Q: I have a lot of custom software on my “Windows 10 Home” PC that may not work on Windows 11. Therefore, I don’t want to upgrade to Windows 11 until I can get security updates. for Windows 10. But it seems that avoiding Windows 11 is difficult. What do you suggest?
—David Hintz, Blaine, Minnesota
A: There are several ways to avoid having Windows 11 on your PC. And that’s a perfectly reasonable strategy if you’d rather keep using Home or Pro versions of Windows 10 until Microsoft stops providing them with security updates in October 2025.
Here are the methods, which range from reasonable to impractical to risky:
– If your PC does not have a certain computer chip, it cannot handle Windows 11, and you may forget to upgrade. The chip, called “Trusted Platform Module” version 2.0 (see tinyurl.com/2p8urcun), is located on the main circuit board and handles several security-related tasks, such as data encryption. If your PC does not have this chip, Microsoft will not allow you to download Windows 11 to your PC. (To find out if your PC has the chip, see tinyurl.com/26v2ejd6.)
—If Windows 11 is downloaded and installed on your PC, you have 10 days to revert to Windows 10 without losing any personal data. To do this, go to the settings of Windows 11, click on “system”, then on “recovery”. Select “go back”. Follow the instructions and your PC will revert to Windows 10. After 10 days, this process does not work. (See tinyurl.com/nytzp4x8.)
—Windows 11 is installed through Windows 10’s “Windows update” feature, which can be suspended for seven days. If you are willing to pause updates every seven days, you will never get Windows 11. However, you will also not get any other updates, including security ones, so this method is impractical. for anything other than a temporary delay. to get the new operating system. (For more details on this and the following Windows 11 download blocking methods, see tinyurl.com/2p8ph86y.)
—You can turn off Windows 10’s “update services”, which means Windows will never update unless you tell it to. Like suspending Windows Update, it is inconvenient in the long run.
—If you’re using Windows 10 Home, you can edit your PC’s registry, a settings database, to prevent Windows 11 from downloading to your PC. However, I do not recommend making any changes to a PC’s registry because if you make a mistake, the PC may not work.
—Readers using Windows 10 Pro can make changes to “Local Group Policy Editor” that will prevent Windows 11 from downloading. Experts see using Local Group Policy Editor as a better way. sure to make changes to the pc than to use the registry.
Q: I want to install a video doorbell and outdoor cameras, but I don’t know enough about home security systems. Are there any beginner’s guides to home video security?
—Anthony Adamczyk, Manchester, Connecticut
A: Consumer reports from last January contain a buying guide for home security cameras (tinyurl.com/4u4w7x7x). It explains the pros and cons of using wireless video doorbells and security cameras, and how to decide what you need. Tom’s Online Guide for September (tinyurl.com/rjcnx7s8) compares do-it-yourself home security systems, most of which have the option of connecting to external professional surveillance services.
