Vista - Should I Update To SP2?

I have it in Windows Update, but I wanted to ask you guys, is it worth it to do it? My computer is really only used for gaming and such, and I've heard it causes issues...

Also, if I installed it to 4%, then clicked 'cancel' do the 4% of files get installed, or at least do they not actually come into effect unless it's completely installed?

I have it installed & would recommend downloading it.

Vista SP2 is out

Hi DrKillPatient, in regard to your question "if i installed it to 4%" if you are meaning downloaded 4% & cancelled then no all that would have happened is a part file would have been created in Software Distribution which windows update should add to if you wish to continue with the download at a later date. If you did start the installation and then canceled it you may have problems in particular with drivers. During a service pack installation drivers are reinstalled so a cancellation could leave you with a problem driver. To check this go into control panel then Device Manager and you will see a yellow alert if there is a problem. If so you may be able to do a system restore (pre service pack installation) i do not know if this will work otherwise you will have to reinstall the problem driver. I hope your problem is simple and you were refering to only downloading 4%. All the best

I mean that I clicked Install in windows update, then cancelled it.
I did a system restore to a slightly earlier date immediately after just to be safe. Everything seems to be working fine.

I installed SP2 on 6/10/09 all is well so far, if I run utorrent and try to surf, IE8 and FF is very slow

I installed it when it came out and I dont have any issues.

I wouldn't recommend it - windows loads up a lot slower after SP2 in my case...

Different people have had different experiances. The only real way to know is to install it and try it out.
