Computers (windows Xp) cannot install Android drivers (Android phones). The solution is as follows:

First of all, the official driver fully supports win XP, which can also be said to be compatible with mobile phone drivers, but the problem lies in the driver installation mechanism of win XP, which is not allowed without digital signature, so it needs to be closed.

Enter the system, [Win]+[C] bring up the charm menu-change computer settings-settings-general-restart advanced startup immediately-troubleshooting-advanced options-startup settings-restart, and then disable driver forced signature. If your friend's computer is activated on 180 days, the above steps are different. [Win]+[C] Bring up the charm menu-change computer settings-update and restore-restore-restart immediately under advanced startup, then troubleshoot-advanced options-startup settings-restart, and then disable driver forced signature.

In this way, we have solved the problem of driver signature. After re-entering the system, right-click the computer to enter management, then enter services and application services to find the equipment installation service, double-click to enter, and the startup type will be changed to automatic. In the service status, click Start and Apply.

Please make sure that the device installation service service is turned on, because you need to run win XP even if the display is automatic. At this time, drivers such as various mobile assistants can be updated, and drivers can be installed normally.
