The security patches that Microsoft rolled out in October to fix critical vulnerabilities in Windows 10 have been in place for over a year, and many users have been waiting for them to roll out to their computers.

Now, however, Microsoft has revealed that they’re not rolling out the patches to all PCs, and that some of them are only being distributed to customers who bought a new machine that is running Windows 10.

The company says that they only distribute the patches that are required by the current hardware, and only to those who have the necessary hardware to install the security updates.

So, for example, if you buy a new laptop that’s running Windows 7, you’re not required to install any updates.

That’s a little surprising given the company’s previous statement that only those who bought the new machines that are running Windows 8.1, 8.2, 8, or 8.3 will be required to update their PCs.

So while the new patch is expected to be deployed to all of the machines that have the hardware required for the upgrade, some of the patches may not be available to those users.

This means that those users will have to download the updates from Microsoft’s website, and then wait for the patches in order to upgrade to the new hardware.

“We only distribute updates to those customers who are in compliance with Microsoft’s software update policy,” a Microsoft spokesperson told TechRadar.

“If you have been told otherwise, you should check your hardware or firmware version.”

The company notes that this applies to both older and newer machines, and says that customers who have not installed the updates on their machines “should check their hardware for the correct version of Windows”.

Microsoft has released a patch for the vulnerability that was discovered on Thursday, which fixes the issue for users running Windows XP, Windows Server 2003, Windows Vista, Windows 7 and Windows 8, and for Windows XP Professional, Windows 2000 Professional, and Windows Server 2000.

Microsoft’s previous guidance to customers on when they should upgrade their PCs stated that “if you have not already upgraded, we recommend that you upgrade immediately.”

But that guidance did not say that customers should wait until they had upgraded their machines to the latest version of the operating system.

That guidance was only issued for those users who purchased the machines with the hardware necessary for the upgraded version of OS to install.

“For all machines that we sell, we only distribute security updates when they are required for OS upgrade, such as in the case of Windows Server 2008 R2 and Windows Vista SP1, or in the Case of Windows XP Server 2003,” the company wrote in its new guidance.

Microsoft also said that customers could request that the patches be delivered to them at any time, but that customers were not required “to wait for Windows 10 to roll-out patches.”

“If your machine has been configured with a previous version of Microsoft Windows, we strongly recommend that it upgrade to a current version of that OS,” the spokesperson said.

The security patch issued by Microsoft has been available for download for a few weeks now, but it’s not clear whether any users have yet installed it.

Windows 10 is the most popular operating system in the world, and has become increasingly popular over the past few years.

It has grown to include more than 100 million devices, and more than 80 percent of all PCs sold in the US are running the OS.

Microsoft said that it is “working with partners to provide the latest and greatest updates for the Windows 10 operating system,” and that it will release a patch in the coming weeks.
