Windows 10 has been available since this morning and you are probably impatient to install it on your machine. This makes sense, and the good news is that you don't have to be a field mice virtuoso to complete the operation. The assistant developed by Microsoft is extremely well designed and ultimately aimed at all audiences.
However, before you start, know that it is best to start by tidying up your computer and backing up your files.
I have also mentioned this point (and others) in this article . I highly recommend that you start there to avoid unpleasant surprises.
Step 1: check its configuration
Windows 10 is pretty straightforward to install, but you still have to meet certain conditions.
The first has been known for a long time. To take advantage of the free update, you must have a computer running Windows 7 SP1 or Windows 8.1. And be careful, because you must also have installed all the patches deployed upstream by Microsoft.
Also note that not all editions of these systems are eligible for this update.
If your machine is running Windows 7 Enterprise, Windows 8 Enterprise, Windows 8.1 Enterprise, or Windows RT and Windows RT 8.1, then you will not be able to enjoy it. Same thing if you don't have a valid license or if your computer belongs to a domain.
Also, make sure you haven't turned off Windows Update. If you have, there is little chance that you will be able to update your machine …
Step 2: reserve the update
If you meet all the criteria, then you should see an icon appear in your system taskbar asking you to recover Windows 10.
You just have to click on it to reserve the update and to launch the associated wizard.
If this famous icon does not appear, you can also go through Windows Update to download the update. Be careful, however, because Microsoft has opted for a gradual deployment . So not everyone will be able to install the final version of Windows 10 today.
Good news however, the Insiders will be served first. Who says loyalty doesn't pay off?
Step 3: start the installation
First of all, the installer will check your configuration to determine if it is capable of running the system.
It will then launch the installation which will take between half an hour and an hour depending on your configuration and the state of your system. It will be preferable not to launch the update before an urgent appointment, therefore.
As mentioned above, the wizard is well designed and the operation is almost completely automated. It will take place in three distinct stages: copying files, installing features and drivers, and configuring settings.
At this point, the system will ask you various questions. It will ask you to configure your account, for example, or to select a WiFi network.
And then ? It will start to configure your desktop and applications. There, you will have to wait about ten minutes before taking control of the system.
Bonus: what if there is a problem?
Microsoft has also posted a procedure online allowing anyone to manually check the configuration of their computer to be sure that it meets all the conditions required by Windows 10.
You will have to start by opening Notepad and by copying these few lines (beware of jumps) into a new document:
REG QUERY "HKLM \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ AppCompatFlags \ UpgradeExperienceIndicators" / v UpgEx | findstr UpgEx if "% errorlevel%" == "0" GOTO RunGWX reg add "HKLM \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ AppCompatFlags \ Appraiser" / v UtcOnetimeSend / t REG_DWORD / d 1 / f schtasks / run / TN "\ Microsoft \ Windows \ Application Experience \ Microsoft Compatibility Appraiser" : CompatCheckRunning schtasks / query / TN "\ Microsoft \ Windows \ Application Experience \ Microsoft Compatibility Appraiser" schtasks / query / TN "\ Microsoft \ Windows \ Application Experience \ Microsoft Compatibility Appraiser" | findstr Ready if NOT "% errorlevel%" == "0" ping localhost> nul & goto: CompatCheckRunning : RunGWX schtasks / run / TN "\ Microsoft \ Windows \ Setup \ gwx \ refreshgwxconfig"
Then, you will have to save the file under the name “ReserveWin10.cmd” and store it in a place that you will find easily.
Then launch the command prompt with administrator privileges and type the command “C: /My-Dossier/ReserveWin10.cmd”. The tool will run for about twenty minutes and it will scan your entire system. If it fails and if it leads to an infinite loop, then your machine does not meet the prerequisites set by Microsoft.
Note that the entire procedure is described in detail on this page .
Unfortunately, this article has few visuals. I have migrated my test machine to the Technical Preview for quite some time now and I have not thought of keeping the photos taken on this occasion.
I thought about switching my girl's computer to Windows 10 in her absence, but something tells me that she wouldn't have forgiven me.
