Alert! After installing the CPU vulnerability patch in Win7, a blue screen is displayed! Security mode cannot be used. win7 vulnerability patches

After reporting last week that Windows 10 has accumulated an update of KB4056892, which causes incompatibility with AMD Athlon 64 x2 processors, it has recently reported that the upgrade of KB4056894 released by Microsoft for Windows 7 has failed, the error code 0x000000c4 is displayed on the blue screen. A variety of common repair solutions have not worked yet. The only solution is to remove the patch and choose to ignore it Until Microsoft officially fixes it.

The KB4056894 patch mainly fixes Meltdown and Spectre vulnerabilities in Windows 7. After you install the update on Windows 7, the following error occurs:

* ** STOP: 0x000000C4 (0X0000000000000091, 0x0000000000000000, 0xFFFFFF80002C4EFC0, 0x0000000000000000)

Then the user cannot enter the security mode. The user needs to recover the program boot through RollupFix, and then uninstall the latest patch. However, Windows Update will remind you to install the KB4056894 Update again.

Some Windows 7 users discuss this issue on TechNet. Some people suspect that the blue screen is caused by compatibility problems with installed anti-virus software, therefore, Microsoft has previously said that this patch is only applicable to systems compatible with anti-virus software. However, this problem also occurs for Windows 7 users who have not run any third-party security solutions.
