Secure launch, windows ess ad other issues

[leli4]

Hello

I bought a new  b5404cma recently. I had some issues

• In event viewer it says failed to update sbat value.
• Secure launch (a VBS service; not secure boot ) doesn't work
• Windows enhanced sign in security was enabled but then it just disappeared from settings 
• A month ago my pc just froze at Asus logo and I had to force shut down my laptop.

I saw that Asus released a new bios version (306) for my laptop. My question is should I update to the latest bios? In the release notes it just says improved system performance and I don't know if that update could solve my issues.  So should I update my bios?

Thank you for your help.

Unfortunately, if you perform a system restore, the internal data will be lost. Therefore, before restoring the system, it is recommended to back up the data to an external storage device.

Hello,

Could I try the "repair windows with windows update" feature?

@leli4 
Yes, you can also try this method.

This method reinstalls windows but keeps everything right? Does it count as an reinstallation? Should I try the bios update first or this solution?

Updating the BIOS is unlikely to resolve the issue you are encountering. Therefore, it is recommended that you reinstall the operating system and then verify the problem. Since the system you are using was not provided by us at the time of manufacture, we suggest that you directly contact Microsoft for any issues you may encounter.
