best third party update tools for windows 10?

Hello sikelo,

Do you mean for Windows Update?

If so, do you get an error message, and what update(s) is this happening with?

If you like, you could try resetting Windows Update for now to see if that may help.

Reset Windows Update in Windows 10

Hi, whether that willl help you depends on what is broken- if it's Windows Update that is broken, a 3rd party utility may work - or not. If it's applying the update or in particular a feature update (upgrade) that fails, that can be another matter entirely.

Suggest you provide:
- full details of the PC in question
- its Windows build number
- full details of the failure you are experiencing and which update is failing
- a screenshot of your Update History
- the result of running the Windows Update troubleshooter (which you can find via Settings)

Noted you have more than this problem- you have just posted this:

repair windows defender in in win10 ?

Is this the same PC? If so, please handle both problems in the one thread - here- rather than have two lots of people trying to fix the same PC. Thanks.

Assuming it's the same PC, perhaps simply best to do an in-place upgrade repair install which keeps all progs and data.
You will need an iso file of the same build as you now have.
