After upgrading to Windows 10, working with tech support, upgrading DP+ to 5.2, and finally, reverting back to Windows 7, I would say, do not upgrade to Windows 10 on a DataPage+ computer, unless you do not need, want, or care about, the following functionality:
DataPage+ 2011 and 5.2- printing to PDF will not let you select text to copy.
DataPage+ 5.2 only- printing to PDF for Mixed Reports (where you are mixing portrait and landscape types) will print only in a single orientation, truncating landscape pages as if printing on portrait, or truncating portrait pages as if printing on landscape.
Neither are truly show stopping "enhancements", but they are annoying.
There are some other "features", dealing with upgrading from DataPage+ 2011, and/or from SQL 2005 to SQL 2008. If you are planning upgrades, and would like to know more, I can help answer your questions.
