Microsoft extended the Windows 10 Extra Security Updates program for one more year, putting the new free-coverage deadline at October 2027. That buys breathing room, not a reprieve. If you’re on the holdout side of the Windows 10 user base and the ESU window is your migration plan, you’ll need tooling that handles unsupported hardware, drive cloning, and the upgrade itself. We tested eight apps for upgrading from Windows 10 to Windows 11 in 2026.
The benchmark for each: how it handles TPM and Secure Boot bypasses, what it does for unsupported CPUs, and whether it leaves your data intact through the upgrade.
What to look for in a Windows 11 upgrade tool
A handful of criteria separate the tools that survive an upgrade gone wrong from the ones that brick a Friday afternoon:
- Eligibility check before the upgrade. Knowing what Microsoft objects to is half the battle.
- TPM 2.0 and Secure Boot bypass options. Microsoft enforces both on the supported path; bypass tools are the workaround for older but capable hardware.
- Driver compatibility coverage. The 11 upgrade fails on missing drivers more than on hardware checks.
- Drive cloning and migration. Some upgrades go cleaner as a fresh install on a new SSD with apps migrated across.
- Bootable USB creation. ISO mounting is fine for in-place; bootable USB is the safety net.
- Rollback plan. Windows 11 holds a recovery window of 10 days post-upgrade. Real backups extend it.
Quick comparison
| App | Best for | Free | Bypass support | Bootable USB |
|---|---|---|---|---|
| Rufus | TPM and Secure Boot bypass | Yes | Yes | Yes |
| WhyNotWin11 | Eligibility check + fix list | Yes | Diagnostic only | No |
| AveYo Universal MediaCreationTool | Scripted unsupported upgrade | Yes | Yes | Yes |
| PC Health Check | Microsoft’s eligibility tool | Yes | No | No |
| Windows 11 Installation Assistant | Microsoft’s official upgrade | Yes | No | No |
| Macrium Reflect | Pre-upgrade disk image | Limited | n/a | Yes (rescue) |

| Ventoy | Multi-ISO USB | Yes | n/a | Yes |
The 8 best apps for upgrading from Windows 10 to Windows 11
1. Rufus — best TPM and Secure Boot bypass
Rufus is the open-source USB creator that has the cleanest Windows 11 bypass workflow. Build the install USB, tick the boxes to remove TPM 2.0, Secure Boot, and 8 GB RAM requirements, and add a local-account option to skip the mandatory Microsoft account. The resulting USB performs both fresh installs and in-place upgrades on unsupported hardware.
Where it falls short: It’s a USB creator, not a guided upgrade tool. You still need the Windows 11 ISO. Updates over time may move the bypass mechanics.
Pricing:
- Free: yes, GPL
- Paid: none
Platforms: Windows 7+ build environment; targets Windows 10/11 installs
Download: Rufus
Bottom line: Pick Rufus when your hardware is technically unsupported and you want a clean install USB that ignores Microsoft’s modern requirements.
2. WhyNotWin11 — eligibility check with a real fix list
WhyNotWin11 is the third-party PC Health Check replacement that explains which requirement your machine fails and what would fix it. CPU, TPM, Secure Boot, RAM, disk type, partition style, all broken out item by item. Open source and frequently updated.
Where it falls short: Diagnostic only. It doesn’t perform the upgrade or the bypass; pair it with Rufus or AveYo.
Pricing:
- Free: yes, GPL
- Paid: none
Platforms: Windows 10
Download: WhyNotWin11 on GitHub
Bottom line: Pick WhyNotWin11 as the first tool you run before deciding which upgrade path to take.
3. AveYo Universal MediaCreationTool — scripted unsupported upgrade
AveYo’s MediaCreationTool.bat is a PowerShell wrapper around Microsoft’s own Media Creation Tool that adds bypass switches for unsupported CPUs. It can produce an ISO, a USB, or perform an in-place upgrade. The community keeps it updated as Microsoft tightens checks.
Where it falls short: Scripts from GitHub require trust in the maintainer; review the source if that matters to you. Some antivirus engines flag the registry edits.
