I always believe in clean installing 8.1 over 8, but this is the way Microsoft recommends:
Get the free update
The Store is no longer open for Windows 8, so you'll need to download Windows 8.1 as a free update.
- Go to the Windows 8.1 download page and select your Windows edition.
- Select Confirm and follow the remaining prompts to begin the download.
- The update will download and install in the background while you use your PC to do other things. The installer will check to make sure you have enough disk space, that your apps and devices will work with Windows 8.1 or Windows RT 8.1, and that you have all the required updates.
In some cases, the installer might find something you need to take care of before you can continue installing the update. If so, you'll see a message telling you what you need to do.
Restart
After the update is downloaded and the first phase of the installation is complete (which could take between 15 minutes and a few hours, depending on your system and your connection speed), you'll see a message telling you that your PC needs to restart. It will give you 15 minutes to finish what you’re working on, save your work, and close your apps, and then it will restart your PC for you. Or you can restart it yourself.
Hello Bill,
Many thanks for your reply. However, the link you provided for Windows 8.1 is the one I used. After it downloaded there was no message about restarting. However, after it downloaded to my laptop under my own Downloads, the following is displayed: Win8.1-English-x64. I right clicked this expecting it to say run but it does not. I had to select an app to open and was offered Cyberlink to open. However, the options displayed again after were Open with ISO viewer; Mount as a virtual drive, View disc image. I don't see which option I need to pick to actually install it on to my laptop which is what I want to do as I'm not interested in saving it to a disc. When I selected Mount as virtual drive, it was saved to my CD Drive E. There is an option to select autorun or setup but I just get error messages. Because I currently have poor internet connection this took all day to download and now it appears it won't install. I don't know if there is any more advice you can give. Otherwise I shall see if there is any other website where I can download Windows 8.1 or I'll just wait for my updates offer me the chance to upgrade. Thank you.
