'ZDNET Recommends': What exactly does it mean?
ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.
When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNET nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.
ZDNET's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services.

Can I install Windows 11 on my PC even if Microsoft says it's 'incompatible'? [Ask ZDNet]
Welcome to another installment of Ask ZDNet, where we answer your technology questions.
In the mailbag this week: Can I install Windows 11 on my not-very-old Surface PC even if Microsoft says it's incompatible? And why can't I say no to driver updates from Windows?
If you've got a question about any of the topics ZDNet covers, one of our team of editors and contributors probably has an answer. If they don't, we'll find an outside expert who can steer you in the right direction.
Questions can cover just about any topic that's remotely related to work and technology, including PCs and Macs, mobile devices, security and privacy, social media, home office gear, consumer electronics, business etiquette, financial advice... well, you get the idea.

How can I install Windows 11 on my "incompatible" PC?
I have a perfectly good Surface Pro 5 PC with an Intel Core i7-7660U CPU, running Windows 10. It's only a few years old. When I check Windows Update, I see a message that says it's not compatible with Windows 11. Will this machine eventually support Windows 11? Is there any way around this?
Microsoft officially released the Surface Pro 5 in June 2017 and continued selling it as a current model until its successor was released in October 2018. That means your Surface Pro is probably about four years old and should have plenty of useful life remaining. Alas, its 7th Generation Intel Core CPU isn't on the list of Windows 11 compatible CPUs, which means upgrades via Windows Update are not supported and probably never will be.
There are, however, two workarounds, as I document in ZDNet's Windows 11 FAQ.
If you're willing to perform a clean install of Windows 11, you can boot from installation media and run Windows Setup. That option skips the CPU compatibility check completely.
To upgrade your system, you need to modify the registry, as documented in this Microsoft support document. (The usual warnings apply when working with the registry. Make a complete backup before proceeding.) Open Registry Editor and navigate to the following key:
HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup
Create a new DWORD value, AllowUpgradesWithUnsupportedTPMOrCPU, and set it to 1.
You can now perform the upgrade by downloading an ISO file, mounting it as a virtual drive, and running Setup from Windows 10. You'll see a stern warning about compatibility issues, but after you click OK on that dialog box your upgrade should proceed without any serious issues.
Why am I getting new drivers through Windows Update?
When I checked for new updates at Windows Update, one of the updates was a new driver for my fancy gaming mouse. I always thought driver updates were optional, but this one doesn't give me a choice. I have to install it along with all the updates for Windows. What's happening?
Some driver updates are indeed optional, but if you're offered a driver through Windows Update without the option to refuse it, the developer of the driver is the one who made that decision. When the developer submitted that driver to Microsoft, they checked the box that reads Automatic, which means they wanted it delivered to all applicable systems. And before the driver made it to Microsoft's update servers, it also had to go through formal "flighting tests" with PCs in the Windows Insider Program.
(If you're curious about Microsoft's rules for driver developers, see the article "Understanding Windows Update rules for driver distribution" at the Partner Center for Windows Hardware.)
Typically, drivers delivered in this fashion fix hardware issues that have been identified (using telemetry data) as causing problems for a significant group of customers. Delivering those fixes through Windows Update is a much more reliable way of resolving those issues than depending on customers to download and update drivers manually.
In the rare case that a driver delivered as an automatic update causes problems, you can and should take it up with the manufacturer of that hardware.
