你是不是开启了NTFS的磁盘压缩?
下面是从网上找来的一个解决办法。
1) Boot to the recovery console (you should automatically get there after a few Blue Screen crashes)
2) Launch command prompt
3) Run the following command:
c:\windows\system32\compact.exe /U c:\windows\system32\drivers\*.sys
4) Reboot
5) As soon as you successfully boot, disable NTFS compression system-wide so that the CBS Scavenger does not reintroduce the issue again:
fsutil behavior set DisableCompression 1
6) Reboot again (so the DisableCompression setting takes effect)
另外,很可能这是Windows自身引起的BUG,所以可以给微软反馈下。
