I have a fresh Windows 10 install (not an upgrade) on my Lenovo L540. It is perfectly running until I connect to internet. Once I do that, after I restart the computer (the restart it taking several long minutes), it never boots up again.
I can just see a Windows logo and loading circle for ever. I tried to disable automatic updates, also upgraded graphic drivers...
No success. Is there some log I can watch?


edit: HyperV is disabled.

  • I don't think that connecting to the Internet caused the issue. It sounds more like a corrupt install of Windows. I would try a clean install of Windows. – Tim G. Jul 30 '16 at 19:34
  • I did a clean install of Windows 8x times today! I'm writing it is the clean install.. – o..o Jul 30 '16 at 19:36
  • The initial updates for Windows 10 (from your 'fresh' install to the 'current' version) are potentially large, and depending on the hardware, it could run hours. I would give it a night and see if that helps. – Aganju Jul 30 '16 at 19:50
  • Didn't help during the whole night. Seems to be a problem with cumulative update KB3140743, but I don't know how to uninstall that, because I'm not able to boot it even into safe mode.. – o..o Jul 31 '16 at 5:03

So was a graphic card driver. So I made a fresh install, blocked all Windows updates by setting them to notify restart and deffer the upgrades, whant I used wushow.diagcab to block the wrong one.
