How to Upgrade Windows 7 to Windows 10: Complete Migration Guide

You can still upgrade Windows 7 to 10 in 2026 and keep the files and programs on it, but the free part is over: Windows 7 keys stopped activating Windows 10 in 2023, so you need a Windows 10 key. An old PC in the corner still runs Windows 7, waiting for the upgrade. Its owner swears it “just works”.

You run setup.exe from current installation media inside the old system, and choose to keep everything.

• Back up first, and confirm Service Pack 1.
• Get a Windows 10 key. Old Windows 7 keys won’t do.
• Build current installation media.
• Start setup inside Windows 7, keep files and apps.
• Afterwards: activation, drivers, a restore point.

What doesn’t work any more is the free part. Since September 2023, Windows 7 keys have stopped activating Windows 10. So you need a Windows 10 product key.

Running the old system online today is like driving around without insurance.

Plenty of old machines make the move this way. The newer system runs better on older hardware than people think.

There’s a learning curve, and for a week somebody asks where the Start menu went. Below is the whole route, with the 2026 catches older guides skip.

Can you still upgrade Windows 7 to 10 in 2026

Yes. Version 22H2 setup runs on Windows 7 Service Pack 1 and can keep your files and apps.

One thing changed, though. Windows 7 product keys don’t activate the newer system now.

For years a quiet loophole existed. Microsoft’s official free offer ended on July 29, 2016.

Windows 7 and 8 keys kept activating Windows 10 anyway. Microsoft closed that path in September 2023.

Machines activated before the cutoff stayed activated. Everything moved since then needs a real Windows 10 or Windows 11 license.

Windows 10 or Windows 11 for an old PC

If the PC meets the Windows 11 requirements, we’d take it to Windows 11.

Most PCs from the Windows 7 era fail those checks. For them, Windows 10 22H2 is the realistic step until a new PC.

Not sure where your PC stands? Our Windows 11 requirements guide lists each check.

A rule of thumb we’d go by: Intel chips older than 8th generation aren’t on Microsoft’s list. Neither are AMD chips older than Ryzen 2000.

Those make up most Windows 7 machines still in use.

Does the PC meet the requirements

Most PCs that shipped with Windows 7 do. In practice, 4 GB of RAM and an SSD make the difference between usable and painful.

Check your edition and bitness first. Click Start, right-click Computer and open Properties.

A 32-bit Windows 7 can only go in place to 32-bit Windows 10. Switching to 64-bit takes a clean install.

With 4 GB of RAM or more, 64-bit is worth that trade. A 32-bit system can’t use more than about 4 GB anyway.

Getting the old PC ready for the Windows 7 to 10 upgrade

Prep work is boring. Too many people wing it and end up with a computer in worse shape than before.

Twenty minutes of prep saves hours of fixing a half-finished setup.

Write down your Wi-Fi password and the login details for your email before you start. Afterwards the system may ask for both. Finding them on a half-configured PC is no fun.

The product key question

In almost every case you need a fresh key.

Since around September 20, 2023, Microsoft’s activation servers don’t accept Windows 7 or Windows 8 keys for the two newer systems.

Only PCs that were already moved and activated before then keep their digital license. Everyone else needs a genuine Windows 10 Home or Pro key.

Older guides said the free route still worked quietly. It did, for years. Not any more.

Your Windows 7 key still matters for your records. It shows which Windows 10 edition matches your old one.

If you have no clue where your old key is, don’t panic. Our guide on how to find a Windows product key helps. Free tools such as NirSoft’s ProduKey can read it from the current installation.

Some antivirus programs flag that tool, because it reads license data. We’d download it only from the author’s site.

And if the old Windows 7 isn’t genuine, nothing turns a non-genuine copy into a licensed system.

Just avoid the sketchy key sellers. Keys that cost almost nothing tend to stop working after a few weeks.

Need a key? HypestKey sells a genuine Windows 10 Home key and Windows 10 Pro key. Delivery is instant to email.

You can enter it during setup or afterwards in Settings.

Making the installation USB

Microsoft’s free Media Creation Tool downloads Windows 10 22H2 and makes the drive bootable. Everything already on the drive is erased.

