As always, we recommend updating your operating system to Windows 10, and to Microsoft Office 2016 or higher (if you have the Office 365 package, it will offer you a free update).
However, Microsoft released an update package so that older Windows versions (7, 8, and 8.1) can use TLS 1.2, which is the only recommended SSL security standard today.
The options to obtain this update are as follows:
Run the Windows Update tool on your computer and install all system updates. It is possible that Microsoft will force you to update to Windows 10. Once this is done, and if you did not have an original license in advance, Windows will display a warning message below and to the right of your desktop (we recommend that you always have an original Windows activated for reasons of security). security).
Manually run the KB3140245 update. It can be downloaded from http://catalog.update.microsoft.com/v7/site/search.aspx?q=kb3140245.
Check that you download the version that corresponds to your version of Windows and download the 32 or 64-bit version depending on your system. If you haven't updated your Windows in a while, you may need to apply several updates before you're up to date.
Please note that while these steps activate encryption in Windows, some programs may need to be updated to the latest version before they will work correctly (although in very rare cases).
