Windows 10: Acer ES1 boot times far slower than 8.1, and erratic

Acer ES1-111m-P2YU with 4GB RAM, conventional SATA 5400rpm drive, windows 8.1 upgraded to Windows 10, x64 [both].
Windows 8.1 would boot in ~20 seconds. Windows 10 boots up in not less than 60 seconds, and as long as 122 seconds [in the log so far]. I have set advanced Properties settings to favor Performance over everything, for system and for programs [though I'm not at the point of running many programs yet]. Power plan settings don't seem to make a diff. High Performance plan takes just as long as Balanced

Every unnecessary service is disabled, and Startup items: only one I left 'enabled' is the Intel DPTF
I note that Acer also has its own Energy saving service "epower" which kicks off a few processes.

in the Events log, under Applications & Services, Microsoft, Windows, Diagnostics - Performance - full of warnings and criticals and Errors - most of which are merely reporting out-of-bounds Boot Performance and Shutdown Performance. Along with these are a few errors re: Services that take too long, decaying boot up. these seem to change with every boot - so there is no pattern. though some are repeat offenders, they are not repeat offenders on successive boots : one here, one there.

i've tried some of the standard "fixes" like disabling fast boot and enabling fast boot - no diff.

how to debug?

also, in the system event logs there are no significant errors, and no device errors.

10 slower to boot than 8.1

A bit later than the other replies in this string and it seems Microsoft have not resolved the boot-time matter over the almost 1 year this string has been running...

I updated my Dell Optiplex7020 (i7) in June 2016 (Windows 10-Pro 64bit) - The first thing I noticed was the very much longer boot-time; Windows8.1 was up and running within the blink of an eye after keying in the log-on password; much quicker than Windows7
on a similar machine and a lifetime quicker than XP-Pro (I was so impressed with 8.1).

Also, everything worked just fine with Windows8.1; now I have Windows10 I seem to be spending a lot of time reading web-pages to find fixes for the many problems Windows10 has brought to me.

At least the tools I need to earn my salary work...

 

How to speed up Boot time WIndows 10

I am having slow speed Booting .. its like 20 seconds slower than Windows 8.1 . That is worse *sigh* Any tips please?

I have a SSD that is only 18 GB, is it possible that I can use it for cache? and faster boot? I don't have drivers from Acer. I can't even install Intel Rapid Start