• Get the Media Creation Tool from Microsoft’s Windows 10 download page. It’s free and comes straight from Microsoft.
• Plug in a USB drive with at least 8 GB. Move anything important off it first.
• Accept the license terms and pick “Create installation media for another PC”.
• Choose the language and architecture that match your Windows 7, 64-bit or 32-bit.
• Select the USB flash drive and let it download. That’s several gigabytes, so start before lunch.

If the tool refuses to start on the old machine, run it on any other Windows PC.

We’d take a 16 GB or 32 GB drive. They cost about the same, and extra room never hurts.

You’re working on the same machine, and the USB drive still pays off. It gives you a plan B if setup fails halfway.

Our guide to creating a bootable Windows 10 USB goes into more detail. It covers Rufus and drives that won’t boot.

How to upgrade Windows 7 to 10 and keep your files

There are two ways to start: from inside Windows 7, or by booting from the USB.

Booting from the USB only gives you a clean install, which wipes your programs. So start from inside Windows 7.

1. Plug in the laptop charger and the USB drive. Sign in to Windows 7 with an administrator account.
2. Open Computer, double-click the USB drive and run setup.exe. Click Yes in the User Account Control prompt.
3. When asked, choose to download updates, which makes setup smoother. Accept the license terms.
4. Enter your Windows 10 product key. The edition you get depends on the key, so a Pro key gives you Pro.
5. On “Choose what to keep”, pick Keep personal files and apps.
6. Click Install and wait. The PC restarts several times, and the screen can go black for a while.
7. Finish the setup screens: region, keyboard, account and privacy choices.

Unless the old system is badly broken, keep everything. That’s the whole point of the in-place route.

Now comes the waiting. Typically it’s one to three hours, and it can stretch to half a day.

It depends on the computer’s speed and on how much is installed. We’d start on a Saturday afternoon with nothing else going on.

Whatever happens, don’t turn the computer off while it’s working, even if it looks stuck. People panic and hit the power button, and that makes everything worse.

A greyed-out “Keep personal files and apps” tells you setup sees a mismatch. That’s the wrong language, the wrong bitness or no Service Pack 1. We’d fix the mismatch and not accept “Nothing”, which erases everything.

Where these steps apply

For a machine that stays on the old system, we still carry Windows 7 Home Premium keys.

After you upgrade Windows 7 to 10

If you made it this far, you should be looking at the Windows 10 desktop. Don’t celebrate yet.

Our Windows 10 activation guide covers the error codes.

A restore point is like a photo of the system while everything works. If something breaks down the road, you’ll be glad it’s there.

Getting used to the newer system

It feels familiar. The desktop, the taskbar and File Explorer work much the same.

It’s like moving from an old phone to a newer one. The basics work the same way, and there’s a bunch of fresh stuff to figure out.

Some people like the live tiles, and others find them annoying. The search is one of our favorite improvements.

When things go wrong

Even if you follow every step, setups sometimes go sideways. Most problems have straightforward fixes.

If setup fails, it usually rolls back to the old system by itself.

Every computer is different. Some sail through in under an hour, and others take most of the day.

Patience is the key. Don’t give up if the first attempt fails.

Your files and programs

After the in-place route, your documents, photos, music, desktop files and user accounts stay exactly where they were. Most programs stay too.

Settings and browser favorites carry over as well.

Both systems use the same NTFS file system, so nothing has to be converted.

Most programs will still be there and working, though some need an update. Really old programs occasionally have issues.

Microsoft has kept backward compatibility pretty good. In the worst case, compatibility mode usually sorts it out.

Only programs that don’t run on the newer system get removed. Setup lists them before it starts, so read that list.

Making the most of it

Once you’re there, use the features the old system never had.

Then plan the next step. If the PC passes the Windows 11 checks, an activated Windows 10 can move to Windows 11 for free.

If it doesn’t pass, start budgeting for a new machine.

The whole job looks like a huge pain on paper. Most of it is waiting for the computer to do its thing.

When you’re done, you have a more secure system that handles modern software and websites properly.

