Notebook doesn't boot, error: autochk not existing, skipping AUTOCHECK

You can try to run this in CMD as admin. Those startup keys are required by Windows.

Code:

reg add "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon" /v "Shell" /t REG_SZ /d "explorer.exe" /f
reg add "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon" /v "Userinit" /t REG_SZ /d "C:\Windows\System32\userinit.exe," /f
reg add "HKLM\Software\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Winlogon" /v "Shell" /t REG_SZ /d "explorer.exe" /f
reg add "HKLM\System\CurrentControlSet\Control\Session Manager" /v "BootExecute" /t REG_MULTI_SZ /d "autocheck autochk *" /f
reg add "HKLM\System\CurrentControlSet\Control\Session Manager" /v "SETUPEXECUTE" /t REG_MULTI_SZ /d "" /f

rue but just give them the all the numbers you have they relate to model and ask them what series that relates to on website. Agree, don't let them on device.

Well....I mean...well...I will...consider it. Thank you.

Yes, OK, thank you, sorry, what does that mean, what for, what does it do? Those keys are not available on Win at the moment?

You should also remove Windows.old, since it might causing problems.

OK, I will do it, What problems? Why? I tried to remove Windows.old, but there are files / folders which I cannot delete or copy at the moment. "No access, cannot be deleted
Is this malware? And where does it come from?
C:\Windows.old\WINDOWS\syswow64\autochk.exe
C:\Windows.old\WINDOWS\System32\autochk.exe

Thank you for the link.

Enter said:

C:\Windows.old\WINDOWS\syswow64\autochk.exe
C:\Windows.old\WINDOWS\System32\autochk.exe
