The built-in reg.exe<\/code> console tool lets you add, delete, export or save (as hive<\/a>) registry keys and values. When adding registry values using the reg.exe<\/code> tool, you may be wondering how to pass data with double-quotes or environment variables and add it to the registry literally.<\/p>\n

This article tells you how to create registry values passing double-quotes and environment variables (without expanding or resolving the folder path) using the reg.exe console tool.<\/p>\n

Add a registry value data with double quotes using REG.exe<\/h2>\n

Consider the following case. If you need to write to the (default)<\/code> by setting its data to \"d:\\my projects\\runx64.exe\"<\/code> with double quotes, you’ll need to escape the inner double-quotes using a backslash.<\/p>\n

Example:<\/strong><\/p>\n

REG ADD HKCR\\boxfile\\shell\\command \/ve \/t REG_SZ \/d \"\\\"d:\\my projects\\runx64.exe\\\" \"\\\"%1\\\"\"<\/pre>\n
\"reg.exe<\/p>\n
If you don’t escape the inner double-quotes around the data, such as:<\/p>\n
REG ADD HKCR\\boxfile\\shell\\command \/ve \/t REG_SZ \/d \"d:\\my projects\\runx64.exe %1\"<\/pre>\n
The command will complete successfully, but you’ll end up creating the following registry key\/value without double-quotes:<\/p>\n
\"reg.exe<\/p>\n
Example 2:<\/strong><\/p>\n
REG ADD HKCR\\boxfile\\shell\\command \/ve \/t REG_SZ \/d \"\\\"d:\\my projects\\runx64.exe\\\" -runmax \"\\\"%1\\\"\"<\/pre>\n
\"reg.exe<\/h2>\n
Add a registry value containing expandable string data using REG.exe<\/h2>\n
To add a REG_EXPAND_SZ registry value type and pass an expandable string exactly as given (without expanding the variable<\/strong>), you’ll need to use the caret ^<\/code> symbol with the %<\/code> symbol.<\/p>\n
Example:<\/strong><\/p>\n
REG ADD \"HKCU\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\User Shell Folders\" \/v Desktop \/t REG_EXPAND_SZ \/d ^%USERPROFILE^%\\Desktop<\/pre>\n
\"reg.exe<\/p>\n
If you don’t use the caret symbol, as in the following command-line example:<\/p>\n
REG ADD \"HKCU\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\User Shell Folders\" \/v Desktop \/t REG_EXPAND_SZ \/d %USERPROFILE%\\Desktop<\/pre>\n
The environment variable or expandable string is expanded or resolved to the folder path automatically, as shown in the following image.<\/p>\n
\"reg.exe<\/p>\n
Hope this article helped you pass complex command-line arguments involving double-quotes and expandable variables to the registry using the reg.exe<\/code> command-line.<\/p>\n","protected":false},"excerpt":{"rendered":"
