If you use Windows and a version pre Windows 10 this may be for you. If not then why not just wander on by.
Windows 7 goes out of support in January 2020. Windows 10 was offered for free to upgrade for quite a while but was officially withdrawn many months ago. However ...
Upgrade to Windows 10 for freeI have recently upgraded an Acer laptop built in 2011. The hard disk had failed so I installed an SSD, added Windows 7 and the necessary device drivers, then upgraded to Windows 10 using the link above.
No issues after two weeks.
Windows 10 has become a lot more reliable in the past year though fanboys of alternative OS will of course have a contrary opinion on this. If you are a Windows user though it is now a reliable and stable platform. I have been using it on a new pc since last June and my much older laptop for a couple of weeks now.
I will be upgrading two more pc's in the coming days. My plan is to clean up each machine, clone the hard drive onto an SSD, swap the disks so that the new SSD is the system disk, then follow the upgrade path. If I encounter difficulties I should simply be able to revert to the original system disk.
Happy and free upgrading for those so inclined.
