Vista PC Problems

As always I have a few grumbling problems with my Vista PC. However, they are getting slightly more annoying recently. For some reason, I currently have a Dreamweaver problem which means I have to delete a wincache data file each time I want to load it successfully.

The other problem is Outlook 2007 keeps wanting to corrupt itself. i have to keep rebuilding it with scanpst.exe. Currently each time I'm logging into my mail account it is deleting all the email of the mail servers. So on one email account alone it is downloading 450 emails each time it logs on every 15 minutes and I have to go through and clear them out again - multiply that across several email addresses it is getting a bit laborious. This Outlook problem was on top of the fact it was refusing to close a server connection and me have to start task manager each time and crash outlook so it would move on to the next email box. In fact, since starting this paragraph, the repair hasn't worked so my email is being rendered useless.

It also seems that doing upgrades to things like Safari, Skype etc entails wiping them off my machine and then doing a fresh install for it to work as Vista permissions doesn't let me do it otherwise.

My linux machine would be ok except I've forgotten the log in password so cannot currently get in. I have downloaded a page of linux instructions to overcome it - but its not top of my list....
