There are plenty of 3rd party softwares out which will not only help in capturing screen-shot but also let your edit images just after capturing them. There are hundreds of them, but I prefer two of them listed below.
This is the most downloaded and recommended by people all over the globe. Bandicam lets you capture screenshots and records your screen as well. You can download Bandicam from there official website but it will be a free verion which comes with certain size limitation and Bandicam watermark at the bottom of the video (not image).
You can remove these limitation by buying Bandicam. It is just going to cost you few bucks.
Apart from Bandicam, I would prefer you to go for Lightshot because it is one and only capturing tool which is pre-synced. Every time you snap any image you will get a link to it which is accessible all over the internet. You can directly add link to your blog post or any where else which removes all the hassles of uploading images.
If you don't prefer to go for 3rd Party Software then you get an inbuilt feature apart from 'PrintScrn' button and that is Snipping Tool. You can follow steps below to use Snipping Tool.
1. Click on Start Menu
2. Navigate to Accessories and look for Snipping Tool there
3. Just after clicking on it, you will see a popup on the screen which few options
4. Click on New and it will let your select any portion of your screen which you want to capture.
Just after capturing your image will open with Paint which will also let you edit your image. After everything is done you can save your image by clicking Ctrl (Control Key) + S.
