从去年 12 月开始，我无法创建任何卷影副本。使用卷影副本的所有操作（包括 Windows 备份、系统还原和在线磁盘检查）均失败。我的系统运行的是从 Windows 7 Home Premium 升级而来的 Windows 8 Pro，我的系统驱动器之前启用了 BitLocker，但最近已将其关闭。每当我尝试创建卷影副本时，都会失败，并且事件日志中会显示以下错误：
卷影复制服务错误: 在卷影复制提供程序 {b5946137-7b9f-4925-af80-51abd60b20d5} 上调用例程时出错。例程详细信息 EndPrepareSnapshots({xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}) [hr = 0x800706be，远程过程调用失败。]。
操作：执行异步操作
上下文：当前状态：DoSnapshotSet
xxxx 是每次都不同的内容，但其他内容每次都相同。事件 ID 为 12293，来源为 VSS。
我试了一下操作之后，有些写入器会超时，如下所示，在全新启动时，一开始没有任何错误。

答案1
昨晚尝试安装 Windows 几次但均未成功后，卷影副本又能正常工作了。我认为强制检查 C: 有所帮助。
PS 过了一会儿，问题又出现了。现在的原因是 SoftPerfect RAM 磁盘。我移除它们后，它又恢复正常了。
