Microsoft has made something of an odd move in reissuing a pair of updates for Windows 10, which apparently had something wrong with them in the original release. However, the firm has failed to clarify exactly what the issues with updates KB4458469 and KB4457136 were.

These updates were first pushed out at the end of last week (September 21), and then redeployed yesterday. KB4458469 is for those on the latest version of Windows 10 (April 2018 Update), whereas KB4457136 is for those still running the Fall Creators Update.
