Uninstall completely all versions of MS SQL in our computer

We want to uninstall, delete and remove all traces of MS SQL2008.  We noticed that the Uninstall Programs in Control Panel has over 20 apps installed of MSSQL (including a 2012 version):

sqls


Please advice how to uninstall MSSQL, which should we "right-click >> uninstall" first, etc.

If I am not mistaken, all you need to do is load the respective media (SQL 2008/2012, etc) and it will have an option to repair or remove the SQL Server instance. It will take care of uninstalling all the features that were initially installed when installing the respective instance.

Uninstalling from Add/Remove has the risk that it may be done out of order or it might miss a few components.
janaAuthor Commented:
But the media are the actual downloads from Microsoft (all MSSQL installed are Express versions).  Do you mean run the installs again?

If you have SQL Server express, this approach won't work. Please follow the instructions in the MSDN documentation [https://msdn.microsoft.com/en-IN/library/ms143412.aspx] and you should be all set.

Ok, thanx for all comments, will try.
janaAuthor Commented:
Read the links, why does it recommend prior uninstall to "Delete the local security groups"? What's the purpose?
Arifhusen AnsariBusiness Intelligence Developer and AnalystCommented:
Did you try to uninstall in directly from the Uninstall program?
janaAuthor Commented:
There is no uninstall program found; we uninstalled via Control Panel as recommended by the links provided.

But why does the links recommend prior uninstall to "Delete the local security groups"?
janaAuthor Commented:
We just uninstall SQL 2008 via Control Panel.  There still SQL 2012 and other non-2012 such as 'Server Compact', 'Data Tools', 'Database Publishing', etc. (see pix below)

Any specific order to uninstall the still installed SQL apps? Which should we uninstall first, second, etc.?

>>"why does the links recommend prior uninstall to "Delete the local security groups"?"

because, typically, a dbms server will have special security arrangements - and the instructions are making sure you don't forget to clean-up the security.
janaAuthor Commented:
Thanx!

What about our entry ID: 41387397? About the still present SQL 2012 and other non-2012 SQL components even though we ran the process of uninstall thru add/remove?

Please Advice on that?
PortletPaulEE Topic AdvisorCommented:
Sorry. I have no experience with that uninstall problem and hence cannot provide further assistance. I offered an opinion on your "subquery" regarding security - that is all.
janaAuthor Commented:
Understood.

Thank you.

Hi,

We are almost done completely uninstalling all MS SQL products.  The SQL2008 was uninstalled as recommended by EE successfully.  However there are 2 types of MS SQL products still installed:

There still SQL 2012 products (see pix belos)
ALso the other non-2012 such as 'Server Compact', 'Data Tools', 'Database Publishing', etc. (see pix below)
(haven't unistalled these because maybe there were part of the Windows 10 upgrade?)

This is what we have at this point:
sqlfinails

Note:
We can go and uninstall all of them, but as said above, the version that has no 2012 we dodn't know if there are part of another Windows 10 installation and important for that.

Please advice.

Start by uninstalling MSSQL 2012 Express LocalDB and then the Compact versions.
After that uninstall MSSQL Data Tools and what stays are only client tools and you'll need to uninstall them one by one.

Thanx!  Will do!
janaAuthor Commented:
Worked!  After uninstalling, no SQL apps is found in Windows 10 Uninstall Programs windows.

Thanx!
