How do you determine its a 'WIN7' update.? My laptop is set for 3rd option.. 'notify me' when updates are available and I'll chose my time to install... yet. I'm still plagued by mysterious updates (Wi-Fi modem light going flat-out). When this occurs, all activity on my part is completely blocked. I thought the CPU might be saturated.. but NO, its not. I have a speedo type 'processor display'. It jumps around a bit, say 1%-40%, but no where near 100%. So, is it a 3rd party programme updated.? Regardless, it shouldn't, in principle, block me completely, whether its an hour or a day. Gnash gnash.
