Windows 10 Pro: to extend the life of an older PC

Windows 10 Pro is a perpetual Windows license: pay once and use the system for life on 1 PC, with no subscription. It suits an older computer, or one that is not compatible with Windows 11, because it runs on modest hardware without a mandatory TPM 2.0 chip. A good fit to keep an existing machine going or to set up a secondary computer.

Your key arrives by email; you download Windows 10, install it and activate the license online in a few minutes. After activation, Windows stays tied to your device.

Support and updates: what you should know

Let us be clear: mainstream support for Windows 10 ended on 14 October 2025. The system still works fully, and Microsoft offers Extended Security Updates (ESU) for consumers until 13 October 2026. Enrolment is free by backing up your settings, or available with 1,000 Microsoft Rewards points, or for a one-time 30 $. If your PC supports Windows 11, that is the more future-proof option (see below).

What is it for?

Windows 10 Pro still makes sense in several situations:

  • Older PC or one not compatible with Windows 11 (no TPM 2.0).
  • Keeping an existing machine going without changing hardware.
  • Secondary or backup computer.
  • Compatibility with older software or peripherals already in place.

The tools of the Pro edition

Everything the Home edition offers, plus functions built for professionals and advanced users:

  • BitLocker: locks the disk contents through encryption, in case of loss or theft.
  • Remote Desktop (host): allows a connection to this machine from another computer.
  • Hyper-V: lets you run virtual machines on the same device.
  • Group Policy: fine-tunes how the system behaves.
  • Domain join: links the machine to a company directory.

Windows 10 or Windows 11?

Is your computer recent and TPM 2.0 compatible? Go for Windows 11 Pro instead, which stays supported the longest. On an older or incompatible machine, Windows 10 Pro keeps all its value. To compare, read our guide Windows 11 Pro vs Windows 10 Pro and check compatibility with Windows 11 minimum requirements and compatible PC.

Frequently Asked Questions

Does Windows 10 still receive security updates?
Mainstream support ended on 14 October 2025. Extended Security Updates (ESU) remain available for consumers until 13 October 2026: free by backing up your settings, with 1,000 Microsoft Rewards points, or for a one-time 30 $. Beyond that, moving to Windows 11 is best if your PC supports it.
What is the ESU program and how do I get it?
ESU (Extended Security Updates) provides critical security fixes after mainstream support ends, until 13 October 2026 for consumers. You enrol from Windows settings: free by turning on settings backup, through 1,000 Microsoft Rewards points, or for a one-time payment of 30 $.
Can my old PC run Windows 10 Pro?
Yes, in most cases. Windows 10 asks for modest specs (1 GHz, 2 GB of RAM on 64-bit, 32 GB of storage) and does not require a TPM 2.0 chip, unlike Windows 11. That is what makes it suitable for older computers.
Why choose Windows 10 over Windows 11?
Because your PC is older or not compatible with Windows 11 (no TPM 2.0), to extend an existing machine, for a secondary computer, or for compatibility with software and peripherals already in place. If your computer is compatible, Windows 11 is preferable over the long term.
What is the difference between Windows 10 Home and Pro?
The Pro edition adds BitLocker, Remote Desktop (host), Hyper-V, Group Policy and domain join. It is the edition suited to professionals, businesses and advanced users.
Is Windows 10 Pro a lifetime license?
Yes. It is a perpetual license: a single payment, no subscription, valid for the device where it is activated. Note that mainstream support ended in October 2025, with ESU available until October 2026.
On how many PCs can I use this license?
The license is valid for 1 PC at a time. To equip another computer you need an additional license.
How do delivery and activation work?
You receive the key by email (instant delivery), install Windows 10, then activate the license online in a few minutes. An invoice in your name is provided.
