If you're considering upgrading to Windows 11, before you do anything, it's a good idea to take a moment and carefully review your existing computer. A thorough hardware checklist before upgrading to Windows 11 can save you a lot of headaches, error messages, and, most importantly, unnecessary purchases.
Although Microsoft has tried to simplify the process, the reality is that Windows 11's requirements are more restrictive than those of previous versions like Windows 10, 8, or 7. Here you'll find a complete guide, in Spanish (Spain) and written as clearly as possible, with everything you need to check: processor, motherboard, TPM, Secure Boot, memory, storage, graphics card, peripherals, and even what to do if your PC doesn't pass the test.
Why Windows 11 is more demanding on hardware
Windows 11 is not simply “Windows 10 with a fresh coat of paint.” Microsoft has positioned it as a platform focused on three pillars: reliability, security, and compatibility . This explains why it has raised the bar in several key components.
In terms of reliability , Microsoft's goal is to reduce crashes, blue screens, and other unusual problems often caused by outdated hardware or poorly optimized drivers. Requiring a minimum processor, firmware, and graphics card specifications allows for more thorough testing and ensures more stable performance.
The second pillar is security . Windows 11 relies heavily on technologies such as Secure Boot, the Trusted Platform Module (TPM), and modern encryption. All of this requires a hardware base that isn't always present in older computers, especially consumer-grade machines that are more than 8-9 years old.
Finally, there's compatibility . It might sound strange, but by defining which processors and minimum functions are accepted, Microsoft can ensure that new features (Copilot, DirectStorage, graphics improvements, etc.) work as intended and aren't degraded by having to support outdated architectures.
Official minimum hardware requirements for Windows 11
Before reaching for your wallet, the first thing to do is to familiarize yourself with the official Windows 11 requirements . These apply to both physical PCs and virtual machines that meet Microsoft's standards.
- Processor (CPU): 64-bit chip, 1 GHz or more, with 2 or more cores, and listed on Microsoft's list of compatible processors.
- RAMMinimum 4 GB.
- Storage: At least 64 GB of main drive (HDD or SSD).
- Graphic card: Compatible with DirectX 12 or later and WDDM 2.0 driver.
- Firmware: UEFI system that supports Secure Boot.
- TPMVersion 2.0 (physical module or TPM by firmware, fTPM).
- Screen: Monitor of at least 9 inches with HD resolution (720p or higher).
- Connectivity: Internet connection required during initial setup, especially in Home editions.
- Windows versionTo upgrade from Windows 10, at least version 2004 (and, in some manufacturers, 21H1) is required as a starting point.
Beyond these minimum requirements, there are advanced features that demand a higher level of hardware. Copilot and the more powerful AI functions , for example, require specific processors (such as some Snapdragon X Plus/X Elite SoCs in Copilot+ PCs), 16 GB of DDR5 or LPDDR5 RAM, and fast SSDs of at least 256 GB.
Hardware checklist: what to check piece by piece
With the requirements clear, it's time to get down to business. The most sensible way to prepare for the upgrade is to follow a hardware checklist , reviewing each important PC component and deciding whether it can be reused, upgraded, or if it's best to simply replace the entire system.
1. Processor (CPU): Power is not always synonymous with compatibility
The first filter is usually the processor. Windows 11 not only requires 64-bit architecture and multiple cores , but also that the model be on an official list. This excludes CPUs that, in terms of raw performance, are still perfectly adequate, but which Microsoft doesn't want to support due to their age or lack of certain extensions.
In practice, this means that many 3rd, 4th, or even 5th generation Intel Core processors, and their AMD equivalents, are not on the list . Although they can easily run Windows 11, the installer will block the standard upgrade if it detects that the model is not compatible according to Microsoft.
If you're in this situation and your computer is a few years old, you might consider something similar to what any user who built their PC back in the day would do: replace the motherboard and processor , keeping the SSD, RAM (if compatible), case, power supply, and peripherals. In many cases, with a moderate budget, you can make a huge leap in performance and compatibility with Windows 11.
2. Motherboard and firmware: UEFI and Secure Boot
The motherboard dictates key aspects such as the BIOS /UEFI type and TPM support. Windows 11 requires UEFI firmware with Secure Boot , a feature that verifies the booting system is signed and trusted, preventing malware and suspicious bootloaders from infiltrating the system.
On relatively modern motherboards, the support is usually there, but Secure Boot is often disabled by default. You'll need to access the UEFI settings (what we used to call "the BIOS") and locate the Secure Boot options to enable it.
