How to Transfer Your Microsoft Office License to a New Computer (2026 Guide)

Getting a new computer? One of the first things you'll need is Microsoft Office. But before you buy a new license, check whether you can transfer your existing Office license to your new PC or Mac. This guide covers every scenario — from retail keys to Microsoft 365 subscriptions — so you don't waste money on a license you don't need.

Can You Transfer Your Office License? Quick Answer

It depends on your license type. Here's the quick breakdown:

License Type	Transferable?	How Many Devices?	What to Do
Retail (Product Key)	✅ Yes	1 PC (or as purchased)	Deactivate on old PC, activate on new PC
OEM (Pre-installed)	❌ No	1 PC (tied to hardware)	Buy a new license for new PC
Microsoft 365 Subscription	✅ Yes	Up to 5 devices	Sign in on new PC, deactivate old if needed
Volume License (MAK/KMS)	⚠️ Depends	Per agreement	Check your licensing agreement
3-Device Key	✅ Yes	3 PCs	Activate on new PC (if under limit)

Not sure what type you have? Open any Office app → File → Account. If it says "Microsoft 365" you have a subscription. If it says "Office 2021" or "Office 2024" with a product key, you likely have a retail license. If Office came pre-installed when you bought the PC, it's probably OEM. See our complete license types guide for details.

How to Transfer a Retail Office License (Step-by-Step)

Retail licenses (product keys you purchased separately) can be transferred to a new computer. Here's how:

Step 1: Deactivate Office on Your Old Computer

1. Open any Office app (Word, Excel, etc.)
2. Go to File → Account
3. Note your product key or Microsoft account linked to Office
4. Uninstall Office from the old computer: Settings → Apps → Microsoft Office → Uninstall

Step 2: Install Office on Your New Computer

1. Go to office.com/setup or account.microsoft.com
2. Sign in with the Microsoft account linked to your Office purchase
3. Click Install Office and download the installer
4. Run the installer and activate with your product key

Step 3: Activate on the New Computer

1. Open any Office app
2. If prompted, enter your 25-character product key
3. If activation fails, try phone activation: open Command Prompt as admin, run OSPP.VBS /ACT
4. For persistent errors, see our Office activation troubleshooting guide

How to Transfer Microsoft 365 (Easiest Method)

Microsoft 365 subscriptions are tied to your Microsoft account, not your hardware. Transferring is simple:

1. Sign in to Office on your new computer with your Microsoft account
2. Download Office from account.microsoft.com
3. If you've hit your device limit (5 devices for Family, 5 for Personal), go to account.microsoft.com → Devices → Sign out on the old device

Pro tip: If you have a Microsoft 365 Lifetime license (5 devices), you can install on up to 5 PCs/Macs simultaneously — no need to deactivate the old one unless you've maxed out.

What If You Can't Transfer? (OEM Licenses)

If Office came pre-installed on your old computer (common with Dell, HP, Lenovo laptops), it's an OEM license. These are permanently tied to the original hardware and cannot be transferred. Microsoft's licensing terms are clear on this.

Your options for the new computer:

• Best value: Office 2021 Professional Plus (3 devices) — $14.99 — covers this PC and your next two
• Latest features: Office 2024 Professional Plus (3 devices) — $24.99 — newest version with AI features
• Budget pick: Office 2019 Professional Plus (3 devices) — $19.99 — still works great for basic needs
• Subscription: Microsoft 365 Lifetime (5 devices) — $24.99 — ongoing updates, cloud storage

How to Check Your License Type

Before attempting a transfer, confirm what license you have:

Method 1: Check in Office

1. Open Word or Excel
2. Go to File → Account
3. Look under "Product Information":
   • "Microsoft 365" = Subscription (transferable)
   • "Office Professional Plus 2021" or similar = Likely retail (transferable)
   • "Office Home and Student" with no product key = Might be OEM (check below)

Method 2: Check via Command Prompt

1. Open Command Prompt as Administrator
2. Navigate to your Office installation folder:
   cd "C:\Program Files\Microsoft Office\Office16"
3. Run: cscript OSPP.VBS /dstatus
4. Look for the LICENSE NAME field — it will say "Retail" or "OEM" or "Volume"

Transferring Office to Mac (or Mac to PC)

Cross-platform transfers don't work for one-time purchase licenses. Office 2021/2024 for PC and Office for Mac are separate products with different license keys.

If you're switching from PC to Mac (or vice versa), you'll need a new license:

• PC to Mac: Your Windows Office key won't work on Mac. Get Office for Mac
• Mac to PC: Your Mac Office key won't work on Windows. Get Office for PC
• Both platforms: Microsoft 365 (5 devices) works on both PC and Mac

See our Office Mac vs Windows guide for detailed platform differences.

Multi-Device Keys: The Smart Alternative

If you frequently switch computers or have multiple PCs, consider a multi-device key instead of transferring a single-device license every time:

Product	Devices	Price	Best For
Office 2024 Pro Plus (3 Devices)	3 PCs	$24.99	Latest features, multiple PCs
Office 2021 Pro Plus (3 Devices)	3 PCs	$14.99	Best value, multiple PCs
Microsoft 365 Lifetime (5 Devices)	5 PCs/Macs	$24.99	Cross-platform, most devices
Windows 11 Pro (3 Devices)	3 PCs	$14.99	Need Windows too

With a 3-device key, you activate on your current PC and still have 2 activations left for future computers — no transfer needed.

Common Transfer Mistakes (and How to Avoid Them)

❌ Mistake 1: Buying a New License When You Don't Need One

Check your license type first. If you have a retail key or Microsoft 365, you can transfer for free.

❌ Mistake 2: Forgetting to Deactivate the Old PC

Single-device retail keys must be deactivated on the old PC before activating on the new one. If you've already recycled or sold the old PC, contact Microsoft Support to deactivate remotely.

❌ Mistake 3: Trying to Transfer an OEM License

OEM licenses are non-transferable. Don't waste time trying — buy a new key instead.

❌ Mistake 4: Buying the Wrong Platform (PC vs Mac)

Office for PC and Office for Mac use different license keys. Make sure you buy the right one for your new computer. See our Mac vs Windows guide.

FAQ

Can I transfer Office to more than one new computer?

With a single-device retail key, you can only have Office active on one PC at a time. But you can transfer it as many times as you want — there's no limit on the number of transfers, just the number of simultaneous activations. For multiple PCs, get a 3-device key.

Will I lose my Office files when I transfer?

No. Your documents (Word files, Excel spreadsheets, etc.) are separate from your Office installation. Copy them to your new computer via USB, cloud storage, or external drive. If you use OneDrive, they'll sync automatically.

My product key says it's already been used. What do I do?

This usually means Office is still activated on your old computer. Uninstall Office from the old PC, then try activating on the new one. If the old PC is gone, use Microsoft phone activation or see our activation error guide.

Can I transfer Office 2016 or 2019 to a new PC?

Yes, if it's a retail license. However, Office 2016 support ended in October 2025 and Office 2019 support ends in October 2025. Consider upgrading to Office 2021 ($14.99) or Office 2024 ($24.99) for continued security updates.

Is it cheaper to transfer or buy new?

Transferring is free. But if you can't transfer (OEM license) or want to upgrade, a new key from OfficeAndWin starts at just $14.99 for Office 2021 Pro Plus — far less than Microsoft's retail price.
