At the suggestion of others on this forum, I decided to give Windows 7 a try through bootcamp on my iMac (specs in signature) using this downloadable 30 day trial of Windows 7, and stretching that trial out much longer than 30 days using this guide. I'm nearing the end of the maximum number of days I can extend this trial, so before I make a decision on whether I actually purchase Windows 7 first, I want to know a few things... A) How thoroughly can I erase the 300 GB of partitioned space I set aside for Windows 7? For example, can I format that part of the hard drive so that I'm forever rid of any information from Windows 7 and any viruses/malware/trojans I may or may not have downloaded? B) If I purchase a full version of Windows 7, would I loose any of my data on my bootcamp partition? C) If I don't upgrade to a full version of Windows 7, what happens to all the information on my bootcamp partition? D) How easily can information from my bootcamp partition seep into the rest of my computer's hard drive space? That is, if I unintentionally violated some copyright law (like extending the trial period like my second link details) or something on the bootcamp partition, could the rest of my computer's identity be compromised? Any and all responses are appreciated. Thank you!
