Did you try each option in the batch file, they do different thing as workaounds for the gwx icon issue.
Choices in the batch file:
1: Check Update Status
2: Quick-Method #1 [JC from answers.microsoft.com]
3: Quick-Method #2 [KevinStevens_845 from answers.microsoft.com]
4: Long-Method #1 [Yaqub K from answers.microsoft.com]
A reboot might be required, I forget. If after all methods have been tried, you might as well restart your machine - just in case it's that simple
It wasn't until the 2nd or third try, days apart, that my Win7 box finally got the icon
- it appeared after executing 2: Quick-Method #1
Also, did you follow the link in post# 8 to Cliff S's suggestion - some members had success that way.
