It still seems that WMIC is the quickest way to get CPU information on the console:
T510-PSO C:\bin\rdp> wmic cpu get name,CurrentClockSpeed,MaxClockSpeed
CurrentClockSpeed MaxClockSpeed Name
2667 2667 Intel(R) Core(TM) i5 CPU M 560 @ 2.67GHz
T510-PSO C:\bin\rdp> wmic path win32_Processor get Name,NumberOfCores,NumberOfLogicalProcessors
Name NumberOfCores NumberOfLogicalProcessors
Intel(R) Core(TM) i5 CPU M 560 @ 2.67GHz 2 4
Actually, wmic cpu is shorthand for wmic path win32_Processor, so this works fine:
T510-PSO C:\bin\rdp> wmic cpu get name,CurrentClockSpeed,MaxClockSpeed,NumberOfCores,NumberOfLogicalProcessors
CurrentClockSpeed MaxClockSpeed Name NumberOfCores NumberOfLogicalProcessors
2667 2667 Intel(R) Core(TM) i5 CPU M 560 @ 2.67GHz 2 4
The reason is that cpu is an alias:
T510-PSO C:\bin\rdp> wmic alias cpu list brief
FriendlyName PWhere Target
CPU Where DeviceID='#' Select * from WIN32_PROCESSOR

After watching an autologon system not logging on automatically over the past years, the pattern seems to be that at least major, and some less minor Windows updates remove autlogon parts of the registry.
I’m not sure where the boundary between “major” and “less minor” lies (though I suspect “cumulative updates” and larger), nor if more than these values are affected:
- key
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon"
- value name
AutoAdminLogon gets removed or becomes value 0
- value
DefaultUserName gets removed
- value
DefaultPassword gets removed
This means that now after each startup, I need to schedule a task that runs a script setting the values I need depending if a password is needed or not.
The script also needs credentials, so I need to figure out how to properly do that.
I still need to decide between PowerShell or batch file script, as I already have the batch file from How to turn on automatic logon in Windows and automatic logon in Windows 2003.
For my future reference, some more links on things that can get deleted:
Hopefully these links will help me writing the scripts:

Since Chrome changes over time, the batch file below from [WayBack] Run chrome in fullscreen mode on Windows – Stack Overflow also changes:
@echo off
echo Countdown to application launch...
timeout /t 10
"C:\Program Files (x86)\chrome-win32\chrome.exe" --chrome --kiosk http://localhost/xxxx --incognito --disable-pinch --no-user-gesture-required --overscroll-history-navigation=0
exit
On most of my systems. Chrome is at C:\Program Files (x86)\Google\Chrome\Application\chrome.exe, so I need to change the path anyway.

I knew I could run shell:startup and similar shortcuts from the Explorer address bar or the Windows-R “run” prompt.
First I learned that via [WayBack] tablet – How to set Google Chrome to automatically open up and in full screen – Super User.
Then via [WayBack] “shell:startup” – Google Search, I found [WayBack] Location of the Startup folder in Windows 10.
It took a while before I realised you can also run them from the command-prompt, batch-files or PowerShell scripts prepending them with start:
start shell:startup
That one will open a new explorer window in the user startup folder from either the command-prompt, a batch file or PowerShell script..
The shell: shortcuts can contain spaces. So for instance there is shell:common startup that opens the common startup folder.
Starting it from the command prompt, batch file or PowerShell script is different: because of the spaces you will get the error on the right unless you add double quotes:
start "shell:common statartup"
All shell: commands that you can run in the same way: double quotes work for both the ones requiring spaces and the simple ones nor requiring spaces.
Virtually each new Windows version (even most Windows 10 major builds) gets new shell: commands.
A good source with an up-to-date and historically accurate of shell: commands list is at [WayBack] Shell Commands to Access the Special Folders in Windows 10/8/7/Vista/XP » Winhelponline,
You can get the current list by recursively enumerating the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions registry key, which consists of a list of Explorer folder GUIDs having Name, ParentFolder and RelativePath value names.

[WayBack] How to turn on automatic logon in Windows
Describes how to turn on the automatic logon feature in Windows by editing the registry.
Most archivals of the above post fail with a 404-error after briefly flashing the content, but this particular one usually succeeds displaying.
It is slightly different from the one referenced in my blog post automatic logon in Windows 2003, and because of the archival issues, I have quoted most of it below.
A few observations, at least in Windows 10 and 8.1:
- Major Windows 10 upgrades will disable the autologon: after each major upgrade, you have to re-apply the registry patches.
- If the user has a blank password, you can remove the DefaultPassword value.
- Empty passwords allow local logon (no network logon or remote desktop logon), no network access and no RunAs, which can actually help improve security. More on that in a later blog post
- For a local machine logon, you do not need the DefaultDomainName value either (despite many posts insisting you need them), but you can technically set it to the computer name using
reg add "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefaultDomainName /t REG_SZ /d %ComputerName% /f
- If another user logs on and off, the values keep preserved, so after a reboot, the correct user automatically logs on
- you need a full reboot cycle for this to take effect
- The AutoLogon tool does not allow blank passwords
I wrote a batch file enable-autologon-for-user-parameter.bat that makes it easier:
if [%1] == [] goto :help
:enable
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v AutoAdminLogon /t REG_SZ /d 1 /f
:setUserName
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefaultUserName /t REG_SZ /d %1 /f
:removePasswordIfItExists
reg delete "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefaultPassword /f
if [%2] == [] goto :eof
:setPassword
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefaultPassword /t REG_SZ /d %2 /f
goto :eof
:help
echo Syntax:
echo %0 username password

