Windows 7 Updates appear 80092004 錯誤

Do not know when to start,Freshly installed Windows 7 In the month when the latest update rollup updates,Will jump 80092004 Error message,If the update of the month to cancel out,After re-examination,Change the update rollup update last month,As will jump 80092004 Error message。Today spend a lot of time to climb with the text test,Finally finally identify the problem。

 
 

In fact 80092004 The error is related with the verification of the update file,So is not necessarily what causes,In my situation it,Because this year,Mounting the SHA1 authentication encrypted file into SHA2,SHA2 problem has occurred in the verification of this,So there 80092004 錯誤。FromMicrosoft's explanationView,Windows 7 You need to install KB4474419 and KB4490628 two KB,Checked my computer,There are installed KB4474419,But missing KB4490628,So long as the Microsoft Update Catalog Download and install KB4490628,You can normally install rollup patch kit。
