Slow logon to Windows 8


My windwos 8 system took more then 120 seconds to login.

This message was shown in the eventviewer,
Sourcee:Winlogon, Eventid: 6006 :  “The winlogon notification subscriber <GPClient> took 124 second(s) to handle the notification event (Logon).

After a bit of research I found out that disabling the autotuninglevel was the solution.
(was also a solution in windows vista and windows 7)

  1. Start an elevated command prompt
  2. type “netsh” followed by enter
  3. type “interface tcp set global autotuninglevel=disabled” followed by enter
  4. Reboot the system


Remote Logins Are Currently Disabled


You receive this message when trying to login to the server “Remote logins are currently disabled.”

In order to enable logon again  the “CHANGE LOGON /ENABLE” command must be issued.

To do this remotely we need the psexec.exe utility, this can be downloaded from

Start a command prompt :

Use this syntax
psexec.exe “\\SERVERNAME\ change logon /enable”



change logon command syntax:

change logon /enable | /disable | /query

The parameters that are used by the change logon command are:

/enable: Use this parameter to turn on logons from client sessions.
/disable: Use this parameter to turn off any further logons from client sessions. Currently- logged-on users are not affected.
/query: Use this parameter to display the current logon status.

Windows 8 awakes spontaneously from sleep


In an elevated command prompt you can check with this command which device caused the last awake of the system.

powercfg -lastwake


to find hardware devices that can wake your computer, run the following command:

powercfg -devicequery wake_armed


You can change this settings via device manager,
Properties of the device.Choose the powermanagement tab and uncheck

Allow this device to wake the computer check box and click OK


Also check the scheduled tasks that are allowed to wake you computer

powercfg -waketimers

You can edit this scheduled task in the Windows task scheduler.


Create A Custom Shutdown or Restart Button


Right click on  the desktop

choose “New>Shortcut” and enter


for Shutdown use  C:\windows\system32\shutdown /s /t 0
for Restart use C:\windows\system32\shutdown /r /t 0

This will create a  shutdown shortcut on your desktop

associate a shutdown image to the icon.
right click the icon, choose properties,
“shortcut” tab -> “change icon” button.

choose the red “Turn Off computer” icon  and click “OK”

For windows 7 or 8
Move this shortcut to : C:\ProgramData\Microsoft\Windows\Start Menu\Programs

now  the icon of shutdown is shown as tile in the Windows 8 Metro interface.



To show a comment for 5 seconds while shutting down or restarting, add the  “-c” switch :
%windir%\system32\shutdown.exe -s -c “going to shut….” -t 5

To put the system into standby you need the rundll32.exe command
C:\WINDOWS\System32\rundll32.exe powrprof.dll,SetSuspendState Standby

C:\WINDOWS\System32\shutdown.exe -l

C:\WINDOWS\System32\rundll32.exe powrprof.dll,SetSuspendState Hibernate


there is another and easier way Download this vbs script from Digital Inspiration,
save the file and double click it to create the buttons on your Windows 8 start screen.

Windows 8 random freezing issue


Problem : the system may randomly stop or freeze

Solution : Run this command in an elevated command prompt :

bcdedit /set disabledynamictick yes


–> What it will do is stop Windows from coalescing CPU clock ticks when idle, a feature added in Windows 8 for power savings.
