reg QUERY /?: Displays the value of the registry value Version ....

Here is a detailed technical description for each example: Example 1: Exact path:

REG QUERY "HKLM\Software\Example"

This command retrieves information from the HKLM\Software\Example registry branch. It displays all subkeys and values ??in that path. Example 2: Path with quotes:

REG QUERY "HKLM\Software\Example with spaces"

This command is identical to Example 1, but displays the registry branch "HKLM\Software\Example with spaces". The use of quotation marks allows paths with spaces to be correctly interpreted. Example 3: Check permissions:

REG QUERY "HKLM\Software\Example" /v ValueName

This command checks the permissions for the registry branch "HKLM\Software\Example" and displays the value named "ValueName". Example 4: Filtering results:

REG QUERY "HKLM\Software\Example" /s

This command not only displays the information in the specified path, but by using `/s` it also recursively displays all subkeys and values ??in that path and its subkeys. Example 5: Check data type:

REG QUERY "HKLM\Software\Example" /v ValueName

Here, the data type of the value named "ValueName" is displayed in the registry branch "HKLM\Software\Example". Example 6: Avoiding spaces in the value name:

REG QUERY "HKLM\Software\Example" /v "Value with spaces"

This command displays the value named "value with spaces" in the registry branch "HKLM\Software\Example". Quotation marks are used to correctly interpret the value name with spaces. Example 7: Finding parts of the path:

REG QUERY "HKLM\Software" /k /s /f "Example"

This command searches for parts of the path that contain the text "Example". The `/k` and `/f` options are used to search for subkeys only and filter the text. Example 8: Check the options:

REG QUERY /?

Help for the `REG QUERY` command is displayed here, which contains a list of available options and how to use them. Example 9: Pay attention to quotation marks when specifying paths:

REG QUERY "HKLM\Software\Example with spaces"

This command repeats Example 2 and again displays the registry branch "HKLM\Software\Example with spaces". This emphasizes the importance of using quotation marks on paths with spaces to ensure correct interpretation. There are a few important points to note when using the `REG QUERY` command in the Windows Registry:

Microsoft Windows [Version 10.0.19045.3693]

REG QUERY KeyName [/v ValueName | /ve] [/s]

  KeyName    [\Machine\]FullKey
    Machine - Name of remote machine,  omitting defaults to the current machine
         Only HKLM and HKU are available on remote machines
    FullKey  - in the form of ROOTKEY\SubKey name
         ROOTKEY  [ HKLM | HKCU | HKCR | HKU | HKCC ]
         SubKey  - The full name of a registry key under the selected ROOTKEY
  /v  query for a specific registry key   
         ValueName  - The name, under the selected Key, to query
         if omitted, all values under the Key are queried
  /ve query for the default value or empty value name <no name>
  /s  queries all subkeys and values

Examples:

  REG QUERY HKLM\Software\Microsoft\ResKit /v Version
    Displays the value of the registry value Version

  REG QUERY HKLM\Software\Microsoft\ResKit\Nt\Setup /s
    Displays all subkeys and values under the registry key Setup

There are a few important points to note when using the `REG QUERY` command in the Windows Registry: 1: Exact path: - Make sure the path provided is accurate and correct. Errors in the path can lead to unexpected results. Example:

REG QUERY "HKLM\Software\Example"

2: Quotes for paths with spaces: - If the path contains spaces, enclose it in quotation marks. This is important to ensure that the path is interpreted correctly. Example:

REG QUERY "HKLM\Software\Example with spaces"

3: Check rights: - Make sure you have the necessary permissions to access the specified registry key. Administrator rights are often necessary. Example:

REG QUERY "HKLM\Software\Example" /v ValueName

4: Filtering results: - Use options like `/v` for displaying values ??or `/s` for searching subkeys to filter the results. Example:

REG QUERY "HKLM\Software\Example" /s

5: Check data type: - Check the data type of the value you are querying to ensure you are getting the correct information. Example:

REG QUERY "HKLM\Software\Example" /v ValueName

6: Avoiding spaces in the value name: - When querying values ??with spaces in the name, enclose the value name in quotation marks. Example:

REG QUERY "HKLM\Software\Example" /v "Value with spaces"

7: Finding parts of the path: - You can search for parts of the path using the `/k` parameter. Example:

REG QUERY "HKLM\Software" /k /s /f "Example"

8: Check documentation: - Consult the help (`/?)` for the `REG QUERY` command to understand the available options and how to use them. Example:

REG QUERY /?

It is important to be extremely careful when working with the Windows registry as improper changes can lead to serious problems. Before making any changes, always create a backup and read the official documentation carefully.
