Win 7, Home Premium, 64 Every time I reboot my machine I get an Event 3, Kernel-Event Tracing Error: "Session "UBPM" stopped due to the following error: 0xC0000022" and a companion "Session "Eventlog-Security" stopped due to the following error: 0xC0000022". All that I have found out is that UBPM is the Unified Background Process Manager and is used as necessary for certain tasks. So far I have not experienced any problems but maybe I just haven't done something that will require it. This started when I had a data drive (not same drive as C) begin to fail and cause problems with windows booting. Once I replaced the data drive Windows booted ok, but with some odd problems as this and including Event 25, volsnap errors which I have posted in another thread. Would appreciate some help in resolving this problem. Thanks.
