help with update manager

[baker`]

i am a new ubuntu user and im liking it very much so far :D
the update manager keeps popping up and im not sure which updates are necesarry and which i could do without, there seems to be alot of library updates. i am only hesitant to install them all because it is about 220MB in total and i am running ubuntu using wubi with limited storage.

is there any guides to the update manager and updates on this forum?
if not could you please advise me which ones i should choose :)

thankyou so much in advance.

Best way is to install all updates because they are there for reason.If you don´t want to upgrade some package go to the synaptic find package you don´t want to upgrade mark it and in package tab select lock version.This way you can stop Open office or other packages to be upgraded.You don´t want to do that with libraries,because not upgrading them can affect performance of some packages.
