One of the PCs I support has Office 2010 installed w/ W10 1909, no issues whatsoever. However, Microsoft will be dropping Office 2010 support on the 13th of October, 2020, but you could continue using it just like the previous Office Suites (2003 and up).My user seems to think there is a problem. She sent me some documents that were created in office 2010 (word and excel) and I opening them in office 2007 and win 10.
I think she will be fine.
