followed tutorial turn off windows features but wont finish

[billybellfoot]

hi i am following one of the tutorials to improve vista performance

i im performing the turn off windows features

i unchecked windows meeting space as i dont use it and games solitaire etc

clicked ok and message appeared may take several mins to cxomplete that was 30mins or more ago and still not finished? also the little progress bar is not filling up with green or even moving side to side as it does normally?

is this ok or is something not right?

thanks
