from Statcounter have revealed Windows 11's market share continues to grow as more and more users make

Prices will again double for the third and final year, too, bringing the total three-year cost to $427. That's $42,700 for a tiny fleet of just 10 PCs.</p><p>So while last year's extension was largely seen as buying time for companies that hadn't yet switched, it's now becoming too expensive for many to justify staying on Windows 10</p><p>But the story isn't as simple as companies not wanting to upgrade to Windows 11 – in many cases, specialist hardware or older, unsupported devices are imposing a technical block to the upgrade. </p><p>In the long run, it will likely mean that Windows 10 market share won't take a sudden drop, because most of the remaining devices will likely have a very valid reason not to be moved to Windows 11.</p><p>But we've seen it all before – Windows 7 lost support in 2020 when it still accounted for a quarter (24.9%) of installs – by the end of the third year of ESU, it had just a 9.6% share, but just two months after, it had fallen to 3.7%. So if Windows 7 is anything to go by, we can expect Windows 10 to stick around for a considerable number of devices until at least October 2028.</p><figure class="van-image-figure pull-right inline-layout" data-bordeaux-image-check ><div class='image-full-width-wrapper'><div class='image-widthsetter' style="max-width:676px;"><p class="vanilla-image-block" style="padding-top:31.51%;"><img id="diM9tpwF2Lz85R8q85CT78" name="tr-g_news" alt="Google logo on a black background next to text reading 'Click to follow TechRadar'" src="https://cdn.mos.cms.futurecdn.net/diM9tpwF2Lz85R8q85CT78-1920-80.jpg" mos="" align="right" fullscreen="" width="676" height="213" attribution="" endorsement="" class="pull-rightinline"></p></div></div></figure> </article> ]]>
