Issue abstract: Norton 360 won’t load
Detailed description:
Product & version number:
OS details: Windows 11
What is the error message you are seeing?
If you have any supporting screenshots, please add them:
Microsoft said I couldn’t upgrade from Windows 10 to 11, but I did a workaround. Windows 11 mostly works, but Norton 360 is not working. Is this a problem with other users?
@Spiderspoon We need to ask the following questions:
-Did you use Rufus or other tools to create an install ISO that bypasses the hardware requirements to clean install / upgrade? Or.
-Did you upgrade then edit the system registry to get the upgrade in place?
-Does Windows download and install updates or have those been denied? What is the version and build of Windows 11 you have installed?
-Are you clean installing Norton 360 or is there an install that was on Windows 10 when you upgraded?
-Do you have any screenshots to share of what you are seeing regarding Norton?

Or.
-Did you upgrade then edit the system registry to get the upgrade in place? Yes
-Does Windows download and install updates or have those been denied? What is the version and build of Windows 11 you have installed? Windows Update works. Windows 11 Home 24
-Are you clean installing Norton 360 or is there an install that was on Windows 10 when you upgraded? I can’t remember how I installed Norton 360.
-Do you have any screenshots to share of what you are seeing regarding Norton? No screenshots.
I restarted the laptop and reopened Norton 360 and it started a cloud backup. The other day that went on for hours and I had to cancel it. Much of the time N360 just freezes and I can’t end task in task manager. I have to restart the computer.
I suspect that Windows 11 is not a good idea for that laptop. It has TPM 2.0, but I think the problem is with the number of cores. The CPU has 2 cores.
I am considering uninstalling Windows 11 and sticking with Linux on that computer.
I am currently typing on a desktop computer with Windows 11 and N360 is working fine.
Some other programs seem to run a bit slowly on the laptop that shouldn’t be running Windows 11. It was just an experiment ahead of October 25. I won’t be scrapping the computer, but I am prepared to ditch W11 on it though.
@joannef1224 If your laptop doesn’t have a TPM 2.0 chip, nor support secure boot, and, your CPU isn’t listed on these lists for Intel and AMD then no. Windows 11 cannot be installed via Windows Updates. As did Spiderspoon, there are work arounds to get Windows 11 to install, Microsoft has blocked many of those by tailoring the ISO ( installation image ) needed for installation media creation.
Intel CPU’s:
AMD CPU’s:
Note: Because of bypassing installation blocks for Windows 11, editing the registry, one or both those can cause third party software not to install or even run correctly. Norton uses the Windows system kernel ( core ) to provide functionality for its services. Those may be disabled with a bootleg install of Windows 11 much as running an Insider Build of Windows 11. Norton does not guarantee if it will install nor function properly.
Do you by chance know what CPU you have? If you can post the model number I can look it up for you.
What is the exact, full model number of your Dell PC? I’d like to check out whether it has TPM on the MB as shipped from the OEM for you. I STRONGLY suggest imagining your drive C:\ before considering performing an upgrade for unsupported hardware.FULL recovery image not a backup.
Your CPU is 2 cores - 4 threads meaning, its hyperthreaded running as if it has 4 physical cores. It is indeed NOT on the supported CPU listing by Microsoft. Weird thing is that it DOES support the SSE4.2 that is a requirement for the POPCNT instructions set on the CPU. That is a requirement for installing the 24H2 update that Microsoft is pushing older 24H1/2/3 installs to. So why does this CPU not meet the requirements WHEN older slower CPU’s are on the list? Your guess is as good as anyone’s because the CPU checks all the boxes Microsoft requires. My boilerplate is, Microsoft is heavily focusing on AI, Co-Pilot enablement, and Recall. These three things on the part of Microsoft, have been determined that certain CPU’s aren’t going to be able to run future upgrades in that repect.
But, does your motherboard have a TPM chip and is it enabled? Perform this check to see if you have the TPM chip and its not enabled. Its usually enabled in the system BIOS settings:
Next. Does your computer have and support UEFI and Secure Boot in its BIOS? Note: Backup or image your hard drive BEFORE performing this step, you CAN lose all your data changing from Legacy to Secure Boot.
Your graphics has to support Direct X 12 2.0 or higher. You can check this by using the following:
*** My boilerplate is, use your devices as is until, you can’t. OPatch offers their services and they are not bank breakers. Check them out. When the time comes, I will use the registry trick if its not disabled, along side OPatch. Some of my older older devices with W10 most likely will go to a Linux installation. I recommend reviewing this article.
@Spiderspoon Remove and reinstall Norton using the remover tool: Remove first and reboot. Manually remove any folders with the names Norton, Avast and Symantec, reboot. Download and install Norton again from your Norton account.
As we shared last October, for the first time ever, you can enroll your personal Windows 10 PC in the ESU program and receive critical and important monthly security updates for one year after support ends in October. Today, we’re introducing additional free enrollment options and the simple steps to get started.
Extended Security Updates for Windows 10:
For individuals: An enrollment wizard will be available through notifications and in Settings, making it easy to enroll in ESU directly from your personal Windows 10 PC. Through the enrollment wizard, you’ll be able to choose from three options:
Use Windows Backup to sync your settings to the cloud—at no additional cost..
Redeem 1,000 Microsoft Rewards points—at no additional cost..
Pay $30 USD (local pricing may vary).
Once you select an option and follow the on-screen steps, your PC will automatically be enrolled. ESU coverage for personal devices runs from Oct. 15, 2025, through Oct. 13, 2026. Starting today, the enrollment wizard is available in the Windows Insider Program and will begin rolling out as an option to Windows 10 customers in July, with broad availability expected by mid-Augustxii.
Yeah, that’s probably the issue. Norton might not fully support Windows 11 if it wasn’t a proper upgrade. I’ve seen similar problems when Windows 11 isn’t officially supported on the hardware.
