Windows Operating Systems life cycle

At regular interval, Microsoft stops providing support to their previous Operating System. I am wondering how many people know about it and do they really understand the effect of this on their PCs. Hence, I thought about writing this article.

Every Microsoft product has its lifecycle. It starts when it was launched and ends when it is no longer been supported. It is useful to know when your OS is no longer being supported so that you can take decision about upgrading OS and make necessary changes to your applications.

Microsoft announces End of Support date for their products that means from that particular date, Microsoft will no longer offer any fixes, updates or technical assistance of that product. As a user, you will have to make sure that you’ve installed latest update or service pack available for that program.

Here are some key dates from Microsoft:

Operating System

End of extended support
Windows XP
Service Pack 3
14/04/2009
08/04/2014

09/01/2018

Windows 10
N/A
13/10/2020

Note: To continue receiving support for Windows 7, please make sure that you’ve installed Service Pack 1.

A message box appeared stating that it could not detect the USB device. I never had any problem when I was using Windows 7. I used to plug my phone to PC using USB cable and access phone storage as USB drive. I typed my query in google and most of the articles suggested that I should installed HTC Sync Manager and then connect my phone.
