Curious, to find out what the hell. Installation on a little problem, win7,64 bit, has been stuck here not moving?
Had to cancel. Installation is still the case the next day.
So download WINDOWS6.1-KB2999226-X64.MSU, installation, still lag;
Then find a variety of solutions, only this useful:

This was because the OS failed to install the required update WINDOWS8.1-KB2999226-X64.MSU.
However, you can install it by extracting the update to a folder (e.g. XXXX), and execute following cmdlet. You can find the WINDOWS8.1-KB2999226-X64.MSU at below.
C:\ProgramData\Package cache\469a82b09e217ddcf849181a586df1c97c0c5c85\packages\patch\amd64\ Windows8.1-kb2999226-x64.msu
Copy this file to a folder
Create a folder XXXX in then and execute following commands from Admin command PROPMT
Wusa.exe windows8.1-kb2999226-x64.msu/extract:xxxx
Dism.exe/online/add-package/packagepath:xxxx\windows8.1-kb2999226-x64.cab
Vc_redist.x64.exe/repair Last command need isn't be run. Just execute EXE once again.
This worked for me.
Install Python-3.5.2-amd64.exe again, success.
