When in win10:

• Update&security -> Windows update -> Finding update... .... .... ....

Planning to download the latest Win10.ISO (vers.1803) and manually update:

Win10: windows update stuck at never ending loop ?

Hello
Win10: Windows update is stuck at never ending loop ? ( Last Win10 updates in 2017 ). Can't update the laptop. Genuine Win10 on a HP 2015 17.3" laptop that originally had Win8. ( CPU:AMD A9, GPU:Radeon R5 ).

If I download this below file does it manually install the latest updates of Win10 (=2018 April Update) without losing any files currently on the machine ? ( Mainly paid Office 2013 )
MediaCreationTool1803.exe
