Cannot upgrade Windows 10 Home to Pro edition

We couldn’t upgrade your edition

Try upgrading your edition of Windows again or contact your your system administrator or Microsoft. Error code: 0×0

When you arrive on this post, you might have been frustrated with above error message when upgrading Windows 10 Home edition to Pro edition. Without too much talking, here is the solution:


Yes, it’s. Whatever your antivirus program, uninstall it first before entering Pro edition key for the upgrade.

In my case, my Asus ROG GL502VT came with McAfee LiveSafe. It had successfully destroyed my day until I realized that it’s the cause of the issue.

You can reinstall your Antivirus program again after the edition upgrade completed successfully.

Although it’s recommended that we install Visual Studio versions in the order in which they were released (for example, install Visual Studio 2012 before we install Visual Studio 2013) as mentioned in, there is possibility that we have installed Visual Studio 2013 before we know that we need to install Visual Studio 2012.

It happened to me last month. I actually more than happy to have Visual Studio 2013 only in my computer as I can also use it to open Visual Studio 2012 projects. But in the end I need to install Visual Studio 2012 because one of my teams are using Visual Studio 2012 and I don’t want any incompatibilities or project upgrades affect them.

If you have to install Visual Studio 2012 after Visual Studio 2013 for any reason, don’t worry, it can be installed without any issue.

I have been using this configuration almost a month and there is no issue at all. I mostly use them to do ASP.NET projects (and related, such as class library, etc) and I’m sure there is no issue with other project types too.

Today I was debugging ASP.NET website and got very annoying issue. The website has file download feature and anytime I download the file IE9 couldn’t open it – the file was missing before the PDF application could open it. It did work on FF and Chrome.

I have cleaned-up Temporary Files directory and also ASP.NET temporary files (C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files) but no luck.

Later I realized that by changing the debugging port for ASP.NET Development Server to any new number solved the problem. But I didn’t believe that it’s the real solution. Then after playing with IE settings a bit I found that this setting caused the problem.

It was set to Automatically by default.

You can set it to Every time I start Internet Explorer but I prefer Every time I visit the Webpage for my need, both will work.

Hopefully this will help anyone having the same issue as I faced.
