10049 killed my SP3.

First of all why would you put an experimental OS on an active computer that you regularly use?

​You might want to actually read the thread before you jump in with a generalization like this....

Good for you, but how does that help his situation, at all?

It doesn't. What it does do is offer perspective for anyone else with an SP3 thinking of installing it.

I know what I'm doing. All my data is in the cloud, so nothing is lost. The only thing I really lose is time and I have plenty of that.

I'm sure you do, but using hyperbole llike it "killed" your SP3 warrants responses like this

I had the same problem with my SP2. Create a new local admin profile and log in with it. Delete your main profile. Recreate your main profile. When you log back on, it'll be fixed.
