try this: once you're in w10 desktop, try reboot it (not shutdown). once the screen goes blank/black, spam (press repeatedly) the particular key that gets you boot device menu/options. the settings of fastboot and secureboot must be disabled in bios.

it's funny that you cannot do this, because it's basically the common way to boot other bootable devices (dvd, usb stick). it's just that not all mobos/laptops use the same key for this purpose.

what computer are you using? (if it's a desktop computer tell me the mobo model; if it's a laptop tell me the brand and model)

the correct key to spawn for common asus laptops is esc key. firstly i think you need to set up your bios properly.

1. press and hold f2 key, power up your laptop. continue to press and hold the f2 key until bios screen is shown;
2. goto boot tab, enable launch csm; make sure fast boot is disabled;
3. goto security tab, make sure secureboot control is disabled; press f10 to save and exit bios; turn the computer off.

then,

1. plug in the usb stick;
2. press and hold esc key, then power your laptop. press and hold until you see boot menu list is shown;
3. select usb stick from the boot menu list.

if this cannot work, i don't know what will sorry.
I still can't boot to the bios screen. Can I use the setting>recovery> advanced startup to reach the bios screen???
edit: after tests are completed (when you decide to stop it), make sure check the first part to restore respective bios settings to the original ones, or your laptop will not boot normally.

yes you can.

you have a weird asus laptop. i just happened to have an asus laptop running w10 beside me. the first part was what i did to goto bios screen. the second part was how i choosed different usb devices to boot. tested and verified.

ok. built-in mem tests are short and simple. however it's not that thorough.

yeah i suspected that it's your igpu driver.

maybe a clean install will make it work. (since you were not able to goto bios or boot from other usb devices, i think you never did a clean install before)

Yes.

You mean the windows 10 update?

Hi , does anyone know what "svchost.exe (netsvcs)" service is for? it sucking my data. At first I tho it was updated , so I went to check and no , update was not running .

a better path is to upgrade, then clean up the disk and do a clean install. this will save you from all potential issues.

the upgrade is permanent if you don't revert to old os.
they should be the same. i use offline installer for cumulative update too (check stasio's link; 915MB for x64 os); didn't have issues previously.

know that it's normal that there will be delays for the os to process everything in background during shutdown, especially when fastboot is enabled (saving the os state to physical disk).

disabling fastboot means you sacrifice speedy boot time in order to have faster shutdown.
not sure what's happening sorry. just curious, how fast is your network bandwidth to the internet?

in terms of windows updates, i just turn off the option for windows updates delivery. besides that, i also turn off all apps that run in background. my network is almost always idle when i don't download stuff.

Ok well if it's a laptop, maybe you should find a hotspot (cafe or something) and do update. If it's a desktop, the better option is still offline installers. (Download it at locations with better bandwidth; it only takes few minutes to get the file downloaded, for instance, with 50Mbps connection)

go to Sudobrew they're 24/7 with good internet speed.. only problem is whether u can find a place to sit

Wouldn't recommend at all. Although they provide free WiFi service, it's quite bad - connectivity, stability, speed and security..
Unless you're only surfing net, casually checking emails, then I wouldn't suggest to go there.. My own 3G data is better than their WiFi

your main purpose is to get the offline installers. i think any cafe have internet connectivity that's way better than 384kbps.

no i think there are still many that are stuck too.

w10 anniversary update is coming upon or soon after expiry of free w10 upgrade offer. tbh build 14393 is solid so far. (didn't test edge's problems reported previously)
