Recently, Sangfor has received many inquiries from customers about the outbreak of blue screens in Win7. The content roughly refers to "Win7 has ended its service, Microsoft will no longer update patches, computers collectively have blue screens, the error code is F4, blue screens and vulnerability patches There are correlations, etc., and appeals to users not to fix vulnerability patches."

#However, according to the problems collected from Sangfor, large-scale Win7 blue screens have not occurred in enterprises. We traced back and found that this problem first appeared in personal and Internet cafe environments. There are indeed some individual users and network administrators seeking help from security vendors.

Regarding whether vulnerability repair (patching) will cause a blue screen in Win7, we have repeatedly verified that there is no inevitable correlation between patching and blue screen in Win7 (that is to say, patching will not cause a blue screen in Win7). It must lead to a blue screen in Win7). We also consulted Microsoft officials as soon as possible, and the other party also expressed that they did not know much about this.

Since the patch is not necessarily related to the Win7 blue screen, and it rarely occurs in corporate environments, and a certain scale of blue screen phenomena occurs in personal and Internet cafe environments, we highly suspect that it is related to Windows pirated systems. Finally, we discovered a coupon plug-in, CouponUpdate.exe, in the Ghost system. This plug-in would cause a system blue screen when updating and upgrading.

We recommend that users use Microsoft’s official original image to install the operating system to avoid using pirated or ghost systems. The following image shows the installation path of the CouponUpdate.ex updater.
