The offer to upgrade to Windows 10 ends on July 29th and after July 29th if you want to upgrade your Windows 7 or Windows 8 / 8.1 it will cost roughly $179 ( depends where you buy it from ).
If you are running Windows 8 / 8.1 , I think it is a no brainer to go to Windows 10 ,which is a much improved experience on Window 8 / 8.1.
If you are running Windows 7 it really depends if you are happy where you are as it will be supported till Jan 2020 so by that time you will probably have changed your computer.
The nag to make the move to Windows 10 should end after July 29th and will probably be removed via an update.
What To Do If You Are Going To Upgrade ?
- Uninstall your antivirus if it is anything other than the one supplied by Microsoft via the uninstall tool supplied by the maker of the antivirus
- Do a backup
- Remove any bogus programs such as – registry cleaners , “speed up my pc” programs
What Do I Think Of Windows 10 ?
I like it now that all the issues have been worked out.