If you really hate something about the interface, there’s usually a way to switch it off.

The old computer gets a few more good years and doesn’t become a paperweight.

Common mistakes when you upgrade Windows 7 to 10

• Starting with no backup.
• Booting from the USB and wiping the programs by accident.
• Expecting the old Windows 7 key to activate the newer system.
• Accepting “Nothing” on the “Choose what to keep” screen.
• Pressing the power button because the screen looks stuck.
• Leaving a third-party antivirus on during setup.
• Deleting Windows.old before the 10 days are over.
• Buying a key that costs almost nothing from a sketchy seller.

Upgrade to Windows 10 from Windows 7 or 8.1 with the Media Creation Tool

Back up first. A USB drive with Documents, Desktop and browser bookmarks is enough for most homes.

1. Download the tool. From Microsoft’s Windows 10 download page, nowhere else.
2. Run it as administrator. Accept the license terms.
3. Choose “Upgrade this PC now”. Then wait while it downloads.
4. Enter the key when asked. Edition must match the key.
5. Pick what to keep. Files and apps, files only, or nothing.
6. Install. Several restarts. Leave the laptop plugged in.

On a Windows 7 PC, everything above this section is the detailed version. Coming from 8.1, we’d use the Windows 8 to 10 upgrade guide instead, same tool with the 8.1 quirks.

Prefer a USB stick? The same tool has “Create installation media for another PC”, which needs a blank 8 GB drive. Our guide to creating a bootable Windows 10 USB walks through it.

Already on Windows 10: get the newest version

Different tool. Same download page.

The Update Assistant sits at the top, with an “Update now” button. It moves an older Windows 10 build to version 22H2 in place. Files, apps and activation stay put.

Windows Update usually offers the same thing. We’d use the assistant only when Windows Update keeps stalling on an old build.

Leaving S mode on Windows 10

Some cheap laptops ship in S mode. Store apps only.

Switching out costs nothing, according to Microsoft’s S mode help page. One catch: it’s one-way. Once out, there’s no going back to S mode.

• Settings. Update & Security, then Activation.
• Find “Switch to Windows 10 Home” or the Pro version of that line. Tap “Go to the Store”.
• Press Get. A confirmation appears, done.

Careful with the neighbouring “Upgrade your edition” link. That’s a paid edition change, not the S mode switch.

Typical Windows 7 to 10 upgrade problems

Windows 7 key rejected at activation

Expected since 2023. Activation refuses Windows 7 and 8 keys for Windows 10 now. Settings, Update & Security, Activation. Change product key, type the Windows 10 key, Next.

Keep personal files and apps is greyed out

Usually no Service Pack 1. Or the USB has a different language or bitness than Windows 7. Install SP1 through Windows Update, rebuild the media to match, run setup.exe again.

Programs gone after setup from the USB

Booting from the stick gives you a clean install, so the programs are gone. Didn’t format the drive? Then the old user folders usually sit in Windows.old. Next time, start setup.exe from inside Windows 7.

Setup rolled back after a forced shutdown

Switch the PC off mid-setup and it undoes itself, back to Windows 7. Annoying, mostly harmless. Run it again and leave it alone, black screen or not.

Old printer silent after the upgrade

The Windows 7 driver is the usual suspect. Grab the Windows 10 driver from the manufacturer’s site. No such download? Windows Update often has a basic one.

Go back to Windows 7 is missing

The option lives 10 days, on the Recovery page. After that, or once Windows.old is deleted, it’s gone. Then only a clean Windows 7 install from your own media brings it back.

Not enough disk space for setup

Small drives hit this. Old installers and a pile of downloads are typical. Disk Cleanup, then the Downloads folder, until 32 GB are free.

8 GB of RAM on a 32-bit Windows 7

The in-place route stays 32-bit, and most of that RAM goes unused. For 64-bit, plan a clean install of Windows 10 and set the programs up again.

Setup stops with a third-party antivirus

Old security suites block setup without saying why. Uninstall the suite with its vendor’s removal tool, restart, run setup again. Microsoft Defender takes over afterwards.
