Symptoms

When you run the System Restore tool in Microsoft Windows Millennium Edition (Me), the following behaviors may occur:
  • The calendar on the left side of the "Choose a Restore Point" window is absent.
  • The date on the title bar for the restore point list is Saturday, December 30, 1899.

Cause

These behaviors can occur if the file association for Hypertext Markup Language (HTML) Component (.htc) files is absent from the registry.

Resolution

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve this issue, check for the following keys, if one does not exist, create the key, and then add the values outlined below that belong to the corresponding key:
[HKEY_CLASSES_ROOT\.htc]
String Value Name: Content Type
String Value Data: text/x-component

[HKEY_LOCAL_MACHINE\Software\Classes\.htc]
String Value Name: Content Type
String Value Data: text/x-component

[HKEY_CLASSES_ROOT\MIME\Database\Content Type\text/x-component]
String Value Name=CLSID
String Value Data={3050f4f8-98b5-11cf-bb82-00aa00bdce0b}

Create a Second String Entry with the following Values:
String Value Name= Extension
String Value Data= .htc

[HKEY_CLASSES_ROOT\CLSID\{3050f4f8-98b5-11cf-bb82-00aa00bdce0b}]
String Value Name ="Microsoft Html Component"

[HKEY_CLASSES_ROOT\CLSID\{3050f4f8-98b5-11cf-bb82-00aa00bdce0b}\InProcServer32]
String Value Name = Default
String Value Data = "C:\WINDOWS\SYSTEM\MSHTML.DLL"

Create a Second String Entry with the following Values:
String Value Name="ThreadingModel"
String Value Data="Apartment"
To merge all the information at one time, you can copy and paste the following text into Microsoft Notepad, and then save it as a .reg file:
REGEDIT4

[HKEY_CLASSES_ROOT\.htc]
"Content Type"="text/x-component"

[HKEY_CLASSES_ROOT\MIME\Database\Content Type\text/x-component]
"CLSID"="{3050f4f8-98b5-11cf-bb82-00aa00bdce0b}"
"Extension"=".htc"

[HKEY_CLASSES_ROOT\CLSID\{3050f4f8-98b5-11cf-bb82-00aa00bdce0b}]
@="Microsoft Html Component"

[HKEY_CLASSES_ROOT\CLSID\{3050f4f8-98b5-11cf-bb82-00aa00bdce0b}\InProcServer32]
@="C:\WINDOWS\\SYSTEM\\MSHTML.DLL"
"ThreadingModel"="Apartment"

[HKEY_LOCAL_MACHINE\SOFTWARE\CLASSES\.htc]
"Content Type"="text/x-component"
