Until recently , on XP SP3, I asked to be prompted when updates were available, and occasionally did not install some (eg Silverlight which I dont think I use?) I have now been on W7 64 bit for a few weeks and updates are on full auto - so far no probs and unless you look you hardly know they have been installed. I think I will leave it on auto, but does anyone disagree?
John Just to add my own experience of W7, prior to getting a new laptop with W7 in November I had been happy to allow updates to download and install automatically. Then, when my new machine started via defaults to operate the same way I started to get freezes and crashes that were traceable to the updates. Sometimes the update had (partially?) failed or it was a driver issue. I discovered this by uninstalling the lot I was initially deluged with and installing them one at a time. Since then, and there aren't many, I look at the suggested updates and install them singly.
It's now 30 mins after my last posting and .... guess what? I'm currently on my Netbook as my laptop has frozen after downloading 2 important and one optional update. I'll probably be an hour or so sorting the bloody thing!
