Seven things to keep in mind before installing Windows 10

If you have already read our 20 suggestions on things you can do at Easter to take advantage of your days off and you have been struck by get you reinstalling Windows, maybe you have dissuaded the realization of how many things you should check and have ready before you get down to it.

But nothing happens: in this article we will provide you with a complete list So you don't get overwhelmed thinking that you have forgotten something.

Get a Windows 10

It's going to seem like a no-brainer, but one of the first things you'll need to make sure of is have a copy of Windows 10 and of burn it to a USB drive or DVD so you can install it.

My advice is that you use for it the official Microsoft Media Creation Tool, which will allow you both to lower the ISO and to burn it. If you already have an ISO downloaded, you can burn it with third-party tools like RUfus. Here you will find all the information you need to do so.

The copy of Windows, of course, must be legal. If you haven't purchased a Windows 10 license yet, you can do so in several places, starting with the Microsoft Store. If, on the other hand, you already have one but cannot find the product key, below we will tell you how to access that data.

Check if your computer is compatible with Windows 10

If this is the first time you have installed Windows 10 on that computer, make sure it is compatible with the operating system, consulting the manufacturer's website. Next you will have to make sure that the hard drive where you will install Windows has at least 10 Gb free (Although it would be advisable to leave a little more margin).

Prepare for the unexpected

Don't start installing Windows without being prepared for the unexpected ... like, for example, power outages. So, if you have a UPS device, connect the PC in question to it; And if it's a laptop, make sure the battery is charged and still plug it in.

Another possible unforeseen event is that eThe support you use for the installation fails for one reason or another in the middle of it (due to corruption of the unit, due to a failure that occurred during the installation) and you cannot install or use your computer half-installed to create another medium. In these cases, it is advisable to have another PC nearby... or a USB with a Linux distribution that you can use in 'live' mode.

Backup files and passwords

If you opt for a complete installation from scratch, you must first make sure that you have at least one backup copy of your files and passwords. Said copy must be kept on a removable storage unit or in a cloud service. (like OneDrive or Dropbox). Or, preferably, both.

Remember that you will be able to access most of the relevant files for an eventual backup by entering % HOMEPATH% in the address bar of your File Explorer.


As far as passwords are concerned, most browsers (such as Google Chrome) include, in their configuration section, a function of exporting passwords to a CSV file that will allow you to consult them even if the installation fails.

Yes, we know that these browsers also have a cloud saving function, and even synchronization with other devices, but the advantage of the resulting * .csv is that you can also use it to import passwords from another browser, in case you have decided to take advantage of the new installation to try something new.


Do not forget to save your product key

But if having documents and passwords on hand is important, there is other information contained in your current computer that is just as vital for a Windows installation; and, of course, you will need it many before. We are talking, of course, about the serial number of the operating system itself (if you are already using Windows 10) or paid software like MS Office, for example.

You don't have the original box with the serial number engraved on hand? No problem: there are several small applications that solve this for us. We recommend, for example, ProduKey by NirSoft, which does not require installation. Here are all the details on how to use it.

Collect software and drivers

If you are going to start an installation from scratch and you want to start working with your PC as soon as possible After that, collect and save all the installation files for the software you want to have on a USB drive.

In these cases it may be interesting to use Ninite, a customizable bulk installer of the most widely used free and freemium softwareor, and that we tell you how to use here.


Installable software catalog from Ninite.

Just in case, it doesn't hurt to have a complete list of the software installed on our current equipment, which we can create from the command line like this (customize in your case the creation path of the text file):

PARA CMD: wmic /output:D:ListaDeSoftware.txt product get name,version

PARA POWERSHELL: Get-ItemProperty HKLM:SoftwareWow6432NodeMicrosoftWindowsCurrentVersionUninstall* | Select-Object DisplayName, DisplayVersion, Publisher, InstallDate | Format-Table –AutoSize > D:ListaDeSoftware.txt

The same advice as that applied to software (download and compile) can be applied to hardware drivers, especially if you know that you have a device that Windows is not able to detect during installation or that does not work well with generic drivers.

Post-installation: Make a backup

Technically, this is not something to consider 'before' installing Windows 10 ... but if you do, you could avoid future installations: create an image of your system (a full backup) as soon as you finish installing it, before you start installing applications.
