For those running the Windows 10 1709 release you will note that you will receive two unusually-named updates.
The first, as observed by several posters in the Microsoft user forums, is that the Malicious Software removal update is labeled “Windows Malicious Software Removal Tool for Windows Insider Preview and Server Technical Preview (KB890830)”. All of the impacted folks have never installed the insider preview versions. It appears that someone at Microsoft merely named the update incorrectly.
The second naming problem also shows up only on the Windows 10 1709 release. For those running the 64-bit operating system, you will see is that the patch is named with the AMD64 name in the patch naming causing many to question why it’s being offered to their Intel 64 bit machines. AMD64 is the official name for the 64-bit platform and does not mean that it’s only applicable to AMD processor chips and not Intel chips. Normally the naming of the patch is merely “64-bit” and does not refer to either Intel or AMD.
Bottom line: It’s merely a naming issue and the updates are safe to install.
What to do: Install these updates at this time.
