How to uninstall patch
Uninstalling a patch using MSIPATCHREMOVE on a command line:- Msiexec /I MSIPATCHREMOVE= /qb Example:- Msiexec /I {0C9840E7-7F0B-C648-10F0-4641926FE463} MSIPATCHREMOVE={EB8C947C-78B2-85A0-644D-86CEEF8E07C0} /qb - Uninstalling a patch using the standard command line options:- Msiexec /package /uninstall /passive Note :- The /passive standard option is not an exact equivalent of the Windows Installer /qb option. This will uninstall only patch applied on any product.
