ASC - any version - is dangerous. Period.
Why is any version of ASC dangerous?
I have used it extensively for years with no problems.
I have used it on WinXP and Win7 and have had no problems with it at all.
Maybe the register cleaner that is built into it might seem dangerous, but I have tried other registry cleaners in the past, and I have found most of them very dangerous.
The ASC registry cleaner is the only one I have found that didn't wreck my registry.
(But then again, from what you have said, maybe it does, and I just didn't know it.)
Again I have used it extensively for years and have had absolutely no problems with it.
Some people claim they get BSODs from using it...I NEVER have.
But I have uninstalled it and it has NOT fixed my problem with installing SP3 for Office 2007.
So I will just leave things the way they are for now (since everything seems to be running fine) and not worry about the SP3 update.
If I need it that badly, I can go to WinXP on my dual-boot machine and use it there, since it did install there without any problems.
Again thank you guys for helping out.
