Are you tired of Exchange 2007 Rollups taking 1h + to install, even on high end production servers? Don't panic, there's a possible workaround - disable the certificate revocation check in Internet Explorer. Yeah, you heard right.

 It can be found in the Internet Explorer options, see screenshot below:

Doing this brought my RU5 install time down to around 10 minutes instead of approx one and a half hours.

Hope you find this usefull!
