Windows 10 Will Be Free ** If your Upgrading from Windows 7 or 8 it will be free to upgrade for the first year.
But be aware good practice says new OS new install.
An upgrade will save you money but don't always assume it will be a smooth transition.
You may want to consider a factory reset before you upgrade to 10, to give your operating system the best chance.
O yeah you can have the free upgrade in the first year only.
Its not due for release until the summer.
