Windows 10 changed date format on ExcelHaving recently installed Windows 10 on my main PC I hadn’t had many problems.  Until I went to use some previously created Microsoft EXCEL documents. It was then I noticed that Windows 10 had completely changed the date format on Excel from English UK to American US date format.

So instead of showing dd/mm/yyyy it shows the US version mm/dd/yyyy on all of my Excel Documents.

Thankfully there is an easy solution – which is to install the “English (United Kingdom)” language pack.

It sounds crazy that we have to do that – but it saves having to alter the cells on all of our documents and its quick and easy to do.
