After running this test I tried sfc and it ran this time; it said there were no problems. Also tried to clear log files the cmd ran and event viewer said only 9 error events but when I opened the admin events log it showed 138 of them.

Which test? PATH, Safe Mode, or New account?

I'm going to suggest the PowerShell version again - it's much more simple. Basically the same function, but without all the cmds that might obscure the cause
See: Event Viewer: Clear All Events

Foreach-Object not reconized as internal or external commands, etc

After running the script, a few entries are added into the system event log that certain logs were cleared. This is due to the script clearing them alphabetically and several are cleared after the system event log. I wanted it to be super tidy so I added another line to clear the system event log one more time after everything else was cleared. Not sure if this is the best way to do it but thought I'd share my modification.

I have also confirmed that this script works great on Windows 8.1 and Windows 2012 R2.

Code:

@echo off
FOR /F "tokens=1,2*" %%V IN ('bcdedit') DO SET adminTest=%%V
IF (%adminTest%)==(Access) goto noAdmin
for /F "tokens=*" %%G in ('wevtutil.exe el') DO (call :do_clear "%%G")
wevtutil.exe cl System
echo.
echo Event Logs have been cleared! ^<press any key^>
goto theEnd
:do_clear
echo clearing %1
wevtutil.exe cl %1
goto :eof
:noAdmin
echo You must run this script as an Administrator!
echo ^<press any key^>
:theEnd
pause>NUL

Hi Zardoc,

Thanks for your sharing, but I have a question that how to clear the Windows log just the part of system, it's only need to clear the system log under Window logs. Thanks in advance!

Hi Brink,

Thanks for your reply, if I'd like to clear the system log with one click completed, so how to do work using the bat command?

Here is my code for those wanting an even smaller batch file and quicker clean:

Step 1: Copy/Paste the code into Notepad.

Code:

@echo off
for /F "tokens=*" %%G in ('wevtutil.exe el') DO (call :clear "%%G")
:clear
echo clearing %1
wevtutil.exe cl %1
goto :eof
exit

Step 2: Save as "All Files" and make sure you have ".bat" at the end of the name.
Step 3: Right click on the newly saved bat file, and click "Send to.. Desktop"
Step 4: Right click on the newly made shortcut on the Desktop and click "Properties" then click "Advanced" then check the box "Run as Administrator" and hit "OK"

Now you can simply double click the shortcut at your leisure and quickly clear event logs. No annoying Yes|No prompts to clear logs and no "click to exit prompt" pauses after clearing and all done with 141 bytes of code.

Thanks, works great win 7Pro, 64bit
