• Open up a command prompt (Start -> Type "cmd" -> Hit Enter)
  
• Type "net stop wuauserv"
  
• Type "net start wuauserv"
  
• Run updates again

Sometimes the Windows Update service stops working so a restart of it usually helps. If that doesn't work, let us know.

Thx for the tip but it didn't work :/

Did you attempt manually installing the update yet?

You can find the installer for that specific update, here: https://www.catalog.update.microsoft.com/Search.aspx?q=kb4041691
Pick: 2017-10 Cumulative Update for Windows 10 Version 1607 for x64-based Systems (KB4041691)

If you can't get the installer to start on the above update, you might need to install this one first: https://www.catalog.update.microsoft.com/Search.aspx?q=kb4038782
Pick: 2017-09 Cumulative Update for Windows 10 Version 1607 for x64-based Systems (KB4038782)

Re-do the command prompt stuff, but after you disable Windows Update, clean this folder out: "X:\Windows\SoftwareDistribution\Download"
Replace Drive X with the drive Windows is installed to.

Re-enable Windows update and IMMEDIATELY reboot your computer.
That SHOULD clear out the corrupted updates & let you patch Windows. IF that does not work, make sure Internet Explorer 11 is enabled (Programs & Features - Turn Windows Features on or off). NO other browser will let you get the needed patches.
