Update date time using batch file

For dual OS, sometimes windows show date incorrect. You need to go setting and force windows to synchronize its date time.
The easy way and fast is using batch files. Using text editor, create batch files for example datesync.bat in your desktop. Write or copy/paste this code:

Echo off
Echo Starting Windows Time Service
net start w32time

Echo Syncronizing Date Time
w32tm /resync
pause

Everytime your date show incorrect, run this script as administrator. It will start windows time service (should not be disable on services.msc) and syncronize date time from internet.
