I am wondering what is the best way to handle old questions and/or answers that may be out-of-date, but which I would like an up-to-date answer to? For example, one question I am looking at is about 5 years' old; however, computing can progress quite a lot in 5 years and I feel that some of the answers may be outdated.
Is it considered legit to post a duplicate of an old question, if I think it or its answers are outdated?
Alternatively, perhaps I could suggest an edit of the existing question; adding a note at the bottom to explain why I think it is out-of-date and ask if anyone can find an up-to-date solution?
Edit:
The example I am looking at is the following question:
How can I prevent Windows from overwriting GRUB when using a dual-boot machine
I feel that the accepted answer is out-of-date because I have a dual-boot machine with Windows 8/Linux and have disabled automatic Windows updates. However, I swear that it is wiping over GRUB every time I just boot into Windows (no update occurring). It is possible that more recent Windows updates may be becoming more aggressive towards GNU/Linux, compared to when these answers were posted.
