Hi, Folks:

If you ever run into a problem (which is rather common) with WinXP's
Sytem Restore displaying a blank calender, here's the fix.

System Restore Tool Displays a Blank Calendar in Windows XP

SYMPTOMS
When you run the System Restore tool on a Windows XP-based computer,
the calendar on the left side of the "Choose a Restore Point" window
is not displayed.
CAUSE
This behavior can occur if the file association for Hypertext Markup
Language (HTML) component (.htc) files is not in 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 behavior, verify that the following keys are in the
registry. If one of the registry keys is not present, create the key,
and then add the values that belong to the corresponding key:
HKEY_CLASSES_ROOT\.htc
Value name: Content Type
Value data: text/x-component

HKEY_LOCAL_MACHINE\Software\Classes\.htc
Value name: Content Type
Value data: text/x-component

HKEY_CLASSES_ROOT\MIME\Database\Content Type\text/x-component
Value name: CLSID
Value data: {3050f4f8-98b5-11cf-bb82-00aa00bdce0b}

Create a second entry with the following values:
Value name: Extension
Value data: .htc

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

HKEY_CLASSES_ROOT\CLSID\{3050f4f8-98b5-11cf-bb82-00aa00bdce0b}
\InProcServer32
Value name: Default
Value data: "C:\Windows\System32\Mshtml.dll"

Create a second entry with the following values:
Value name: "ThreadingModel"
Value data: "Apartment"

NOTE: This procedure assumes that Windows XP is installed in the
C:\Windows folder. Make sure to change C:\Windows to the appropriate
<windows_folder> if Windows XP is installed in a different location.

To merge all of the information at one time, you can copy and paste
the following text into a text editor, such as Notepad, and then save
it as a .reg file.

NOTE: You must copy all of the following text to ensure that this
procedure works as expected.

Windows Registry Editor Version 5.00

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

[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\\System32\\mshtml.dll"
"ThreadingModel"="Apartment""

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

After you finish the preceding steps, you can use the System Restore
tool. However, when you use the System Restore tool to restore an
earlier configuration, the registry fix is removed from the Windows
registry. To make sure that the problem does not occur again after
you restore the earlier configuration, repeat the preceding steps to
fix the System Restore tool, create a new System Restore point, and
label it to indicate that it contains the System Restore fix. After
you do this, you can use the System Restore tool at any time to
restore the System Restore point that contains the fix without
damaging the System Restore tool.

Also, Folks, if you have problems accessing SysRestore from desktop,
reboot in SafeMode. Click the System Restore link. Click the
Restore My Computer to an earlier time, next. Note: In Safe Mode, you
*may* need to navigate via your arrow keys and Enter key.

HTH.
