AppName: mshta.exe AppVer: 6.0.2600.0 ModName: unknown

I receive the following erro window whenever I click
on "change the way users log on or off" from Control
Panel:

Microsoft (R) HTML Application host has encountered a
problem and needs to close. We are sorry for the
inconvenience.

The "For more information about this error. click here"
message returns the following detail":

AppName: mshta.exe AppVer: 6.0.2600.0 ModName: unknown
ModVer: 0.0.0.0 Offset: 00000000

I would very much like to utilize the fast user switching
capability of XP again on this desktop. Any suggestions
that would point me in the right direction would be
greatly appreciated. Thanks in advance.

I performed the set of operations you provided. I also checked the ( \\windows\system32\mshta.exe & \\windows\system32\dllcache\mshta.exe file directory version properties after the operation.

Versioning data one would expect to see (e.g, Microsoft, 6.00.2600.0000 (xpclient.010817-1148, etc.) displayed from each file's property pages. I rebooted my system after checking the properties

I unfortunately continue to recieve the very same error after I click upon the "change the way users log on or off" link from the Control Panel's "User Accounts" page. The error detail returns with the very same message I identified in my initial posting's subject line

Thank you in advance for whatever additional feedback you might be able to provide. Thank you also for having replied to my initial request for help
