Reader Question:
“Hi Wally, I installed Windows 10 today and its telling me that my Windows 7 code is invalid. I had Windows 7 installed on my computer and I know that this code works. Whats the problem?” – Kayla M., Canada
Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:
- Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
- Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
- Step 3 : Click “Repair All” to fix all issues.
Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.
Wally’s Answer: Many people are getting the Windows 10 upgrade these days. Microsoft said that around 14 million computers were already using Windows 10 within one day of its release. With all these people installing Windows 10, there are also some people who have encountered error 0xc004f050 while upgrading.
Problem
Installed Windows 10 on a computer running Windows 7. When it asked for a key, a working Windows 7 key was given but it says error 0xc004f050, the key is invalid and won’t let the setup complete.
Solution
Here are some ways to fix Error 0xc004f050 while upgrading to Windows 10:
How Do I get A Windows 10 Key?
When you use Windows update from within Windows 7 or Windows 8 to Windows 10, then what happens is that your existing license key gets registered with Microsoft’s servers.
They store the computer’s hardware information and the Windows 7 (or 8) key along with a Windows 10 certificate. All of this is stored online, and your Windows 10 key is actually not a separate key if you upgraded.
Upgrading To Windows 10 From A USB Or DVD
If you have used Windows update then you should be able to install Windows 10 without a key. But don’t worry if you haven’t tried to upgrade using Windows update. You should still be able to install Windows 10 as long as your computer has been activated with either Windows 7 or Windows 8.
You can download the Windows 10 Media Creation Tool from Microsoft’s own website by clicking here. You can run this to get the ISO or make a bootable Windows 10 installation DVD or USB.
How To Avoid Getting Error 0xc004f050 When Upgrading To Windows 10
When you use the Windows 10 DVD or USB to run the setup, do a clean install only if you’ve already upgraded to Windows 10. Skip the product key box when it appears. It should appear twice in the installation. Later, the setup should look online for your computer’s information and activate Windows 10.
