I use a Lenovo tablet with Win 10 for presentations at weekend & evening meetings but I am having intolerable problems with Windows 10. The tablet is loaded with MS Office& 2 or 3 apps plus Trend Maximum Security.
Unfortunately Windows 10 does not allow me to choose when to install updates. To compensate I now turn the tablet on the morning of any meeting to make sure overnight updates are processed, then I put it to Sleep to avoid rebooting and risking another update.
However that strategy failed about a week ago. After waking it from Sleep it was flaky so I had to reboot and sure enough another update. It finally finished that update 3 minutes before I took to the stage - phew!!!!.
A few days ago it upgraded again but now Cortana, Play Store and some of my 3 apps won't display properly. This morning I turned it on again and another update started but that failed so it looks like it's gone back to a previous version again. Now I don't know if I can risk putting it to sleep while I travel to a meeting in case it decides to try a lengthy update again.
Windows 10 on my desktop that is left running 24/7 seems fine as updates happen overnight, but it's just not workable on a tablet that I am so dependent on. I know Windows 8.1 has many faults but from what I recall it let me choose when to update.
I am after suggestions. Do I revert to Windows 8.1, and if so how, or do I buy a new Android or iPad tablet that I can rely on to be there at my service, not the other way around?
