Windows 10 (the newest version of the Windows system) has proved to be a problem for some people who try to install it on older computers. In some cases, upgrading to Windows 10 can cause software (programs that you have installed) to stop working and also hardware (such as printers and scanners). On a number of older, upgraded computers, Windows 10 stops working properly itself, making the computer almost unusable.
Microsoft was causing windows to pop up on your computer, telling you that you should upgrade to Windows 10. This should not be happening any longer. If you are are still quite happy with Windows 7 and Windows 8, you should be able to continue using it. Microsoft is committed to support these older versions of Windows until 2020 at the earliest.
Windows computers are the least secure and most vulnerable to malware and viruses. That is why computers running other systems (such as those that I have described below) don't need anti-virus software installed. So, you may want to consider:
1) Purchasing A New Apple Mac PC
Apple Mac computers are well designed, well built computers. They are also quite easy to learn to use. The downside is the price - they are expensive.
2) Purchasing A Chromebook
If you don't really need to do much more than email and a little web browsing, a Chromebook might be great idea for you. If you already use Google Chrome as your web browser, you should have no difficulty using one, For between £200 to £250, you can buy a brand new laptop that is light to carry and has a very long battery life.
3) Upgrading Your Existing Computer To Linux
If your existing computer is in a good condition and your believe it has a few years of life left in it, then I could re-install it with Linux. Unlike Windows, Linux and all the software that you need to use on it, is free. I charge approximately £40.00 to upgrade computers to Linux for my customers and give them a quick training session in how to use it. I have upgraded about 15 people so far. No one has needed any additional training and no one has wanted to go back to using Windows again.
