11 Best Open Source Software for Windows for Daily Use

For some people, software like Photoshop and Microsoft Office are also part of their daily basis and they can’t live without them.

The industry of software has transformed within the last years. Many software companies have changed their business model. Instead of one-time purchase, many software companies started applying subscription-based business model. As you know, Adobe is no longer sells its products — like Photoshop and Lightroom — in a one-time purchase method. You are required to pay monthly/yearly subscription fee. Later, Microsoft started following to adopt the same business model by releasing Office 365.

Actually, there are a bunch of open source software out there you can use to replace the proprietary software to lessen the dependence. Most open source software are released for free. You can use them legally without spending a dime, which is good for your balance sheet.
