The reflector is “intelligent”, in that is only reflects COM activation data. To enable 64-bit/ 32-bit program interoperability through COM and other mechanisms, WOW64 uses a “ Registry Reflector” that mirrors certain registry keys and values between the 64-bit and 32-bit registry views.
To support the co-existence of 32-bit and 64-bit COM registration and program states, WOW64 presents 32-bit programs with an alternate view of the registry. For example, if the 64-bit version of Registry Editor is already running, type %systemroot%\syswow64\regedit -m to start the 32-bit version of Registry Editor. Note You must close the 64-bit version of Registry Editor before you can open the 32-bit version (and vice versa) unless you start the second instance of Registry Editor with the -m switch. Type %systemroot%\syswow64\regedit, and then click OK. To open the 32-bit version of Registry Editor, follow these steps:Ģ. There are no differences in the way you perform tasks between the 32-bit version of Registry Editor and the 64-bit version of Registry Editor. You can also view or edit 32-bit keys and values by using the 32-bit version of Registry Editor in the %systemroot\%Syswow64 folder. To view or edit 64-bit keys, you must use the 64-bit version of Registry Editor ( regedit.exe).
You can view or edit both 64-bit and 32-bit registry keys and values by using the default 64-bit version of Registry Editor. Many of the 32-bit keys have the same names as their 64-bit counterparts, and vice versa.
The registry in 64-bit versions of Windows is divided into 32-bit and 64-bit keys. Registry Editor : For 64-bit & 32-bit Windows
Missing or incorrect values in the registry can make the Windows NT installation unusable. You must use extreme caution when you use it to change registry values. On the right side, there are the values associated with the selected registry key. On the left side, there are folders that represent registry keys. This editor allows you to view or modify the Windows NT registry.The editor provides views of windows that represent sections of the registry, named hives. It is used to modify the Windows NT configuration database, or the Windows NT registry. Regedt32.exe is the configuration editor for Windows NT. You can migrate the Reg.dat database file to the Windows NT registry during the first logon to aninitial installation of Windows NT. Regedit provides a method for examining Reg.dat under Windows NT. Regedit.exe is a 16-bit application that is included in Windows NT for compatibility with previous 16-bit applications. The WOW layer resides on top of theVirtual DOS Machine (VDM). Reg.dat is used and maintained by Windows on Windows (WOW) and 16-bit Windows applications. It is also used by applications that support Object Linking and Embedding (OLE). The database contains information about 16-bit applications, and is used by File Manager for opening and printing files. The database is located in the Windows directory as Reg.dat. It is used to modify the Windows registration database. Regedit.exe is the registration editor for 16-bit Windows. Windows NT-based operating systems include two utilities for editing the registry, Regedit.exe and Regedt32.exe. This will make Registry Editor show up in Start Menu search as well. Or you can create a shortcut to regedit.exe and paste it in the Start Menu at %ProgramData%\Microsoft\Windows\Start Menu\Programs under the System Tools folder. So you can navigate to that folder and run the regedit.exe file directly. The main executable file of Registry Editor is located in the C:\Windows directory. Type regedit or regedit.exe or RegEdt32.exe and press Enter or click OK. Press + R keys on your keyboard, the Run dialog will appear. Regardless of the Windows version you have installed, this method will work: The registry also provides a means to access counters for profiling system performance. The kernel, device drivers, services, SAM, user interface and third party applications all make use of the registry. It contains settings for low-level operating system components as well as the applications running on the platform. The Windows Registry is a hierarchical database that stores configuration settings and options on Microsoft Windows operating systems.
