Hello Kapil Arya, My issue is still not solved even after doing all three steps you told in video. The second step you told was about registry but there was no security health services registry there. Please help me as soon as possible.
^^ Looks like your system is infected thoroughly. Suggest you to perform a malware scan.
It didn’t work for me…I don’t know what to do now..please help me
Didn’t help me yet either. The Windows Security screen is always blank. Blank and white.
^^ if you’re on Windows 11 23H2, and issue appeared after reset/clean install, refer this fix: https://www.kapilarya.com/fix-cant-access-virus-and-threat-protection-on-windows-security
Sadly doesn’t work. We build devices in a corporate environment, fails evetime that the devices are domain joined.
Happens with W11 22H2 and W11 23H2. Windows 10 is not affected
Its a Microsoft issue and not a system infection, the above steps won’t work if you have domain joined devices and are seeing this issue.
