Windows 10: Just upgraded from Windows 10 Home to Windows 10 Professional and show Windows is not Activated

This is on a Dell Inspiron 15 7000 laptop, which is a company issued laptop. I was told to upgrade Windows 10 from Home to Professional. I went to the Microsoft Store, paid for the upgrade. Rebooted the laptop and when I log back in and check under Settings > Update & Security > Activation I see that the Edition has changed to Windows 10 Enterprise but in yellow letters I show the following: "We can't activate Windows on this device because you don't have a valid digital license or product key. If you think you do have a validlicense or key, select Troubleshoot below. Error code:

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.

 

Windows 10 Activation (Insider)

Like Pill Monster said no more Windows 10 keys for Insiders. It was on Microsoft Blog they said that all that stuff is tied to one machine. You can upgrade anytime but never make a clean install. Those people who upgraded from 7 or 8.1 to 10 can do a clean install of RTM and post-RTM builds. A friend of mine upgraded from RTM to 10533 or whatever the latest post-RTM build is (and it activated just fine).

After all MS isn't stupid to give Windows 10 for free.

 

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK
