Duplicated installation of KB4457128
Early on today, in the Microsoft Answers community there was an issue reported regarding the double installation of KB4457128. Replies came shortly to confirm it is not a single case, but many observed this problem in the Windows Update History.
Apparently, there is no critical harm yet reported on any computers whatsoever, but a big sign of concern from a few Insiders:
The only issues so far coming from Release are Apps window sizes revert to default on the upgrade and still turns on “Show me suggested content in Settings” after turning this to off in Release. Most of the other issues have cleared up. This build shows promise. Will clean install this one in laptop.
Looks like Microsoft could have prevented this, but omitted to test these Cumulative Updates with the Insiders. Now the whole world has to deal with this, as one of the Insiders claims on the Microsoft Answers community:
This is what happens with MS not giving these CU to Insiders on Just Fixes as they once did prior to releasing. This could have been prevented. Now the whole world has to deal with this.
Other users have confirmed the double install, although observing that computer is running great.
You can also make sure to check your Event Viewer for any warnings or critical issues since signing in after this update. Also, check Security and Maintenance log for any problems.
One of the Microsoft Agents followed this thread and guaranteed that the engineering team knows about the issues now. It might be just a matter of time for the new patch to be released and fix this. Keep an eye on our news category to be informed.
File Explorer freezes after installing KB4457128
We have noticed that File Explorer was running quite slow today and scanning the forums appears that we are not the only one to see some problems. If you also happen to have these issues, do not hesitate to leave us a comment in the box below.
Try to organize your files in the File Explorer, and check its behavior even with few files in a folder. Pay attention to the speed it operates simple commands and if at any time appears to be frozen.
A few users have checked if programs that take lots of CPU/memory resources were run when these problems occurred. Also, reassured that no file transfer or other operations were actioned at that time.
How to fix File Explorer issues after installing the update
We recommend running a SFC/scannow to check and repair system files. Also, perform a refresh or reset for Windows. If you reset your system, you have the option to Keep personal files in the setup process.
