- Rebooted into safe mode (same issue occurs)
- Attempted to restore to an earlier checkpoint (either an error occurs (unknown error 0x800700b7 or 0x8000FFFF) or, strangely, the operation doesn't appear to do anything, and rebooting I'm presented with the same available checkpoints)
- Checked disk for errors (none found)
Finally, I discovered this forum and downloaded and then ran FarBar Recovery Tool. The log output is attached below.
In the log, I did notice some interesting newly modified files in the WINDOWS directory (is-L87GL.exe). Also, when rebooting into safe mode, the last driver that is fully loaded before failure is CLASSPNP.SYS.
Thanks so much in advance for your help. If you need any further information, feel free to let me know.
