This post will let you know how to install Tamil or any other regional language that you use in your Windows 10 machine. In Windows 7, I was able to view Tamil fonts in Chrome, IE and in other in-built apps. But after upgrading to Windows 10, I could not view these Tamil fonts in any of my apps. I did a little search, found a fix and I am going to share it to my fellow Tamil folks!
Before I start, Let me tell you why it's not working in Windows 10. Windows 7 had some pre-installed Tamil fonts like Latha and Vijaya by default. But in Windows 10, these fonts had been moved to a pack called "Supplemental Tamil Fonts" which is marked as a Optional feature. So enabling this optional feature, will help us to get our language back.
Follow the below instructions to enable Tamil letters on Windows 10,
Click the Start button.
In Settings, click Time & language.
Click Region & language.
All regional fonts to your country will be listed, If Tamil is not included in your languages, click the "+" icon next to Add a language.
Scroll to find Tamil, then click on it to add it to your language list.
That's it! You should be able to read your Tamil articles. :)
