What should I do if there is an error code 0xc004e003 when win7 is activated?

Error code 0xc004e003 appears because it was activated by an alternative method. Please restore the tokens.dat file (C: \ Windows \ Service Profiles \ Network Service \ Appdata \ Roaming \ Microsoft \ Software Proton Platform) or reinstall the system. If it has been activated by an alternative method, an error code 0xc004e003 will be prompted when it is activated by OEM7.

You can try the following activation methods:

First, check whether the system activation key is attached to the bottom of the computer. If so, it can be activated. (The system version should correspond, otherwise it cannot be activated. )

Second, you can purchase the key of the corresponding version of the system from Microsoft official or other channels to activate it.

Third, search the corresponding version of the activation code or activate the activation tool online.
