instances of MSDE

I can install instances of MSDE without any problem. But
for some reasons the password (or the instance) get
corrupted after I try to upsize a table from MS Access to
an existing database in MSDE (I'll stop doing this).
But now I have multiple instances which I would like to
clean up. Does anybody know how to uninstall them?
Thanks

Hi ,
You can use the following information to uninstall msde.
A)Remove the following registry:
1) Remove the following ID_Number from your MSDE 2.0 instance
HKEY_CLASSES_ROOT\Installer\Products\ID_Number
-- It has key value name 'ProductName' which displays the instance name.
For example, "ProductName" = Microsoft SQL Server Desktop Engine
(MYINSTANCE)
2)If you had patch applied on this MSDE 2.0 instance, you need to remove
ID_Number
for that MSDE 2.0 instance:
HKEY_CLASSES_ROOT\Installer\Patches\ID_Number
3) For MSDE 2.0 Default instance, remove
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer
For MSDE 2.0 named instance, remove
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL
Server\Your_instance_name
4)If you have the following key points to MSDE 2.0 productGUID, then remove
the
InstanceComponentSet.x
For example, HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL
Server\Component
SetInstanceComponentSet.x
-- For example, InstanceComponentSet.1 the has value matching the
productGUID of
sqlrun01.msi.
5)Remove :
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Uninstall\Produ
ctGUID
-- the Product GUID which refers to your MSDE 2.0 instance.
6)Remove the Sql server service key:
For MSDE 2.0 default instance, remove
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\MSSQLServer
For MSDE 2.0 named instance, remove
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\MSSQL$Your_Instance_Nam
e
7)Remove the Sql server agent service key:
For MSDE 2.0 default instance, remove
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\SQLServerAgent
For MSDE 2.0 named instance, remove
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\SQLAgent$Your_Instance_
Name
B)Remove the MSDE 2.0 instance data and program install directory:
For example, G:\Program Files\Microsoft SQL
Server\MSSQL$Your_instanceName\data
For example, G:\Program Files\Microsoft SQL
Server\MSSQL$Your_instanceName\binn
Now rerun the msde setup from the command prompt
