Using the VirtualRegistry Fix
Applies To: Windows 7, Windows Vista
This section includes information about using the VirtualRegistry compatibility fix, including the associated issues, intercepted APIs, the available command-line options, and usage.
VirtualRegistry
The VirtualRegistry compatibility fix is one of the most commonly used fixes and can be used to:
Redirect a registry key
Spoof the existence of a registry key, including its value
Expand keys of the REG_EXPAND_SZ type to return to the REG_SZ type
Remove leading "\" characters from registry keys
Add the MAXIMUM_ALLOWED security attributes to all registry keys
Adjust the parameters of the QueryInfoKey to match those in Microsoft Windows® 95
Enable the deletion of keys that have subkeys, to match the behavior of Windows 95
Protect registry values and keys from deletion
Enable customized triggers to occur when a registry key opens
Investigating the Issue
Registry-related issues that can be resolved by applying the VirtualRegistry compatibility fix can be detected by using registry monitoring tools. The most frequently used tool is the Sysinternals' Process Monitor, which enables you to review the registry keys that are accessed prior to a failure, so that you can begin to predict potential fixes.
Important
In a few cases, the command-line options are named after the first application in which the issue was located. It is possible that additional applications can use the same fix, if they are experiencing the same type of issue. Microsoft has made every attempt to be accurate in this section. However, there are cases where multiple fixes exist for the same issue and there is a potential for some issues to no longer be valid and, therefore, no longer require the fix.
Intercepted APIs
The following table provides a list of APIs that are intercepted by the VirtualRegistry fix.

| RegCreateKeyA / RegCreateKeyW | Makes a virtual call to create a registry key. |
| RegCreateKeyExA / RegCreateKeyExW | Makes a virtual call to create a registry key. |
| RegEnumValueA / RegEnumValueW | Makes a virtual call to enumerate the values of a registry key. |
| RegEnumKeyA / RegEnumKeyW | Makes a virtual call to enumerate the subkeys of a registry key. |
| RegEnumKeyExA / RegEnumKeyExW | Makes a virtual call to enumerate the subkeys of a registry key. |
| RegQueryInfoKeyA / RegQueryInfoKeyW | Makes a virtual call to retrieve information about a registry key. |
| RegSetValueA / RegSetValueW | Makes a virtual call to set the value of a registry key. |

Fixing Your Code
We recommend the following modifications to fix your application's registry-related issues:
Modify your application so that it does not access undocumented portions of the registry to look for features and versions. Undocumented areas, which include the registry, will often be modified by newer versions of the Windows operating system.
Modify your application so that it performs its version checks by using the GREATER THAN or EQUAL TO operators, instead of an equality comparison.
Modify your application so that it gracefully handles the situations whereby a key is not found or access is denied.
