It’s been two days since Microsoft officially rolled out the Windows 10 Anniversary Update, but some users managed to download and install the update only few hours ago. As surprising as this may sound, there are users out there still struggling to download the Anniversary Update package.

When users hit the “Install update” button, the download starts but somehow gets stuck halfway through or at 99%. This issue occurs when users try to upgrade using Windows Update as well as when they use the Anniversary Update ISO file.

Sometimes what appears to be a stuck download is only a process taking longer to finish due to various elements, such as your Internet connection speed or the available memory on your computer. However, there are cases when the Anniversary Update download still remains stuck despite user actions: formatting all the partitions on the computer, upgrading the drivers, or resetting the computer altogether.

The Windows 10 Anniversary Update download gets stuck for all users, from developers to regular computer users, on 32-bit versions as well as on 64-bit versions. However, it appears that this issue is indeed prevalent among Windows Pro users.

Windows 10 Pro users complain Windows 10 1607 download process stalls

It just randomly hangs (stalls, no cpu activity or so on). Sometimes downloading one update.. sometimes another.
I have not seen this behavior with previous version of Windows 10 (1511).

Another user offers more details about the workarounds he tried, to no avail.

after an update version aka new windows 10 version, i check my window update , and its stuck.
on downloading 0 %. already check windows update servicing, sfc, trouble shooting, dism, nothing works for me..

If the download process stalls when using Windows Update, try to install the Anniversary Update manually. For the time being, we haven’t been able to find any fix for the situation.

If you are trying to download Windows 10 version 1607 from WSUS, you need to wait a bit longer because the Anniversary Update will be available via the System Center Configuration Manager or Windows Server Update Services (WSUS) starting August 16, 2016. In other words, download stalls are normal if you use the WSUS.
