Upon the Restoration, the title of Baron Windsor, which had last been held by his maternal uncle Thomas, was called out of abeyance in his favour, on 16 June 1660.
However, he actually spent only three months in Jamaica: according to Samuel Pepys his abrupt return to England caused a good deal of comment.
His one notable achievement as Governor had been to order the attack by Sir Christopher Myngs on Santiago de Cuba.
He was appointed Gentleman of the Bedchamber to Charles II; in that capacity, he was sent in September 1678 with a crucial message to Danby to investigate certain allegations made by Titus Oates and Israel Tonge, thus setting in motion the Popish Plot.
He was succeeded by his grandson Other Windsor (his curious first name is a variant of Otho, a remote ancestor).
