Regsvr32 I Shell32.dll
Yvone Samiento
It pops all over the net as a magic pill to solve all kinds of problems, from file associations to desktop icons to enabling camera preview to making coffee (ok, maybe not coffee). What is it actually for and how should, or shouldn't, it be used?
Some (dll) files in Windows need to be registered in order to be used by other applications, and by parts of the operating system itself. Shell32.dll is a critical system file that is used everywhere by Windows itself, and by other programs. When you install Windows, it registers all the files it needs, and that registration is basically writing some stuff in the registry (although it can do more than that).
Sometimes, for various reasons (malware, etc) these registry settings get deleted, corrupted, overwritten, etc. This may lead to numerous problems like the ones you are describing (file associations, desktop icons, etc). When that happens, one of the things you can try is repairing the registration of certain DLLs. That is done by re-registering the DLLs, so those registry settings can be restored, re-written.
If we are to compare, this is the DLL equivalent to reinstalling an application. For example, if MS Office starts to malfunction and not work properly, you can try reinstalling it. If some stuff goes wrong in Windows and it's related to shell32.dll, you can try to re-register shell32.dll.
regsvr32.exe is a tool included in Windows that can register and unregister DLL files. In order to use it, you pass the name of the DLL you want to register/unregister, and some flags that specify what you want to do. regsvr32 /i shell32.dll is practically saying "Please register the shell32.dll file for me". This internally calls the DLLs' DllInstall function, and the DLL is registered again.

Regsvr32, which is known as Microsoft Register Server, is a Windows built-in command-line tool that can be used to register and unregister DLL files, ActiveX Control .OCX files, or such kinds of Object Linking and Embedding (OLE) controls files.
When you use regsvr32 to reg a DLL file, the information about the associated program files will be added to the Windows Registry. Then, the program can access the Windows registry to understand where the program data is and how to function.
3. Then, you need to type the regsvr32 command. Here is how to structure a reg DLL command in Command Prompt: regsvr32 [the name of the DLL file]. Take the shell32.dll file as an example. You need to type regsvr32 shell32.dll and press Enter to execute the reg DLL command.
For more information about the Regsvr32 tool, you can read the Microsoft official page: How to use the Regsvr32 tool and troubleshoot Regsvr32 error messages. In this post, you can also get some solutions for common Regsvr32 errors.
After reading this post, you can discover that it is easy to register a DLL file using Run or Command Prompt. You can just select one method according to your own situation. Should you have any questions, you can let us know in the comments.
I was able to fix the names (to show "My Computer" and "My Network Places") by making some changes in "hivecls.inf" and rebuilding the Registry (SOFTWARE hive), but still cannot get "My Computer" to work properly.
Any ideas? The only solution that comes in mind is to use old-style file open dialog (that shows only disks and "real" folders, but not "virtual" folders such "My Computer", "Desktop" etc), but it looks really ugly.
Sorry, I'm a bit confused with the version names/numbers. Version 2005 (which I refer to) is based on Windows Server 2003. But actually, the same problem exists in older versions, even based on Windows 2000 (a good example is Winternals ERD Commander).
Our problem is not locale-related (I think). We make WinPE image from US version of Windows, and don't need any additional keyboard layouts, non-US fonts etc. But I cannot understand what's going on with "Desktop" and "My Computer"
Have you registered any extra dll's, if I remember correctly they needed to be registered to work correctly. I can't remeber off hand which ones they are I want to say mycomput.dll, browseui.dll, and shell32.dll
Neither worked Probably, the DLLs have been registered successfully, but I still get an empty windows when double-clicking on "My Computer" in "file open" dialog. But as I already noted, in "Look in" drop-down box everything is OK -- i.e. I see the tree with "Deskop" in the root, "My Compuer" and all local drives there.
I had a similar problem with the variable indicator thing ('%MyBoxOJunk%' should be just 'MyBoxOJunk'). I believe the problem resides in the registry, variables defined incorrectly. I solved this by rebuilding, good to build near a drive root.
As for nothing in 'my computer', are you removing/upxing .dll files? Upxing saves negligable space in system32, and beware, it can strip more than icons. One the other hand, some enjoy life on the edge.

Adversaries may abuse Regsvr32.exe to proxy execution of malicious code. Regsvr32.exe is a command-line program used to register and unregister object linking and embedding controls, including dynamic link libraries (DLLs), on Windows systems. The Regsvr32.exe binary may also be signed by Microsoft. (Citation: Microsoft Regsvr32)
Malicious usage of Regsvr32.exe may avoid triggering security tools that may not monitor execution of, and modules loaded by, the regsvr32.exe process because of allowlists or false positives from Windows using regsvr32.exe for normal operations. Regsvr32.exe can also be used to specifically bypass application control using functionality to load COM scriptlets to execute DLLs under user permissions. Since Regsvr32.exe is network and proxy aware, the scripts can be loaded by passing a uniform resource locator (URL) to file on an external Web server as an argument during invocation. This method makes no changes to the Registry as the COM object is not actually registered, only executed. (Citation: LOLBAS Regsvr32) This variation of the technique is often referred to as a "Squiblydoo" and has been used in campaigns targeting governments.

I think something in my registry got messed up by a registry cleaner. Now i can't access the User Accounts, i'm on XP Home. I get the following error:
"wrong number of arguments or invalid property assignment". Can anyone help me to fix this? Thanks in advance.
I've registered here just to post BIG THANKS for this solution.
I also spent hours for searching for broken "Windows Explorer search function in XP" fix, tried many other solutions too, but this one actually helped.
It also fixed issue with User Accounts, where no accounts was shown when called from Control Panel.
I was ecstatic to find this post! I was able to register all but : regsvr32 /i mshtml.dll Got following message: "mshtml.dll was loaded but the DiRegisterServer entry point was not found. This file can not be registered". Any other suggestions?
Hi,
Try posting in your own thread and supply information about your PC and the problems you have been having, Quote this thread if you want. and read this above where you typed your post "This thread has been marked solved.
Perhaps start a new thread instead?"
if all those shit don't work then its time to restore your computer to previous sitting.
TO do that go to
Start->Programs->Accessories->System Tools->Restore System
Over here you will be give the steps to follow and if possible create a back up before going ahead.
This will work 100% but remember some temporary file can get deleted.
The shell32.dll error message could apply to any program or system that might utilize the file on any of Microsoft's operating systems including Windows 11, Windows 10, Windows 8, Windows 7, Windows Vista, Windows XP, and Windows 2000.
Do not download shell32.dll from a "DLL download" website. There are many reasons why downloading a DLL file that way is a bad idea. If you need a copy of this file, it's best to obtain it from its original, legitimate source.
