Over at ZDNet, I’ve just posted a description of the new Reliability Monitor tool in Windows Vista Beta 2. (Go read Watching Windows Vista Decay for all the details.)
According to the System Stability Chart at the top of the Reliability Monitor, my notebook has deteriorated alarmingly in the past four weeks, going from a perfect 10 rating to a mediocre 1.70. See for yourself:
The trouble is, this system isn’t particularly unstable. Instead, it appears that the System Stability Index itself is inaccurate. As I point out in the ZDNet piece:
This is a crude measurement, to be sure, and it’s misleading as well. The problems I’ve been experiencing (and which are logged in detail in the Reliability Monitor) are pretty much the same bugs, in Windows and in application software, occurring repeatedly, which is what you expect from a beta. So the inference that the system is somehow getting much less stable over time may not be accurate. In other words, my system stability was never a 10, and it’s certainly not a 1.70 now..
If you’re beta-testing Windows Vista, I’d like your help in assembling a dataset of Reliability Monitor readings. Open Reliability Monitor and make a note of the first date in the chart and the current Stability Index. (Click Start, Control Panel, System and Maintenance, Performance Rating and Tools, Advanced Tools, Open Windows Diagnostic Console. Or you can just click Start, type Perfmon in the Search box, and click the Perfmon shortcut when it appears.)
Post the date and the Index number and any additional subjective comments you have about Vista’s performance in the comments section below. Thanks!
