[SOLVED] Help resolving sfc and dism errors prior to Win 10 upgrade

[calanan]

I'm looking for help resolving some unspecified (at least to me) corruption on this Windows 8.1 x64 PC before I attempt upgrading it to Windows 10.



Though I am seeing no obvious problems with Windows Update, I am seeing errors with both sfc and dism and would like to try to resolve them before upgrading. I've had similar issues of corruption on other machines in the past that have caused them to get caught in Recovery Console loops when upgrading to Win 10 and I'd like to try to be more proactive this time around.

Below is output from sfc and dism, please let me know if you need any logs or other output, thanks!

Hi calanan :)

My name is Aura and I'll be assisting you with your issue. You don't need to solve corruption issues under your Windows if you upgrade to Windows 10 using the Media Creation Tool, only if you intend to upgrade via Windows Update. However, using the MCT is better since the success ratio is higher.

Solved! Thanks again for your great advice, Win 10 installed via MCT without any issues and both sfc and dism come up clean!
