Windows RE update Error 0x800f0805

Hello community,

I have a problem with the windows security update KB5050411 (winRE). After the downloading the install never start, it stay at 0% and after some minutes i have the error 0x800f0805.

 

My WinRe partition is of 1,49 GO (NTFS partition 3 of Disk 0)

 

That create the impossibility to download and install the next update (cumulative update KB5053606).

 

The error 0x800f0805 it's for the two update and i try to manually install the cumulative update and i have the same error via DISM at 6% of installation an error pop.

 

The for your help,

 

Alex.

  • I found the solution : I made a reset upgrade of windows 10 using iso file : 

    • Download the media creation tool
    • Choose iso file
    • Mount the iso
    • Launch setup
    • Choose keep files and applications
    • Let the installation finish
    • Launch the windows update
    • Restart and it's all 😁