If your motherboard only has a Legacy BIOS or doesn't fully support UEFI, your options are limited. Microsoft doesn't officially support Windows 11 installations without UEFI and Secure Boot, so if you want to go the "official" route, you'll have to replace your motherboard.
3. TPM 2.0: The security chip everyone is talking about
One of the most controversial aspects of Windows 11 is the TPM 2.0 requirement . The Trusted Platform Module is a chip (or a block of firmware) dedicated to security tasks: generating and storing cryptographic keys, authentication, disk encryption, protecting system integrity, etc.
It's been almost standard on business computers for many years, but on older home computers it's not always present or enabled . Here are several possible scenarios:
- The motherboard has a physical connector for a dedicated TPM 2.0 module, which you can buy separately and install.
- The board includes TPM via firmware (fTPM, PTT, etc.) but it comes disabled and must be activated in UEFI.
- The motherboard is so old that it does not support TPM 2.0 in any way, in which case you would be outside the official requirements.
Enabling the TPM via firmware is usually as simple as entering the UEFI settings and looking for an option like fTPM, PTT, Security Device , or something similar, and changing it to Enabled. Once enabled, Windows will detect it and allow you to continue with the installation if the rest of the hardware is compatible.
4. RAM and storage: minimums… and realistic recommendations
Regarding memory and disk, the 4 GB of RAM and 64 GB of storage that Microsoft requires are, frankly, the absolute minimum to be able to boot the system , but not a recommended configuration for working comfortably.
For normal office use, browsing, and light multitasking, it's highly advisable to go up to at least 8 GB of RAM , and if you're going to have many tabs, lightweight virtual machines, or heavy programs, aiming for 16 GB is a much more sensible bet.
Regarding storage, Windows 11 and its updates take up a significant portion of the disk. A 64GB SSD fills up almost immediately, so ideally, you should install Windows 11 on an SSD of at least 128GB , and even better if it's 256GB or larger. SATA SSDs remain inexpensive and represent a significant improvement over mechanical hard drives.
5. Graphics and DirectX 12: it doesn't just matter for gaming
Another point that often goes unnoticed is the graphics card. Windows 11 requires a GPU compatible with DirectX 12 and a WDDM 2.0 driver . In many modern CPUs, the integrated graphics card meets these requirements without issue.
The problem arises with systems that have very old integrated graphics or outdated dedicated cards that don't support DirectX 12. These systems might be able to run the desktop without major issues, but they aren't officially supported. In the context of this checklist, it's advisable to verify the exact GPU model and its DX12 compatibility.
Additionally, some new features, such as certain game optimizations or advanced multimedia functions, rely on modern APIs and recent drivers . If your graphics card is out of its lifecycle and doesn't receive drivers for Windows 11, you might encounter limitations or errors.
6. Screen, network and other recommended peripherals
The official screen requirement is quite modest: a panel of at least 9 inches with HD resolution . Virtually any monitor will pass this test, so there's usually no problem there.
Where it is worth paying attention is to the devices that best take advantage of modern features: decent webcams and microphones for video calls, quality speakers or headphones, IR cameras or biometric sensors for Windows Hello, Wi-Fi 6E connectivity if you want the latest in wireless networks, and even HDR support or high refresh rate screens if you are going to consume multimedia content or play games.
All of this is not mandatory to install Windows 11, but it is part of the recommended requirements if you want to take advantage of the system's new features and current applications that rely much more on online collaboration and hybrid work.
How to automatically check if your PC is eligible
If you don't feel like checking each component individually, Microsoft offers a dedicated tool to simplify things. The "PC Health Checker" application analyzes your computer's hardware and tells you if you meet the official Windows 11 requirements.
This utility ( WindowsPCHealthCheckSetup ) is very easy to use: you install it, run it, and after a quick scan, it tells you if the computer is compatible, what points are failing (CPU, TPM, secure boot, etc.) and, in some cases, gives clues on how to fix it.
Additionally, you can also use Windows Update directly from within Windows 10 to assess eligibility . By going to Start > Settings > Update & Security > Windows Update, many machines will display a notification indicating whether the computer can be upgraded to Windows 11 or if it doesn't meet the requirements.
If you prefer third-party options, there's free and open-source software like WhyNotWin11.exe that provides a highly visual diagnostic, highlighting each requirement in green or red. It's a quick way to pinpoint the specific bottleneck.
