Windows 8 won't start explorer on other accounts

Question

I'm using Windows 8 for a long time, but some days ago something weird happened. I'm able to log in and use computer like before, but other accounts cannot log in and it stops at the black screen.

I realized, that explorer.exe is not loaded in task manager. I tried to execute explorer.exe manually, but no help.

I was googling and found, that I could try sfc /scannow in cmd (ran as administrator) and this is from my CBS.log:

2015-09-19 17:02:02, Info                  CBS    Idle processing thread terminated normally

I selected that by the time (when that scans stops), there is more, older information, but flagged as CSI. I don't know if you need it, if yes, I will upload file somewhere.

Need to download NTP program (NTFS Permissions Tools from http://dbcstudio.net/software/npt/main.html) and then do these steps:

1. From "File -> Add folder" select any folder from "C:\Windows\", ie. "SysWOW64" (there are good permissions)
2. Now repeat last action, but select problem folder, for me it was "System32"
3. On folder "SysteWOW64" press right mouse click and select "Copy security settings", then press right mouse click on folder "System32" and select "Paste security settings"
4. That's all, now just restart computer
