I haven't gotten any updates since March 30. I checked my muweb.dll, and it was version 7.6.7600.257, so I downgraded it to 7.6.7600.256 (suggested on this page) and rebooted, but I'm still not seeing anything. MGADiag.exe says the activation/WGA status is all good as well. I tried installing Microsoft Update, but this only offered Live Essentials and some other bloatware in the "optional" category. SP3 and IE8 are both installed.
I'm not getting any errors, and I don't have any updates hidden; it's just not offering up any updates for me. Says the system is up to date.
Has anyone else seen this problem?
