Hi, thank you for your reply. Yes, that is another way to address the issue. For now, I suggest waiting for the next Windows update.

The latest security update to Win 11 (11th March 2026) KB5079473 has caused my computer to fully crash 3 times. I have unloaded but it tries to reload. The crashes required a complete reboot of the computer with loss of unsaved data.
How do I stop it reloading?

Ecbert 25 Reputation points2026-03-15T13:33:47.47+00:00 Same is happening to me. It has happened 2 times. I think my suggestion would be to uninstall the update.

Rod Hills 10 Reputation points2026-03-18T14:36:50.1766667+00:00 The update broke my IPP printing to wifi HP Printer.
Removed security patch and got printer functionality again.
How do I prevent windows update from re-installing the patch?

Gabriele 5 Reputation points2026-03-18T14:57:51.65+00:00 (KB5079473) (26200.8037) update gives a fatal error!
Hypervisor_ERROR
DO NOT INSTALL THIS UPDATE... avoid it, remove it, if it gives "installation error", leave like that... you have just missed a bullet. if you get the Hyperviros error, go in the cmd as administrator and paste the command "bcdedit /set hypervisorlaunchtype off", then restart the pc.

Matt 5 Reputation points2026-03-22T14:37:22.2466667+00:00 Same issue here. In my case, the system locks up, forcing me to do a hard reset. No issues after restoring from backup and disabling Windows updates. I'm keeping updates disabled until Microsoft gets their act together.

William Bybel 15 Reputation points2026-03-16T01:59:17.4766667+00:00 This all been but confirmed by Microsoft themselves. Just like a previous update where they were slow to admit fault. This is a bad update and needs to be blocked by everyone. It's not just crashing PCs its taken over Video drivers and making expensive video cards catch fire and burn up. So make sure you block KB5079473 March 11 2026 update and shut off your windows updates for as long as you can.

2026-03-18T19:46:31.9433333+00:00 Rod: same as some other advisors. Turn off automatic updates, I have turned mine off for a month and stopped the immediate attempt to reinstall the update when I had removed it. I noticed that you can still independently update Antivirus and things like that.

Maureen Parisi 0 Reputation points2026-04-10T12:50:34.28+00:00 I have had a problem for a few weeks with the Klondike game in the Microsoft Solitaire Collection (paid subscription) freezing. I've uninstalled, reinstalled, rebooted; I've updated Windows entirely and rebooted. I've done the repair/reset.
I have NOT done this blocking of KB5079473. I found something else online that said to uninstall updates, and find KB5079473. I will try that. Have people had success with this?

2026-03-16T06:57:53.1366667+00:00 It appears that my Minidump file was not the issue. So I have blocked updates for one month. Hopefully Microsoft fixes the problems by then. Can they also make the updates optional so we can install them at leisure once we are kind of sure that it is safe?

Annarki19 5 Reputation points2026-04-02T10:25:53.7533333+00:00 Yeah they do it for LTSC version of windows. But they put experiments on us (regular users) before they send the updates to corporates.

2026-03-12T04:13:45.07+00:00 Hi, I'm Bernard, a fellow Windows user. I'm happy to help!
The KB5079473 is a security update patch for the PC, since your PC is crashing. Can you please check if you have Minidump files on the PC so I can further examine the root cause of the issue?
Press Windows key + E (To open File Explorer)
Click "This PC" > then follow the file path:
C:\Windows\Minidump
Copy the Minidump files and save them to another location, like the Desktop or Documents.
Then please upload it to Cloud storage like OneDrive or any cloud storage you are using, and please share the shareable link here.
To upload and share the link using OneDrive:
Go to this link: https://onedrive.live.com/, then upload the file.
Then, provide the shareable link by following the steps from this link: https://support.microsoft.com/en-us/office/share-onedrive-files-and-folders-9fcc2f7d-de0c-4cec-93b0-a82024800c07
