What does EaseUS Key Finder do?

It scans an installed Windows PC and displays the product keys and serial numbers for Windows, Office, Adobe, SQL Server, and 10,000+ other programs. Alongside license keys, it reveals saved WiFi network passwords and the logins stored in Internet Explorer, Firefox, Chrome, and Edge. Everything found can be copied to a plain text file or saved as a PDF. The typical use case is capturing every key right before you reinstall Windows or move to a new machine, so nothing has to be repurchased.

Can EaseUS Key Finder find Microsoft 365 or Office 2019 keys?

No. Its Office key recovery is limited to Office 2003 through 2013 and the 2016 MSI installer, so it does not retrieve keys for Office 2019, 2021, 2024, or Microsoft 365. Modern Click-to-Run and 365 installs are linked to your Microsoft account rather than a local product key in the registry, which is why no finder tool can read them. Adobe coverage is similarly capped at CS2 through CS6 and does not include Creative Cloud apps. If you only need a 365 license, check your Microsoft account instead of this tool.

Does EaseUS Key Finder run on Mac?

No. EaseUS Key Finder is a Windows-only program supporting Windows 11, 10, 8.1, 8, 7, and Windows Server, with no macOS build available. Mac users cannot use it to recover keys from a Mac system. It can, however, read keys from a Windows Server installation, which many lightweight finders skip. Run it on a working Windows PC, including against a second Windows drive you have attached.

Can it recover keys from a PC that will not boot?

Yes. EaseUS Key Finder can scan product keys from a second, dead Windows installation or an unbootable HDD/SSD. Connect the old drive to a working Windows computer, point the tool at that offline system, and it pulls the Windows and software keys directly from it. This is the main reason to keep it on hand: after a crash you can rescue your licenses before reformatting or discarding the disk. Saving the results to PDF at that point gives you a permanent record for the rebuild.

What should users check before choosing EaseUS Key Finder?

Confirm the software you need is inside its supported scope: Windows and Windows Server, Office up to 2016 MSI, Adobe CS2–CS6, and the 10,000+ listed programs. It also surfaces WiFi and browser passwords and ships as a portable build that runs from a USB stick without installation. Note that the free trial only confirms keys exist on the system, while the full version is required to reveal and export the complete keys. If your licenses are all modern subscription products like Microsoft 365, a key finder of this type will have little to read.

Frequently asked questions about EaseUS Key Finder

Is EaseUS Key Finder available as a portable version?

Yes. A portable build is offered that runs from the executable without installation, so you can keep it on a USB stick and use it on different machines. This is handy for technicians who need to read keys off several PCs without leaving software behind.

Which web browsers can it recover saved passwords from?

It reads stored account names and passwords from Internet Explorer, Mozilla Firefox, Google Chrome, and Microsoft Edge. That covers the logins most Windows users accumulate over time, which is useful when migrating to a new browser profile or PC.

Can it back up my Windows account credentials?

Yes. It can back up account credentials and related app settings, then restore them on a new device. This helps avoid being locked out or having to recreate accounts after a system rebuild or hardware change.
