Reading a registry value to a batch variable, handling spaces in value

Ah this is one of the annoying details about the for /f command. In order to read all the characters including the spaces with the * the previous token needs to be declared. tokens=2,* The functional reason is stated in the documentation.

If the last character in the tokens= string is an asterisk (*), an additional variable is allocated and receives the remaining text on the line after the last token that is parsed.

FOR Documentation

FOR /F "usebackq tokens=2,* skip=2" %%L IN (
    `reg query "HKLM\SOFTWARE\Microsoft\Microsoft SDKs\Windows\v7.1\WinSDKTools" /v InstallationFolder`
) DO SET sdkpath=%%M
