Check the state of the OS and proceed accordingly.

@Matthew Wai, does your code do exactly the same as @Kyhi's code?

I just found a subtle difference. See the test results below:

Kyhi said:

Code:

set "params=%*"
setlocal EnableDelayedExpansion
cd /d "%~dp0" && ( if exist "%temp%\getadmin.vbs" del "%temp%\getadmin.vbs" ) && fsutil dirty query %systemdrive% 1>nul 2>nul || (  echo Set UAC = CreateObject^("Shell.Application"^) : UAC.ShellExecute "cmd.exe", "/k cd ""%~sdp0"" && %~s0 %params%", "", "runas", 1 >> "%temp%\getadmin.vbs" && "%temp%\getadmin.vbs" && exit /B )
%windir%\system32\reg.exe query "HKU\S-1-5-19" 1>nul 2>nul || (
echo.
echo ============================================================
echo ERROR: Run the script as administrator.
echo ============================================================
echo.
echo Press any key to exit...
pause >nul
goto :eof
)

I put it in a .bat file "E:\$ Testing\Kyhi.bat" and ran it. The output was:

Code:

'E:\$' is not recognized as an internal or external command,
operable program or batch file.

C:\Windows\system32>

The code does not work because the file path contains a space.

Code:

@echo off
(Net session >nul 2>&1)||(PowerShell start """%~0""" -verb RunAs & Exit /B)
Echo Hello & pause

I put it in a .bat file "E:\$ Testing\Matthew.bat" and ran it. The output was:

Code:

Hello
Press any key to continue . . .

My code works even if the file path contains a space.

The file name "$ Matthew.bat" works.
The file name "$Matthew.bat" does not work.
The file name "%Matthew.bat" works.
The file name "@Matthew.bat" works.

That is baffling.

Code:

:: Clean Up the WinSxS Folder

@Echo off

(Net session >nul 2>&1)||(PowerShell start """%~0""" -verb RunAs & Exit /B)

I think FreeBooter's code can be simplified as below:

Code:

For /f "tokens=2 delims==" %%# in (
'wmic path Win32_OperatingSystem get BuildNumber /value') do (set /a WinBuild=%%#)
If %winbuild% LEQ 7601 (Goto :EOF) else (
Dism.exe /online /Cleanup-Image /StartComponentCleanup /ResetBase)

Dism.exe will be run as long as the OS is Windows 8 or above.

Code:

Set "SFC=%UserProfile%\Desktop\SFC_Errors.txt"

%UserProfile%\Desktop\ does not work if the desktop has been relocated: Move Location of Desktop Folder in Windows 10

The following works even if the desktop has been relocated:

Code:

For /F "usebackq tokens=3 " %%X in (
`Reg Query "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders" /v Desktop`) Do (
Set 👽=%%X)
For /F "usebackq delims=" %%Y in (`Echo %👽%`) Do (Set ❤️=%%Y)
Set "SFC=%❤️%\SFC_Errors.txt"
