Saving the activation token (digital license) allows you to quickly restore the legal status of the system after reinstallation without re-entering the key. The backup includes the files ‘tokens.dat’, ‘pkeyconfig.xrm-ms’ and the folder data ‘System32\Spp’. It is easy to get the hardware link back from it if the disk is changed or a clean install is required.
Built-in SLMGR tool
The slmgr command ‘slmgr.vbs’ is already in the system. Running as an administrator with the ‘/dlv’ parameter shows the license ID, and the combination of ‘/upk’ and ‘/cpky’ prepares the token for saving. Copy the mentioned files to an external storage medium – this is a basic but reliable way to create a backup.
Using ProduKey
NirSoft’s ProduKey reads the registry and extracts the ProductID for Windows 10 and 11. In the ‘Save Selected Items’ menu, select the ‘.txt’ or ‘.csv’ format and save the file to the cloud. The program does not change the license, but only records the data, so it is safe for corporate PCs.
Backup via KMSpico
Although KMSpico is known as offline KMS, it has a ‘Tokens Backup’ module. After launching, select the ‘Backup’ tab, click ‘Create’ – the utility auto‑saves the necessary files to the ‘KMSpico\backup’ subfolder. You can transfer this archive to USB or OneDrive and restore it with the same module when installing Windows again. The function works with a digital license and with OEM keys, without performing any illegal activations.
Trusted OPA Backup Option
OPA Backup scans the Software Protection Platform service, archives the tokens, and creates an automatic recovery script. Run it, specify the save directory and wait for the message ‘Backup completed successfully’. The resulting ‘.opa’ file remains applicable even after a major Windows11 update.
Conclusion: where and how to store backups
Make at least two copies: a local one on an encrypted USB flash drive and a cloud one (for example, OneDrive Personal Vault) – this reduces the risk of loss. Rename the files by adding the creation date and write down the Windows version to avoid confusion. Update your backup regularly for major upgrades or equipment replacements, and protect access to media with two-factor authentication. This way, a digital license will always be at hand without unnecessary hassle.
