Windows 8

If you have windows 8 and get the pop-up across your screen to update to 8.1 free. The pop-up actually comes from Microsoft, but I suggest you do not do it!! Firstly, you will need to create a Microsoft account. DO NOT FORGET THE PASSWORD YOU USE! Secondly, the update process is quite lengthy. Thirdly, all non Microsoft programs, like your anti-virus disappear. Your data remains but you have to reload the programs . It's like doing a "refresh"
Fourthly, most of you will end up with an online account and you will have to sign in with the password each time you boot up, this can also be fixed by changing the account to a "local account". We have seen it that the computer becomes unusable without an internet connection! So, if you boot up and try to sign in , you can't get into your account. It reminds me of Hotmail, when it decides it no longer likes your password. Good luck getting back in!
