Got a new machine with win 10 on that they set up in the shop. It's all in English, apart from the days of the week and the year which are Thai, year being 2562. There must be a simple way of changing it but cannot see it.

Windows side menu, Settings (2nd one up, the cog)
Time & Language

If you can't find it that way, right click on the time in the bottom right of the taskbar and click on Adjust date/time.

 

Right hand of opened window click on Additional date, time & regional settings

 

Under Region, click on Change date, time or number formats

 

You can also get here directly through the (old) control panel. If the View by: is set to Category, click on Clock and region. If the View by is set to large or small icons, click on Region.
