Hi Gabriel,
The 800B0001 error you're seeing it means that Windows Update cannot determine the cryptographic service provider, or that a file Windows Update requires is corrupted.
To try and fix that please do the following:
- Right click the Start button and click Command Prompt (admin).
- Type: sfc /scannow and hit Enter.
SFC is an acronym for System File Checker and the tool will check the integrity of Windows system files for corruption. If any are found, it will attempt to repair the file using the DLL repository.
Sometimes though, SFC cannot repair files and you'll see a message to the effect that file corruption was found, but Windows resource protection was unable to fix some of them.
In that event, use the same command prompt to run the following command. It's advisable to copy this command with a mouse and then right click and select Paste from the menu to paste it into the command prompt.
DISM.exe/Online /Cleanup-image /Restorehealth
When DISM runs, you won't see much happening on screen and for about five minutes, it'll just show a flashing cursor. But eventually, the figure of 20% will appear followed about 15 mins later by 100%. You'll also get a report on whether the tool was successful
or not.
