Fix – Windows 10 update KB3189866 stuck at 45%

If you’re running Windows 10, it’s yet another sad week. Microsoft messed up again and their latest 400Mb+ update (KB3189866) doesn’t even download properly. Most people (including myself) are stuck with an update progress stuck at 45%…

Fear not! Stop waiting and simply install the update manually in just a few clicks. Here are the direct links to download it (select the appropriate system architecture):

32 bit:
Cumulative Update for Windows 10 Version 1607 for x86-based Systems (KB3189866)

64 bit:
Cumulative Update for Windows 10 Version 1607 for x64-based Systems (KB3189866)

Run the installer and after a few restarts, you’ll be good to go again.

For some reason, this identical update when downloaded via the Windows Update Catalog web downloader, uses another filename (adds the prefix: “AMD64-all-“)… It’s strange as the files are IDENTICAL! I double checked for you and and these Checksums proves it:


Fun fact! The update’s filename contains its own SHA-1 checksum hash! (2c3e91a8162269579c8bf26a502c620d41efef0d)
