System Restore filter crashes with '0xC000009A'
Posted on 2009-12-30
Win XP SP3, new HP xw4600.
About once a week, the system freezes, requiring a restart. It is reported as Event ID 1, and "The System Restore filter encountered the unexpected error '0xC000009A' while processing the file 'CTT9069.tmp' on the volume 'Harddisk Volume1'. It has stopped monitoring the volume."
1) I suspect that the files (zero-length) such as CTT####.tmp are in use by some other [unknown] application at that moment. They are found in ~user/Local Settings/Temp.
2) Microsoft had a hotfix patch, but only for XP SP2, for a similar problem but the error code was '0xC000000D' (discussed kn KB888402).
3) Google searches only discuss the older SP2 treatment, or things like power supplies.
A. How might I find out what is using the file(s) CTT####?
B. A workaround would be to shut off System Restore completely, thouigh I believe that is a rash move, and only a workaround, not a fix.
C. Is it possible to tell System Restore not to look in the Local Settings/Temp directories? How?
What now, coach?
