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.

How to Rearm and Extend Free Usage (Activation Grace Period) of Windows 7 to 120 Days

‘Rearm’ trick on Windows 7 is done using the similar commands and steps with Windows Vista. Follow these steps to reset and extend activation grace period from 30 days to 120 days in Windows 7:

Type any of the following commands into the command prompt, and then hit Enter:

Code: sysprep /generalize slmgr.vbs –rearm rundll32 slc.dll,SLReArmWindows slmgr /rearm[/quote] As rearm only works for 3 times, make sure the command is only been run when the 30 days countdown of evaluation period is almost expired.

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
