Something is stopping lots of things from running! It seems to be something to do with permissions, I can't install some programs, including , funnily enough, Permissions Analyser by Solarwinds and I had hoped it was going to be the first thing Windows Repair, repaired...Last week the strangest thing happened, Internet Explorer and 25-30 URL and program shortcuts disappeared off my desktop! I have no idea what happened there and search results although finding similar incidents were on machines with different issues to mine. Is there a way I could manually reset the permissions to default as your program does? (I assume). I have run most of the top Anti-virus and Rootkit programs off Bleeping Computer and nothing has shown up, have just run Hijack This and nothing major there either. On trying to uninstall Windows Live Mail, I receive the message "Error getting file security: C: Program Files (x86)\ GetLastError: 5. I have no idea what that's all about! I'll leave you with that for now but if you have more questions or need more info I will endeavour to provide. Just to let you know, I'm on the other side of the planet in New Zealand, luckily I'm a night-owl it's 3.45am here...
