I have upgraded about 8 machines to Windows 10 this week. Mostly from 8.1, but one from Windows 7.
All of them had a trouble free upgrade and are now running windows 10 successfully. But only one or two would start the upgrade. The rest had errors starting.
I saw error 800240 and error 90020 (or similar?). (Click View update history in Windows update to see your specific error)
My friend Tony had error C1900107 and method #2 worked for him.
I got them all going by doing one of the two things below. Method one worked on approximately 75% of the machines. Method 2, the remainder. I wonder if method 2 would have worked on all of them? I guess I will never know.
NOTE: All of this presumes you are running Windows 7 or 8 and are eligible for the free upgrade.
delete all files and folders in
Step 2 –
Open a COMMAND PROMPT as administrator. (Right click your start button, and it should be a selection there)
Step 3 –
Once at the command prompt, type in the following command:
and press enter. That’s it. If it works, within 3 minutes the update has begun. You can go to Windows Update to see it start.
If its still not going, try method 2.
Step 1 –
You have to figure out if you have 32 bit or 64 bit windows installed. Find MY COMPUTER. Right click it and select properties. Somewhere there is the answer.
Go to this web page: http://www.microsoft.com/en-us/software-download/windows10
Download and run the Windows 10 update from that web page. 32 bit or 64 bit as determined in step 1.
When you run that upgrade utility, it gives you the option of upgrading the current machine or downloading the update. Select the top option UPGRADE THE CURRENT MACHINE.
And you are off and running!
Good luck. If you need more help, you know how to get a hold of me. Thanks for supporting the ads on this page!
