Shutdown impossible, How to cancel a Norton subscription fan running Update KB5073455
Hi!
I'm running Windows 11 Enterprise, OS Version Dial 87.7.41934 . 68. BIOS version: LENOVO R2SET29W (1.05 ). System model 21S7S0ER00. Intel processor Family 6 Model 181.
After the latest update KB5073455 I'm experiencing inability to shutdown the computer. Also, a very annoying problem since the latest update is that the computer fan is constantly on since startup. Closing the lid of the laptop will not turn the fan off and will continue until the battery runs out. Because of the corporate environment, I am unable to advancedly control the fans, or for example uninstall the latest update until a fixed one is provided. Do you know when can we expect a fix to be released? Thank you already in advance!
Best regards, dhiraj
