I was very exited about Windows 10 when first I heard release of this.I wanted to get it as soon it releases .But After using for one day I come to know that this is not good as Windows 7.The main advantage of this OS is security and regular update and disadvantage is background internet access by Windows 10.This OS is not faster than its previous version.
Like: I like design and graphics, The regular updates reduces security risks.Free upgrades for Win 7 and Win 8 users.
Dislike: User Interface is not user friendly, No option to disable updates in case you have limited data available, Very heavy use of hardware, background internet access.You may face drivers problem as old drivers may not be compatible with Windows 10.
Who Should use: Anyone can use who loves graphics, latest OS, unlimited Internet access and specially who do work related to Online banking.
Who Shouldn’t use: Anyone who don’t have unlimited internet plan work for development purpose.
