Putty connection to AWS Linux instance

I have registered my personal AWS account today (FINALLY). The entire process was easy for me, however, I encountered an issue when I try to connect to AWS Linux instance from ssh within Windows.

I am always using Putty for connection to my Cloud servers. Thus I firstly tried Putty in same way I used to connect to AliCloud. Unfortunately I encountered the following error message.

Then I tried to use ssh -i xxx.pem ... command in CMD console. However, AWS sent back the following complaints:

It seems a permission issue which can easily been solved using chmod in Linux. However, I am using Windows and I'm really not familiar with the complicated "permission" rules in Windows. Some online articles presents solution of this issue using icacls. However, it did not work in my case.

Official doc of AWS has presented a really useful solution. It's quite simple and efficient. Following this tutorial, I executed Putty Key Generator, load my "xxx.pem" file and export an .ppk key file.

Then in Putty interface, I load my .ppk key file (as shown below) and try the ssh connection as usual. And it works.
