Hi Ringo,I don't know Investment Accounts, as I don't own any, but the latest Build for Windows 10 is Build 10586.753 not 545. You might wish to open Settings and then Update and security and check for Updates.
q,lurker,I am using Windows 10 Version 1607 for x64-based Systems (KB3211320) as of 1/24/17. Not sure where I got the info 10.0.10586.545.My last sentence is also in accurate. Starting value of account (A), appears to be correct for 1/1/16 in the portfolio view. The starting value in the investment performance on 1/1/16 is way undervalued generating a performance of 53%. My guess is it should be more like 5-7%. The issue seems to be that the portfolio value on 1/1/16 is not being ported to the starting value of the performance output.Since there doesn't appear a way for me to validate how the starting value was created in the performance report I do not know what else to do. I have used file operations to validate the file.Thanks for the response, will look for additional input.
