Who needs to act, what happens if you stay put, and how to check your PC in five minutes
For about a year, staying on Windows 10 for gaming has been a "maybe later" decision. This month it turns into a "pretty soon" one. NVIDIA says its final Game Ready driver for Windows 10 ships in October 2026, and starting in November, new Game Ready and Studio drivers require Windows 11. At the same time, a couple of the season's biggest PC releases have started drawing the same line.
Nobody's PC is going to stop working next month, and we're not here to scare you into a new rig. But if you game on Windows 10, it's worth knowing exactly where you stand, whether your current machine can make the jump for free, and when a new build actually makes more sense. Here's the straight version.
WHAT ACTUALLY CHANGED
A handful of changes landed close together, and they add up to the end of Windows 10 as a first-class gaming platform:
| What | When | What it means |
|---|---|---|
| Windows 10 mainstream support ends | Oct 14, 2025 | No more regular updates; Microsoft's Extended Security Updates (ESU) program covers security fixes for those enrolled |
| Windows 11 version 26H2 released | Sept 29, 2026 | Generally available as a small enablement package for current Windows 11 PCs |
| The Witcher 3 Remastered | Sept 29, 2026 | Free upgrade that no longer supports Windows 10 |
| NVIDIA's final Game Ready driver for Windows 10 | October 2026 | From November, new Game Ready and Studio drivers require Windows 11 |
| Call of Duty: Modern Warfare 4 | Oct 23, 2026 | Requires TPM 2.0 and Secure Boot on PC |
The NVIDIA change is the big one for most gamers. Game Ready drivers are where day-one optimizations and fixes for new releases show up. Windows 10 doesn't get cut off completely: NVIDIA says it will keep shipping quarterly security-only driver updates for Windows 10 through October 2029. That keeps your system patched, but it won't bring the per-game tuning that new titles usually get at launch.
WHO NEEDS TO ACT (AND WHO DOESN'T)
- Already on Windows 11? You're fine. Keep Windows Update and your GPU driver current and you'll pick up 26H2 and every new Game Ready driver as normal.
- On Windows 10 and playing new releases? This is you. Once November drivers arrive, you'll be gaming on an older driver branch, and some new games simply won't install or launch.
- On Windows 10 and playing older favorites? You have more breathing room. Your library doesn't stop working, and security-only driver updates continue. Still, plan your move rather than waiting for a game you want to force it.
- Competitive multiplayer players: pay attention to the TPM 2.0 and Secure Boot requirement. It's tied to anti-cheat, and it's a hardware and firmware check, not just an OS version check.
WHAT HAPPENS IF YOU STAY ON WINDOWS 10
Short term, honestly, not much. Your games keep running, your current driver keeps working, and you'll still get security-only driver updates from NVIDIA. If you've enrolled in Microsoft's ESU program, you'll keep getting OS security fixes for as long as your coverage lasts.
The cost shows up over time. New games launch with optimizations aimed at the Windows 11 driver branch. Bug fixes for a stuttering new release land in a Game Ready driver you can't install. And as more publishers follow The Witcher 3 Remastered and Modern Warfare 4, the list of games you can't run at all will grow. Windows 10 becomes a machine for the games you already own, not the ones coming out.
DON'T CONFUSE THE TWO KINDS OF UPDATES
Security-only driver updates keep a Windows 10 system safe to use. They are not the same as Game Ready drivers, which carry the performance work and fixes for new releases. Through 2029 you get the first kind on Windows 10, not the second.
HOW TO CHECK IF YOUR PC CAN RUN WINDOWS 11
Windows 11's big hardware gates are TPM 2.0, Secure Boot (UEFI firmware rather than legacy BIOS), and a processor on Microsoft's supported list. Most gaming PCs from the last several years clear all three, but plenty ship with TPM or Secure Boot switched off in the firmware. Here's how to check, quickest first:
- PC Health Check. Microsoft's free PC Health Check app runs the official Windows 11 compatibility check and tells you which requirement, if any, you're missing.
- TPM: run
tpm.msc. Press Win + R, typetpm.msc, and hit Enter. Under TPM Manufacturer Information, look for Specification Version: 2.0. If it says no compatible TPM was found, it may just be disabled in the BIOS (look for AMD fTPM or Intel PTT / Platform Trust Technology). - Secure Boot: run
msinfo32. Press Win + R, typemsinfo32, and check the System Summary. You want BIOS Mode: UEFI and Secure Boot State: On. "Unsupported" or "Legacy" means a firmware setting needs changing, and on older installs the drive may need converting to GPT first.
A word of caution: flipping firmware settings and converting drives is very doable, but back up first. If you're not comfortable in the BIOS, that's a fine time to ask for help rather than guess.
UPGRADE OR NEW BUILD?
UPGRADE THE OS IF…
PC Health Check gives you a pass (or only flags TPM or Secure Boot being turned off), your GPU still handles the games you play at the settings you want, and you're happy with the rig otherwise. The Windows 11 upgrade is the cheapest fix here, and a good machine on the current OS has plenty of life left.
CONSIDER A NEW BUILD IF…
Your CPU isn't on the supported list, your board has no TPM 2.0 option, or you were already eyeing an upgrade because new games are pushing your GPU. In those cases you'd be spending time and money keeping an older platform alive just to run into the next wall. Starting fresh on a current platform clears the OS question and the performance question in one move.

BOTTOM LINE
If your PC passes the Windows 11 check, upgrade the OS and keep gaming. That's the honest answer, and for a lot of folks it costs nothing but an afternoon. If it doesn't pass, you don't need to panic: Windows 10 keeps running and gets security-only driver updates through October 2029. But new games and new drivers have moved on, and they won't be coming back.
For anyone shopping for a new rig anyway, this one's simple. Every Lone Star True Custom Rig comes with Windows 11 Pro pre-installed and ready to game, so TPM, Secure Boot and driver support are handled before it leaves our shop. Whether that's the Outlaw, the Wrangler, the Maverick or something you spec yourself in the Custom Builder, you'll be on the platform new games and drivers are built for.
SKIP THE UPGRADE HEADACHE
Every Lone Star rig ships with Windows 11 Pro pre-installed, optimized and ready to game. See what's included, or spec your own build part by part.
