Registry Class for VBScript/MSHTA

Read/Write/Delete/Enumerate Keys and Values on Registry in VBScript/MSHTA using WMI.

Have you ever needed to read/write a 64-bit registry key in VBScript? Have you also ever needed to delete a key with sub keys?

The idea is to:

1. Provide x64 registry key support to VBScript\MSHTA.
2. Check if Key or Value exists on Registry. If Value or Key exists, returns it's type.
3. Delete key, sub keys and values.
4. Enumerate sub keys.
5. Enumerate Values from key (and it's type).
6. Create/Set Value on Registry.
7. Create Key on Registry.

Requirements

Windows 2000 or later (95, 98, NT 4 with WMI Core 1.5).

For Windows 2000 SP4, apply Hotfix KB817478 to replace WMI stdprov.dll to dump HKEY_USERS properly.

In all cases, WMI must be running for this class to work. On NT systems (2000/XP/Vista), WMI runs as a service. In order for this class to function the WMI service winmgmts must be running. Also, DCOM Server Process Launcher DcomLaunch must be running.

WSH Limitations:

• Cannot get unexpanded REG_EXPAND_SZ value if value name includes "\".
• EnumVals will include the key's default value only if it is not blank (WMI only returns it if there is content).
• WMI seems to often, perhaps always, return "REG_EXPAND_SZ" for plain string values, but it generally doesn't matter. A value that WMI says is "REG_EXPAND_SZ" can still be read or written as "REG_SZ", and when calling GetValue the Type parameter can be sent as "", leaving the GetValue function to handle the ambiguity.
• Windows 2000, 2003 cannot read REG_QWORD values, as it lacks GetQWORDValue() method.
• Cannot get REG_RESOURCE_LIST (type 8), REG_FULL_RESOURCE_REQUIREMENTS_LIST (type 10) values (you probably do not want them either).
• Cannot properly get invalid REG_DWORD values having non-4byte length.
• On Windows 2000, REG_SZ/REG_MULTI_SZ output could have bogus, memory-leak-ish values due to unknown bug in the system. (several occurrences when dumping the whole HKEY_LOCAL_MACHINE)

Note:

• Dumping full tree of HKLM could take significant amount of time with a high CPU load. (HKLM dump of Windows Vista yields ~160MB file)
