We are willing to test again Office Tabs. We had tested it before (version 11.0) but found time consuming issues when uninstalling Office Tabs through the Add/Remove software in Windows 10: the uninstall will not delete all the Office Tab folders at the hard disk C:Programs. It will not delete the Windows 10 registers from the office tab configurations. We had to delete them manually according to the attached procedure (pdf file attached to this post).
Please, let me know if you have fixed those uninstall issues in the last version of Office Tab.
