Windows XP reinstallation does not require reactivation
if you need to reinstall Windows XP, you usually have to reactivate it. In fact, as long as the Windows\ System32\Wpa.dbl file is backed up during the first activation, after reinstalling Windows XP, it is only necessary to copy the file to Windows\System32, so there is no need to activate it.
If you don't know whether your Windows XP is activated, you can check it in this way: click Start → Run, and enter: oobe/msoobe /a a. After entering the car, the system will pop up to tell you whether the system is activated.
Windows XP disables driver digital signature warning
Because Windows XP uses digital signature in the driver, sometimes the driver can't be installed. You can ignore the digital signature function in the following ways, open Control Panel → Performance and Maintenance → System, select the Hardware tab in the pop-up system properties window, click the Driver Signature button, and select Ignore in the pop-up window.