Manufacturer support and Windows 10 limitations
Another important point on the checklist is medium-term support. Even if you manage to install Windows 11, you'll need drivers, BIOS/UEFI updates, and firmware to keep everything running smoothly. This is where manufacturers like Dell, HP, Lenovo, and others come in.
For example, Dell explicitly states which models it officially supports with Windows 11. For computers that don't meet the upgrade requirements, they continue to offer support for Windows 10 until the end of its lifecycle, but they don't provide drivers or official support for Windows 11 on those machines.
Also keep in mind that if your PC doesn't meet the minimum requirements, manufacturers don't usually offer Windows 11 drivers for that model. Something might work through Windows Update, but you'll be outside the "supported path" and could encounter devices that don't perform well or stop working after a major update.
Recommended steps before upgrading to Windows 11
If your PC passes the hardware checklist or you've decided to upgrade to meet the requirements, it's advisable to follow a few steps before the upgrade to minimize risks. Ideally, you should prepare well in advance and not improvise on the day of the upgrade.
First, back up your important files . Although upgrading from Windows 10 to Windows 11 is designed to preserve documents, settings, and applications, any process of this kind carries a minimal risk. A backup to an external hard drive, NAS, or the cloud (OneDrive, Google Drive, etc.) is essential.
It's also a good idea to make sure your current Windows 10 installation is updated to a recent version (at least 2004, and in many cases 21H1 or later). This speeds up the Windows Update process and includes patches that prevent problems during the upgrade.
When Windows Update detects that your computer meets the requirements, you'll see an option to download and install Windows 11 from Settings > Update & Security > Windows Update > Check for updates. Once the installer is downloaded, simply follow the instructions and choose the "Upgrade" installation type to keep your data.
During installation, you may see a warning indicating that certain components do not fully meet the recommended requirements. On officially supported systems, this should not block the process , although it's advisable to carefully read the messages before accepting and continuing.
What if your PC doesn't meet the requirements: options and risks
The official theory states that if your PC doesn't meet the minimum requirements, you can't install or upgrade to Windows 11. In practice, however, it's more flexible. Microsoft has adopted a pragmatic approach: it knows it can't control every aspect of the ecosystem and has left the door open for installations on unsupported hardware, albeit without guarantees.
In fact, official documentation exists explaining how to install or update Windows 11 on unsupported devices . However, it clearly warns of the consequences: potential compatibility issues, features that may not function as intended, lack of technical support, and an uncertain future regarding updates.
Over the past few years, third-party tools and methods have emerged that allow users to bypass system requirements checks , either during the upgrade phase or by installing directly from a modified bootable medium. Pre-made images designed to circumvent these restrictions are even circulating on P2P networks, with the added security risks that this entails.
If you value stability and official support, it's wisest to view these methods as temporary or trial solutions, not as the foundation for a computer you intend to use daily for work or studies. In an emergency, they might get you out of a bind, but in the medium term, it's advisable to use hardware that meets the Windows 11 checklist.
Changes in functions and features when upgrading to Windows 11
The hardware checklist not only helps you know if your PC will hold up, it also helps you anticipate which Windows 10 features will disappear or change in Windows 11 and how they might affect your daily life.
Among the most striking changes is the new Start menu. The design has been completely revamped, removing features like Live Tiles and the ability to resize the Start panel as in Windows 10. The taskbar has also been significantly redesigned. It can no longer be positioned at the top or side of the screen.
Other features that have changed, been merged, or have been completely removed include:
- Snipping Tool and Snipping and SketchThey are now integrated into a single application under the name "Snipping Tool".
- Mathematical input panelIt has been removed, although the math recognizer is installed on request when needed.
- Tablet mode: disappears as such and is replaced by new behaviors when docking or undocking keyboards.
- Timeline (Timeline): has been withdrawn.
- Quick status on the lock screenIt is no longer available.
- News and interestsThe old taskbar function is transformed into the Widgets panel.
- WalletThis feature has been removed from the system.
It's a good idea to carefully review these differences before upgrading, especially if you rely heavily on specific Windows 10 features. Knowing what's being removed and what's being replaced will prevent surprises once Windows 11 is installed.
A good hardware and features checklist lets you clearly know where you stand: whether your current PC only needs minor adjustments, whether it's more worthwhile to upgrade the motherboard and processor while reusing the rest, or whether it's time to change your computer and enjoy Windows 11 with all its advantages , minimizing headaches and avoiding getting stuck when Windows 10 stops receiving support.
