Dear All,

I saw 94 alerting regard "Windows Update" on my Server 2008 R2..

Each update has own codes, but i don't know which code applying for?

Could you please point me where can i understanding or learning about update code?

As We are IT, Should we need to update windows all available every time when it alert? 

Please give me idea..I am sorry i am learning about that too.

Best regards,

Here is a start.

For a specific error code you can always search for it and generally you can get the explanation from Microsoft website.

And for Windows Updates, we always recommended users to keep their operation systems up-to-date. Some updates are critical which could help you fixing potential issues or attacks.
