【转】转移Package Cache文件夹,转移Windows Installer文件夹

详见http://blogs.msdn.com/b/heaths/archive/2014/02/11/how-to-relocate-the-package-cache.aspx

(注意：若Windows自动更新之后导致Windows installer文件路径找不到，可以在磁盘管理中，重新把installer的虚拟盘映射到C:Windows installer)

在CMD打开diskpart工具

diskpart

创建一个最大为16G空间的虚拟磁盘

create vdisk file="E:VHDCache.vhd" type=expandable maximum=16384

连接并创建分区

select vdisk file="E:VHDCache.vhd"

attach vdisk

create partition primary

格式化分区，卷名Package Cache，盘符P

format fs=ntfs label="Package Cache" quick 

assign letter=P

exit

拷贝Package Cache到刚创建的虚拟磁盘P中

robocopy "%ProgramData%Package Cache" P: /e /copyall /move /zb

...等待.....

mkdir "%ProgramData%Package Cache" 

echo y | cacls foo /s:"O:BAG:DUD:PAI(A;OICIID;FA;;;BA)(A;OICIID;FA;;;SY)(A;OICIID;FRFX;;;BU)(A;OICIID;FRFX;;;WD)"

查看P盘的GUID

mountvol 

并将Package Cache目录指向

mountvol "%ProgramData%Package Cache" \?Volume{xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}

卸载盘符P

diskpart

select vdisk file="E:VHDCache.vhd" 

select partition 1

remove letter=P

exit

开机自动挂载虚拟磁盘，并删除盘符

echo select vdisk file=E:VHDCache.vhd > E:VHDCache.txt

echo attach vdisk >> E:VHDCache.txt

schtasks /create /ru system /sc onstart /rl highest /tn "Attach Package Cache" /tr "%SystemRoot%System32diskpart.exe /s E:VHDCache.txt"

同以此方法，创建C:WindowsInstaller的虚拟磁盘

在CMD打开diskpart工具

diskpart

创建一个最大为16G空间的虚拟磁盘

create vdisk file="E:VHDInstaller.vhd" type=expandable maximum=16384

连接并创建分区

select vdisk file="E:VHDInstaller.vhd" 

attach vdisk

create partition primary

格式化分区，卷名Package Cache，盘符Q

format fs=ntfs label="Installer" quick 

assign letter=Q

exit

拷贝Package Cache到刚创建的虚拟磁盘Q中

robocopy "C:WindowsInstaller" Q: /e /copyall /move /zb

...等待.....

mkdir "C:WindowsInstaller" 

echo y | cacls foo /s:"O:BAG:DUD:PAI(A;OICIID;FA;;;BA)(A;OICIID;FA;;;SY)(A;OICIID;FRFX;;;BU)(A;OICIID;FRFX;;;WD)"

查看P盘的GUID

mountvol 

并将Installer目录指向

mountvol "C:WindowsInstaller" \?Volume{xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}

卸载盘符P

diskpart

select vdisk file="E:VHDInstaller.vhd" 

select partition 1

remove letter=Q

exit

开机自动挂载虚拟磁盘，并删除盘符

echo select vdisk file=E:VHDInstaller.vhd > E:VHDInstaller.txt

echo attach vdisk >> E:VHDInstaller.txt

schtasks /create /ru system /sc onstart /rl highest /tn "Attach Installer" /tr "%SystemRoot%System32diskpart.exe /s E:VHDInstaller.txt"
