First, SP1 has a very significant performance enhancement and the code has been optimized. Interestingly, this SP1 still has Microsoft internal network share tags embedded with the update source code, such as:
\\winbuilds3\longhorn_SP1Beta1\longhorn_SP1Beta1

Although this information is of little use to us, it is useful to understand the file layout of Microsoft's internal publishing share.

The new situation is that the WINPE system is suspended from the CD. However, you can start GHOST from the CD for backup. In early January, the company bought a new HP laptop (I can't remember the specific mod

Another point to note is that the full PC Backup and Recovery tool is not included in Windows
