The easiest way is to do a system restore…if you are using Windows XP. Restore back to before you installed IE7.
When it comes to Microshaft, I’ve learned if you installed a new program (from Microsoft), the restore dont always work. (Only reason I didnt mention it in the first place).
Also, FYI, Corporate version of Vista should come out this fall (in theory). Consumer version will be released next spring.
Beta version available for free from Microsoft (No updates, etc. available on this version… And it’s one massive download).
