After a number of failed attempts to upgrade to Windows 8.1 as requested, on a 2013 Compaq CQ2000PC, where it went off for 20-30 minutes then said it had to reset to 8, I finally got a message from HP directly saying:
"
HP has not tested this PC with Windows 8.1
For this reason, HP is unable to provide update instructions or Windows 8.1 drivers. You may lose basic functionality and stability if you try to update your system. "
Had I been on an old machine running Vista or the like, maybe this would make sense, but when the store kept asking me to upgrade and the PC was only a year old I don't think the service is quite up to what we'd expect.
Anyone else suffered from this issue and is it terminal? Now I've replaced the old desktop format I'm perfectly happy with 8 as it is, but if there's more it would be nice at least to have the option.
