Sony just released the Xperia X driver for your windows PC, and it’s plenty helpful to have the correct driver installed whether you are looking at a simply job of file transfer from PC to device or vice versa, or looking to install a firmware or recovery or anything.
Without the correct drivers for your Xperia X, you cannot connect your device to PC, without which lot of fun could be missing.
The above are USB driver for your Xperia X, and should work fine on Xperia XA and Xperia X Performance too.
BTW, if you are looking to work on ADB, here are the ADB drivers for Xperia X.