When configuring a web-based kiosk for someone with Alzheimer’s disease, I wanted to start Chrome in full-screen kiosk mode.
Chrome full-screen kiosk mode
The secret for full-screen kiosk mode is to pass the -start-fullscreen command-line option. Thanks [WayBack] User ginomay89 – Super User for answering that in [WayBack] tablet – How to set Google Chrome to automatically open up and in full screen – Super User.
Finding chrome
At first I thought about differentiating on the chrome.exe location that you can find in the registry. This turned out to be depending on how you install Chrome:
- locally for the current user by a non-local-administrator user (by default the location is under
%LocalAppData%)
- globally for all users by a local-administratator user (by default is under
%ProgramFiles(x86)%)
Oddly, there is no way (not even by denying UAC elevation!) for a local administrator to install Chrome for only the current user.
This is odd, as when non-local-administrator denies UAC, the installation is locally to the user.
Then I remembered there are two ways for Windows to find an application
- On the
PATH
- Via the start menu (which includes anything on the
PATH)
The cool thing is that the start command does the latter, so I came up with this batch file that starts chrome with the -start-fullscreen parameter that will initiate kiosk mode with the default chrome settings:
start "Chrome Kiosk Mode" chrome --start-fullscreen
In case I want to compare the registry settings
Basically sorting out the registry settings would mean parsing the references to chrome.exe (often with extra parameters) in the below registry key/value-name pairs.
One day I might need to do this for different reasons, but currently the start trick suffices.

Based on zzz but filters current user, and listener session.
:: https://stackoverflow.com/questions/36715033/how-to-logoff-all-users-on-windows-from-command-line-as-a-domain-administrator
:: The findstr bit filters out the current session (starts with ">") and session 65536 (which is the listener)
for /f "skip=2 tokens=2,3 delims= " %%a in ('query session ^| findstr /v /b ">" ^| findstr /v "65536 Listen"') DO (
echo %%a|findstr /xr "[1-9][0-9]* 0" >nul && (
logoff %%a
)
echo %%b|findstr /xr "[1-9][0-9]* 0" >nul && (
logoff %%b
)
)

[WayBack] How do I get the application exit code from a Windows command line? – Stack Overflow solutions below.
Note they ONLY work when nobody sets the ERRORLEVEL environment variable.
- – [WayBack]
-
something.exe
echo Exit Code is %errorlevel%
– [WayBack] Samuel Renkert
-
start /wait something.exe
echo %errorlevel%
– [WayBack] Gary
-
@echo off
my_nify_exe.exe
if %ERRORLEVEL% EQU 0 (
echo Success
) else (
echo Failure Reason Given is %errorlevel%
exit /b %errorlevel%
)
– [WayBack] Curtis Yallop
- It’s worth noting that .BAT and .CMD files operate differently.Reading https://ss64.com/nt/errorlevel.html it notes the following:
There is a key difference between the way .CMD and .BAT batch files set errorlevels:
An old .BAT batch script running the ‘new’ internal commands: APPEND, ASSOC, PATH, PROMPT, FTYPE and SET will only set ERRORLEVEL if an error occurs. So if you have two commands in the batch script and the first fails, the ERRORLEVEL will remain set even after the second command succeeds.
This can make debugging a problem BAT script more difficult, a CMD batch script is more consistent and will set ERRORLEVEL after every command that you run .
This was causing me no end of grief as I was executing successive commands, but the ERRORLEVEL would remain unchanged even in the event of a failure. – [WayBack] RockDoctor

You can use:
IF "%~1" == "" GOTO MyLabel
to strip the outer set of quotes. In general, this is a more reliable method than using square brackets because it will work even if the variable has spaces in it.
Source: [WayBack] jamesdlin answering on [WayBack] windows – What is the proper way to test if a parameter is empty in a batch file? – Stack Overflow
The tilde (~) strips out double quotes from the command as per
C:\>help for | findstr "~"
%~I - expands %I removing any surrounding quotes (")
%~fI - expands %I to a fully qualified path name
%~dI - expands %I to a drive letter only
%~pI - expands %I to a path only
%~nI - expands %I to a file name only
%~xI - expands %I to a file extension only
%~sI - expanded path contains short names only
%~aI - expands %I to file attributes of file
%~tI - expands %I to date/time of file
%~zI - expands %I to size of file
%~$PATH:I - searches the directories listed in the PATH
%~dpI - expands %I to a drive letter and path only
%~nxI - expands %I to a file name and extension only
%~fsI - expands %I to a full path name with short names only
%~dp$PATH:I - searches the directories listed in the PATH
%~ftzaI - expands %I to a DIR like output line
values. The %~ syntax is terminated by a valid FOR variable name.

Windows if full of undocumented gizmo’s, like find alternative for wc -l counting all lines in a file: [WayBack] File Line Count
Use FIND command to count file lines, store line count into a variable.
| Description: |
Running the FIND command with option /v and empty search string will find all lines
Running the FIND command with option /c will output the line count only.
The FOR command with option /f will parse the output, the line count in this case, and the set command put the line number into the cnt variable. |
| Script: |
1.
2.
3.
4.
|
set file=textfile.txt
set /a cnt=0
for /f %%a in ('type "%file%"^|find "" /v /c') do set /a cnt=%%a
echo %file% has %cnt% lines
|
|
| Script Output: |
 Script Output |
textfile.txt has 50 lines

[WayBack] Stupid command-line trick: Counting the number of lines in stdin | The Old New Thing
Windows doesn’t come with wc,
but there’s a sneaky way to count the number of lines anyway:
some-command-that-generates-output | find /c /v ""
It is a special quirk of the find command
that the null string is treated as never matching.
The /v flag reverses the sense of the test,
so now it matches everything.
And the /c flag returns the count.
…
The reason dates back to the original MS-DOS
version of find.exe,
which according to the comments appears to have been written
in 1982.
And back then, pretty much all of MS-DOS was written in assembly
language.
