I uninstalled it from Control Panel Programs and Features but there still a driver called AiCharger.sys exist and running in my PC. AiCharger.sys file located at C:\Windows\SysWOW64\drivers , when I disable the driver startup, All the USB ports on the PC stops working after the restart.
Hello @aussiekendoll,
It sounds like thatDriverhas a dual purpose [USB Ports]. Therefore, if your OS is running OK with it installed, I would leave it installed!
I hope this helps.
No my OS does not sleep,hibernate or shutdown! so i want to remove it
I would re-install it, then use Revo uninstaller to uninstall it.
After the uninstall, Revo will clean the registry left overs, and any other leftovers as well.

As for the USB ports... IF they stop working, then go to the motherboard manufacturer's website and download the regular USB driver and install that.
IF we're talking about the ASUS STRIX Z390-F......
I don't see ANY USB drivers for any ASUS boards (Intel or AMD). So they're probably in the chipset driver.
So... just re-installing the chipset driver, should get your USB ports back.
You can install the latest chipset driver, right over top of the old one.

these values still exist after the uninstall? how could i remove them, the value on lowerfilters are AiCharger because USB ports not working
- - - Updated - - -
I deleted values in all lowerfilters containing AiCharger value , now i can disable AiCharger and no more malfunctioning USB problem after removing lowerfilter values.
Can confirm this works for leftover ones from changing motherboards. Other methods using uninstallation tools or disabling it directly will break without the tweaks.
