From the Sharepoint Blog,
With many users both on campus and at home opting to upgrade to Windows 7, I wanted to pass along a tiny tidbit of information. Windows 7 is available in 2 different platforms, 32 bit and 64 bit. Users opting for 64 bit should note that there are 2 versions of Internet Explorer installed.
When using internet Explorer, you should make note to use the link that says Internet Explorer, not Internet Explorer (64-bit). Using the 64 bit version can cause problems when accessing Sharepoint, like not being able to properly open Office files.
It’s been a while since I’ve posted something SharePoint related so here’s a quick tip that started on Twitter. One individual whom I follow was asking if there was a fix for the Explorer View in a document library over SSL for those using IE8. That is our setup, SharePoint accessed over SSL and I run IE8. I told her I usually have to authenticate to open the view and the transfer is typically slow. We received a follow-up tweet from @Hugheser saying to check the LAN configuration settings in IE.
You want to uncheck that first box if it’s enabled and you’ll see an a significant increase in transfer speed.
