How to switch from Windows 10 Home to Windows 10 Professional without reinstallation

Upgrade your version of Windows without having to completely reinstall your PC's operating system. Switching from a version of Windows 10 Home to a version of Windows 10 Pro isn't as complicated as you might think. If you imagined a complete system reinstallation to switch from one version to another, you were wrong. Microsoft has done it right. Upgrading a Windows 10 Home to a Windows 10 Professional is done by simply changing the product key saved in the system settings. You will therefore only have to buy a Windows 10 Professional product key that you will enter in place of the one already present on your machine. Even better, if you already have a Windows 7 Professional, Windows 7 Ultimate, or Windows 8 / 8.1 Pro product key, for example from a machine that you no longer use, you can normally use it to upgrade your Windows 10 Home to Windows 10 Professional. Windows can be unpredictable at times, so be sure to make a full backup of the data stored on your computer before st

How to enable hidden "Best Performance" mode in Windows 10?



Windows 10 includes a hidden power mode, usually reserved for workstations, which can be activated for the Home and Pro versions. Here's how.

Depending on how you use your computer, you can configure Windows to use a power plan that will prioritize either performance or energy savings.


Since Windows 10 version 1803, Microsoft has introduced a new power plan, Best Performance, intended primarily for workstations running Windows 10 Pro. To activate it, go to Windows Settings, then in the System menu, enter the Power and standby section.


At the bottom of the window, click Additional Power Settings. The Power Options window should then display an Ultimate Performance option that you just need to select to activate the mode.


But other machines running Windows 10 Home and Professional are by default deprived of this power supply. If the option is present in the operating system, it is hidden but can still be activated with a few clicks to use it on any PC. Here's how.


1. Open the command prompt as administrator

Click on the Start menu and search for Command Prompt. Right click on it and choose to run it as administrator.


2. Enter the command

In the Command Prompt window that appears, enter the following command using copy and paste and confirm with the Enter key:


powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61


The Command Prompt should then confirm the activation of the power management mode graphical interface (GUID), thereby confirming the addition of the option in the dedicated power management panel.


3. Activate the Ultimate Performance power plan

Click on the Start menu and enter Windows Settings. Access the System menu and go to the Power and standby section.


Scroll through the options and then, at the bottom of the page, click Additional Power Settings.


In the Power Options window that appears, choose to Show additional modes by clicking the arrow on the right.


Then select the Best performance mode to activate it on your computer. Used on ruggedly configured machines, this power mode will provide better performance in the most resource-intensive tasks.

How to use Meet Now, Skype video calling service for free?

Skype has just integrated a solution to create or join video meetings on the fly with or without registration. Here's how to use it. With the confinement imposed on all by the Covid-19, downloads of messaging applications to initiate video calls have exploded. And if in the mid-2000s, Skype was the benchmark in terms of videoconferencing solution, the application acquired by Microsoft in 2011 has lost its splendor and has been overtaken by new, more aggressive players offering an interface and more modern features that have won over the general public. To return to the front of the stage, the application has multiplied the updates bringing new features such as the ability to blur the background during a video call, or to translate on the fly conversations held in other languages. But in an attempt to counter Zoom, whose use has exploded in recent weeks, Skype has launched Meet Now, a feature to launch a video meeting on the fly, accessible both from the application and from a web b

How to enable encrypted DNS in Microsoft Edge and protect your web browsing

Help protect your privacy by changing Microsoft web browser settings to force DNS-over-HTTPS to be enabled. Microsoft announced a few weeks ago that it wanted to integrate native support for the DNS-over-HTTPS protocol on Windows 10. Thanks to it, the protection of the privacy of its users will be reinforced thanks to the automatic encryption of DNS requests. While at this time the availability date of such a feature in Microsoft's OS is unknown, users can already activate the feature in the Microsoft Edge web browser. Like Chrome and Firefox, Microsoft's new browser version supports encrypted DNS. However, the feature is not available by default and requires that you activate a specific setting within a hidden menu. Here is how to do it. 1. Access the flags The new version of Microsoft Edge is based on Chromium, so it shares a number of elements with Chrome. This is the case for example with flags, hidden experimental functions that can be activated. To activate encrypted DNS
