You create a folder called "Program" in the root of the volume hosting the Windows NT installation (boot partition). When you delete or rename it later, a dialog box comes up:
This change may impact one or more registered programs. Do you want to continue?This message appears even though no applications are installed in this folder.
If you click Yes, applications installed under the Program Files folder may not be usable anymore because the registry location will point to the Recycle Bin instead of the correct location. The application will not load for registered extensions and it cannot be started as an OLE or COM server anymore. You can still start the application through a shortcut to the executable or by double-clicking it in Explorer. The problem will happen with any path where the folder name matches the directory containing an application. For example, on the German version of Windows NT, the folder C:\Programme\Windows can cause this problem in conjunction with the folder C:\Programme\Windows NT.
Another symptom of the same problem occurs when the root folder contains a file named Program or an executable file with a base name of Program (such as C:\Program.exe). If this is the case, all the programs under the C:\Program Files folder with paths that do not contain quotation marks stop working.
On all Rename and Delete operations, the shell checks the files involved against the registry of all installed applications. If the path to the application executables contains spaces, the entry should be placed into the registry with double quotation marks around it because these entries can also contain command-line parameters.
However, many applications do not use quotation marks when adding the registry entries during installation. The parser, on the other hand, relies on those quotation marks to work correctly.
This means that the parser will read the string "C:\Program Files\Windows NT\Accessories\Wordpad.exe" as if it were the application C:\Program with the parameters Files\Windows and NT\Accessories\Wordpad.exe. Hence, it will display this warning when you try to delete or rename the C:\Program folder. It will also later change the path in the registry to the Recycle Bin or the new name for C:\Program.
If you have a file named C:\Program, the problem occurs when the shell tries to start a program with a path that does not contain quotation marks because the file produces a match against C:\Program, which is the first part of the full file name.

The English-language version of this fix should have the following file attributes or later:
Date Time Version File name Platform ----------------------------------------------------- 11/12/99 00:16 1.854.736 Shell32.dll Alpha 11/12/99 00:18 1.279.248 Shell32.dll Intel
After you apply this fix, the rename operation problems described in the "Cause" section no longer occur. The parser has been improved to check for these conditions.
However, because of the ambiguity of the path name, the second issue (having a C:\Program.exe or C:\Program file on the on the disk), cannot be solved. The only solution is to change the program in one of the following ways:
You can prevent the problem before it occurs with either of the following approaches:
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
