As with any other 'software update' remember 'update' is only a word - a more honest word would often be 'afterthought'.
Point being, while these 'afterthoughts' are occasionally helpful to protect you from vulnerabilities, they can cause new problems too. As often as not, the original authors of the software have moved on to new pastures, so those writing the afterthoughts are not even terribly familiar with the code they are 'fixing', one reason why ancillary problems are so common after 'updates'.
For spurious driver updates I'd strongly agree, if it is working leave it alone, it may not work any more after the 'update'. If you must update, if at all possible, make sure you have some means of restoring the previous version before updating.
