Howto: Move Windows Update and Service Pack Files to Another Drive

September 16, 2010

Problem
Windows Server 2003 C partition is running out of disk space

Soultion
Move service pack and update files

Example
d:\1admin will be the path we are copying files to

Move the following files:

c:\windows\$NtUninstall*  to D:\1admin\Windows Update Files
c:\windows\ServicePackFiles to D:\1admin\ServicePackFiles
C:\WINDOWS\ie8updates to D:\1admin\ie8updates

Change these Registry keys:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup  = D:\1admin\ServicePackFiles\servicepackcache
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup = D:\1admin\ServicePackFiles
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup = D:\1admin

Also, I tell windows to stop downloading updates unless they are specifically requested!
