So, you got a PC and someone decided to put a hacked version of Windows 7 on for you
or maybe you installed a DVD off the internet that has pre-cracked your software?

May be you just want to go legal BEFORE upgrading to Windows 10??

Whatever your reason, this is how you do it 🙂


Click on the Start Button and type: CMD (into the ‘Search programs and files’ field in the Start Menu)
The Start Menu will show ‘CMD.exe’,
Right-click the CMD.exe file and select Run As Administrator.

In the CMD window, type: slmgr.vbs -ipk <type your product key here>
To activate windows after changing the key, type: slmgr.vbs -ato

All Done 🙂

I started on computers back in the days of the Sinclair ZX81 and Spectrum, back when people were coming to terms with how great their new digital watch was. Even though I worked in DIY Shops, Fancy Goods, the building trade, DJ'ing etc, my main interest and passion was always in coding, graphics and games. I decided to take the plunge into computer shops in the mid 90's and in 2003 set up my own computer business. I have a simple work ethic which is I prefer to make a little money often, rather than charging a fortune and losing customers. This has proven to work for me and my customers. In all the years I have traded I have never advertised and yet each week, I get new customers through recommendations - there is no higher praise :)

What are your thoughts?
