I have been trying to upgrade my computer to windows 10 for some months now, but no success. 

It downloads, check requirements, starts the upgrade process, then stops with error code C190011F. 

 

Currently running an activated windows 7 professional, service pack 1 with all windows updates applied.

I had for a couple of years ago some malware on my computer that I am pretty confident is gone now, I use malwarebytes, and is currently running Avast Free Antivirus. 

 

Hope to get some help with this.

   fjank,

 

You are always best to have your own Windows media so I prefer to create an ISO or a bootable USB thumb drive, this is what I suggest that you do if you can.

 

If you have your Windows 7 product key** a 4GB or above USB thumb drive or a blank DVD RW and burner see Need to create a USB, DVD or ISO? here

 

** We can help you obtain this if you do not have it available.

Ok, downloaded media creation tool, created an installation for en_us, windows 10, 64 bits to a USB thumb drive, not doing a clean install, so I thought I didn't need to product key, but getting it anyway (it's under my battery), Then I will try to upgrade using the USB as boot disk. Reporting back in a while...

So, the same happened, I got a message I needed to restart the computer in normal mode, and start the upgrade directly from the thumb drive. Doing that I got a regular "Modern Host Process Stopped working..." and I am back to square one.

But, I saw i nice option when I booted from the thumb-drive, clean install of windows 10, without the need to reformat. So I did that, and everything worked like a charm. Of course I need to reinstall the applications I use, and clean up and remove manually the applications I do not use, but I am now up and running on windows 10, finally.

 

Thank you very much for the hint on installing via a thumbdrive!

You are most welcome and glad that we were able to help fjank 

 

Quick question, were you not asked to insert your Windows 7 product key as part of the Windows 10 upgrade procedure.

Yes, during the windows setup an "Activate windows" dialog show up:

"If this is the first time you're installing Windows on this PC (or you're installing a different edition) you need to enter a valid Windows product key. Your product key shold be... bla bla bla. 

 

If you're reinstalling Windows, select I don't have a product key. Your copy of Windows will be automatically activated later. "

 

I punched in my product key, so it seems Microsoft was happy about this.

Thanks for confirming    reason that I asked was so that others who may read your thread can see that you use your Windows 7 (8 or 8.1) product key to activate Windows 10, suggestion for you, run Magical JellyBean Keyfinder (free) to obtain the product key number for Windows 10, write it down and keep it somewhere safe.
