Folder options control panel in Xp Home

[maxtbb]

With no warning, every program I try to activate now results in the
following response, "This file does not have a program associated with it for
performing this action. Create an association in the Folder Options control panel." I don't know what to do to rectify this new problem. Everything
worked very well before. I have no problem getting on-line and receiving/
sending E-mail. I did notice that at the same time as this problem arose, I
also get a yum.exe-Application Error stating, "The instruction at 0x77t83905
referenced memory at 0x00000001. The memory could not be "written.
Click on OK to terminate the program." This error appears as I initiate and
depart the internet. I have SBC DSL through Yahoo.

Do a system restore back to a date when everything still worked right.

glc. System restore is just another program that also cannot be initiated.
I've already attempted this earlier. Nothing in programs can be
activated by "clicking" on it. This also applies to everything previously
available in System Tools.

I also neglected to furnish the components I built into my "home-built."
