I purchased Windows Upgrade 8 and ran Windows Update Assistant on existing windows 7.
However, It is asking me to uninstall Intel Wireless bluetooth, as it is not compatible with windows 8. I did just that and in spite of uninstalling it successfully, it is giving a message "Manually Uninstall". I dont know what this means? is it successfully uninstalled or not, and if not how do I uninstall it completely.
I posted this on Microsoft forum also and found many users are facing this issue. Noone from Microsoft has answered there.
I have tried CCleaner, Microsoft fixit and other tools but still no help.
