Windows 10

I wonder if it makes a difference what you have upgraded from and which computer.  Apart from the most recent problem with the upgrade its been trouble free on my Acer laptop which wasn't more than a few months old when I went from 8.1 to 10. However I remember XP Pro with great fondness! 

I've had similar problems to ivor.  Six months ago, I spent a small fortune on a high end HP computer with an i7 processor and 16 Gb of Ram.  Everything was fine until August 27 when there was a major upgrade of Windows 10. From that day onwards, it would load ony a few web pages but not the majority and there were loads of other niggles that weren't there before the upgrade.  A system restore back to before the upgrade seemed to solve the problems for a short while - until the upgrade loaded again.  Having eliminated all possible causes - internet connection, conflict with AV software, firewall settings etc, I eventually took it back to Currys from where it originated. After 3 trips backwards and forwards to the store (and a total mileage of over 120 miles!), two of their techies were still baffled as to the cause - other than the update.  (MS telephone support appears to have been withdrawn after 29 July when the free W10 upgrade finished). When they started talking about trying a new hard drive / network card / etc etc etc, I told them I had had enough and fortunately both they and the store manager were sympathetic.  I was given a full refund and put it towards a Mac - which is something I have been considering buying for years.  Although it has, so far, been a steep learning curve - and I miss some of the familiar Windows features, I am now experiencing trouble-free computing and have my fingers crossed that I have made the right decision!

Beginning to wish that I had stayed with "7"

Updates take a age on ten, even overnight. On start up again I'm told that a restart is scheduled for a certain time usually in the next ten minutes......So much for me thinking all the restarts had been done overnight......
