As we get closer to the Windows 10 end-of-life (EOL) date, I’m starting to get more specific questions about the complications of upgrading to Windows 11. The fringe cases are bubbling up, and it’s clear that some environments might not be able to make the switch without some hiccups. Generally, there are three main reasons why a computer can’t be upgraded to Windows 11:
Why I Can’t Upgrade to Windows 11
- The computer doesn’t have TPM 2.0. Microsoft requires a security feature called TPM 2.0 for Windows 11. It’s built into the processors of newer computers, but older devices may not have it.
- There isn’t enough disk space. You need at least 84GB of free space to perform the upgrade. In some cases, there’s just no way to free up that much space on an older machine.
- Peripheral or adapter compatibility. Some peripherals and adapters that worked fine on Windows 10 but won’t work on Windows 11.
What Are My Options?
The obvious recommendation is to upgrade to Windows 11. But in some cases, it just isn’t that simple. If that’s what you’re facing, here are four options to consider:
1. Ignore Windows 11 and Keep Running Windows 10 After EOL
Yes, Windows 10 will still work after the EOL date. It won’t suddenly shut down. If the computer is running one standard application and the Windows firewall is turned on and this computer doesn’t need to meet any compliance requirement, this this might be a reasonable option. It’s worth having a conversation about it.
2. Upgrade to Windows 11 Without TPM 2.0
Don’t believe everything you read online. Microsoft has been pretty consistent: you can install Windows 11 without TPM 2.0, but it’s not supported. This means it might work fine for a while, but there’s no guarantee it won’t stop receiving updates or that a future update won’t break the system entirely. If replacing your computer is really difficult, this might be an option—but it’s risky.
3. Install an After-Market TPM 2.0 Module
If your hardware doesn’t have TPM 2.0, you might be able to buy a module and install it yourself. These aren’t expensive, but they’re not exactly plug-and-play. Compatibility can be tricky. If you have 100 identical machines, it might be worth testing one module to see if it works before committing to a bulk purchase.
4. Buy Time with Windows Extended Security Updates
Microsoft offers Extended Security Updates (ESU) for Windows 10 after the EOL date. For under $75 per PC, you can get an extra year of security updates. Pricing is a little complicated and there are a few catches:
- You’ll need an Enterprise Agreement.
- You’ll need to find a reseller willing to sell you the licenses (and they’ll probably charge above list price).
- You only get security updates—no feature updates or support.
This option doesn’t solve the problem long-term, but it might help you meet compliance requirements or buy some time while you plan your next move.
The Bottom Line
Upgrading to Windows 11 is not a question of “if”, but of “when”. If waiting another year or 2 makes the difference for your budget then there are options.
