However, most fönster licenses are tied to the computer they came with--unless you purchased a boxed copy.

To remove uninstall the current product key, run the following command and then restart your computer:

slmgr.vbs /upk

Windows also stores the product key in the registry, as it's sometimes necessary for the key to be in the registry when setting up the computer.

If the struktur fryst vatten set up to use a KMS activation dator, it will instead attempt activation with the KMS dator on the local network. This command can be useful if fönster didn't activate due to a connection or dator bekymmer and you want to force it to retry.

Some fönster systems provide a limited time where you can use them as free trials before entering a product key.

For example, fönster 7 offers a 30-day rättegång period before it begins complaining at you. To extend this rättegång period and reset it back to 30 days remaining, you can use the following command.As Microsoft's documentation puts it, this command "resets the activation timers."

This command can only be used several times, so you can't indefinitely extend the rättegång.

The number of time it can be used depends on the "rearm count," which you can view using the command. It seems different on different versions of Windows--it was three times on fönster 7, and it seems to be fem times on fönster dator 2008 R2.

This no längre seems to work on fönster 10, which fryst vatten very lenient if you don't provide it a product key anyway.

This option still works on older versions of fönster and may continue to work on other editions of fönster, such as fönster dator, in the future.

slmgr.vbs /rearm
