When it comes to the automatic updates I just let it get on with it,any technical type stuff that needs doing with the computer and I take it to my granddaughter to sort for me[I've just had to ask her by text message what the heck a dongle is!!]I was just curious as to why it would automatically turn off on reaching 30% and then wait until the next time I turned it on to complete the run up to 100% instead of doing it all in the one go.
Very "broad brush" outline of what occurs... not actually 100% accurate but gives the main idea ....
Whilst the system is running there are a whole load of "active programs" al doing their thing, far more than you realise. "Active" programs cannot be modified whilst working (a bit like trying to change a tyre whilst doing 30mph), so the system "prepares" new files with the updated data embedded within and stores them on the hard drive, along with a load of special instructions for the machine to do next startup ... thats the "30%" activity.
When you do the restart the special instructions file loads first and runs ... windows does not actually start .... and all the windows files that need updating are replaced with those prepared earlier, this taks a little while as here are a lot of them usually ... once all the files have been replaced it is possible for windows to actually start and run ... and the update is deemed complete.... thats the "70%" part ....
Throughout this process if you watch the hard drive activity light, the hard drive is working VERY hard as many files are rewritten/renamed/replaced ... that is why the system tells you not to switch it off .. if you do you will most certainly have corrupted files as so many are in the middle of being changed and you have just stopped them dead.... !!
Hope that helps a tad ..
