Vista Blue Screen recovery issues

Imagine the following situation just happened to me:
I decided to try out Microsoft Netmonitor 3.1, compatible with Vista,
hooray. I downloaded and installed it. I tried to use it but I couldn't, I
admit that I know very little about networking. That's ok. But after a few
minutes, suddenly I got a blue screen. No problem, restart. Normal mode, why
not. It starts up, I try to remove the program, then blue screen again.
Restart. Normal mode again, startup, and after 1 minute, blue screen.
Perfect. Restart, F8-F8-F8-..., Load last working configuration. The same.
Ok. Restart, safe mode, system restore... well, there were NO restore points.
Vista decided to clean up the 5 GBs of restore points RIGHT NOW (no other
OSes were used since days, and none of them even sees Vista boot partition).
Then I tried to remove the program from safe mode. But Vista kindly told me
that it can't launch Windows Installer from within Safe Mode. Then what? How
can I uninstall it? Normal mode gives instant blue sceen, Safe mode doesn't
allow me to uninstall. What I actually did was that I started a Total
Commander, went to the system32\drivers folder, located the driver file of
Netmonitor, removed it, and rebooted. Then from normal mode, I uninstalled
Netmonitor and now everything's fine. Except that my filesystem hardly
survived the series of blue screens, I'll have to do some scandisks tonight.

After all, I really don't understand some things.
1. Why does Netmonitor give a bluescreen?
2. Why is it almost impossible to recover Vista from a simple incompatiblity
issue? Why isn't there an option like "interactive driver loading" or such?

Or did I do something wrong? Is there a way to survive these situations
without hacking into the system32 folder?
Thanks in advance.