Pricing:
- Free: yes, GPL
- Paid: none
Platforms: Windows 10, 11
Download: MediaCreationTool.bat on GitHub
Bottom line: Pick AveYo when you want an in-place upgrade on unsupported hardware and you trust an open-source script.
4. PC Health Check — Microsoft’s eligibility tool
PC Health Check is Microsoft’s official eligibility checker. It tells you yes or no on Windows 11 and lists the failing requirement. The output is less granular than WhyNotWin11 but it’s the reference Microsoft will quote at you if a support call comes up.
Where it falls short: It tells you “compatible CPU is required” without offering a fix or workaround. The diagnostic is shallow.
Pricing:
- Free: yes
- Paid: none
Platforms: Windows 10
Download: PC Health Check via Microsoft
Bottom line: Pick PC Health Check as the Microsoft-sanctioned baseline before running WhyNotWin11.
5. Windows 11 Installation Assistant — Microsoft’s official upgrade
Windows 11 Installation Assistant is the Microsoft-blessed in-place upgrade tool for supported hardware. Click through the prompts and your Windows 10 install becomes Windows 11 with apps and files retained.
Where it falls short: Refuses on unsupported hardware. No bypass options.
Pricing:
- Free: yes
- Paid: none
Platforms: Windows 10
Download: Windows 11 download page
Bottom line: Pick the official assistant if your hardware passes the check. There’s no benefit to bypass tools when you don’t need them.
6. Macrium Reflect — pre-upgrade disk image
Macrium Reflect is the safety net. Image your Windows 10 install to an external disk before you upgrade. If the upgrade fails or you hate Windows 11 after a week, restore the image and you’re back where you started.
Where it falls short: Macrium Reflect Free ended in 2024 and Macrium X is paid. Free third-party alternatives like AOMEI Backupper or EaseUS Todo Backup do the same job.
Pricing:
- Free: legacy 8.x only
- Paid: Macrium X from $75/year
Platforms: Windows 10, 11
Download: Macrium X
Bottom line: Pick Macrium (or one of the free alternatives in our Windows PC backup guide) before clicking Upgrade.
7. Laplink PCmover — apps and settings migration
Laplink PCmover is the apps-and-settings migration tool Microsoft used to bundle. If you’re upgrading to a new machine rather than upgrading in place, PCmover transfers installed apps, settings, and user profiles over the network. Microsoft’s own profile transfer story stops at OneDrive folders.
Where it falls short: Paid only. Some applications don’t transfer cleanly (anything tied to hardware GUIDs or system-level drivers). Slow on large user folders.
Pricing:
- Free: trial
- Paid: PCmover Express $29.95 one-time, Professional $59.95 one-time
Platforms: Windows 10 source, Windows 11 destination
Download: Laplink PCmover
Bottom line: Pick PCmover when the move is to a new machine and you want apps to travel.
8. Ventoy — multi-ISO USB stick
Ventoy turns one USB into a boot menu for every Windows ISO you’ve collected. Drop the Windows 11 ISO onto the Ventoy partition and it appears in the boot menu next to Windows 10, Linux distros, and any rescue tool you keep handy.
Where it falls short: Doesn’t bypass Microsoft’s hardware requirements by itself. Pair with Rufus or AveYo for that. Some firmwares need a Secure Boot exception for Ventoy itself.
Pricing:
- Free: yes, GPL
- Paid: none
Platforms: Windows, Linux, macOS
Download: Ventoy
Bottom line: Pick Ventoy when you swap between multiple ISO images often and a single USB beats juggling sticks.
How to pick the right one
If your hardware passes the Microsoft check, use PC Health Check, image with Macrium, then run the Installation Assistant. That’s the path of least resistance.
If your hardware fails on TPM or Secure Boot, run WhyNotWin11 to see the specifics, then Rufus to build a bypass USB.
If you want an in-place upgrade on unsupported hardware without juggling tools, AveYo’s MediaCreationTool.bat is the closest one-tool answer.
If you’re moving to a new machine, PCmover travels apps and settings the way Microsoft Account migration doesn’t.
If you keep a toolbox USB on your keyring, Ventoy is what holds it together.
Whichever path you take, image the source drive first. The October 2027 cliff is far enough out to plan; it’s also far enough that “I’ll think about it next year” turns into “I’m out of time” faster than expected.
