Partitions of new Windows 7 laptop systems-non-third-party tools

New Windows 7 laptop system partition-non-third-party tool tossing notes a new little black, T420, WIN7 system, ready to install dual system, ready to get a Centos, WIN7 keep it back for viewing the disk, as a result, we started a round-trip to WIN7 partitioning. Search for a WIN7 partition, the article of the various great gods came out, OK, according to do, very Easy to draw out a GB space on the C disk, but the C disk is still as high as GB. So GOOGLE did the following: 1. Allocated 10 Gb space on the unpartitioned disk, removed the paging file on the drive C, and moved it to the new disk. 2. Run the powercfg-h off command in CMD to disable sleep. 3. Some applications that are not used are deleted. After completing the above steps, we compress the volume on the disk. The tragedy found that the volume was compressed, but it only compressed dozens of MB! Then, the system prompts that the compression cannot be performed! In the middle of the night, we didn't deal with this damn shard. Instead, we went to bed. The next day, I had a hard time, and finally solved the damn partition. It turned out that the system was being restored, and the boys turned off the system to restore it, then you can find that the space you can compress is greatly increased. Summary: 1. compress the disk volume for the first time. This time, we should be able to compress half of the space. (I will not pay for it if I renew it online !) 2. Run the powercfg-h off command in CMD to disable sleep. 3. Disable System Restoration for all system disks. 4. format the compressed space, adjust the paging file to the newly formatted disk, and disable the paging file of the system disk. 5. restart the system. 6. compress the disk volume for the second time. Then you can see the space occupied by the system and the space that can be divided. After completing the above steps, we can smoothly reduce the space for the new drive C. I have allocated 50 GB, and the system partition should not be too small. XP may be 30 GB, which is enough, 30 GB is definitely not enough for WIN7. You should leave enough space.
