  1. Have you found disabling Dr. Watson has improved your system’s performance? There’s actually a myth that says the Dr. Watson program logs all activities on Windows XP, Vista, and 7 machines and sends them to Microsoft. This rumor also says it can decrease the performance of your PC. Check out this small series of benchmarks using PCMark Vantage we conducted- The productivity benchmark did not show any noticeable differences when Dr. Watson was enabled or disabled. So it really doesn’t affect performance in Windows XP.

  2. I think it is depend on PC configuration.... according to my observation about 15% of people says that it slow-down the system performance.
