Windows Service packs are huge in size most of the time and if you windows drive is already running out of space it is best that you change the location where windows store the service pack setup files. By default the setup files are downloaded in system drive and lack of space will not allow you complete installation. Follow the steps below to set up a new path or change it :
- Launch the Group Policy Editor ( gpedit.msc in your run window )
- Navigate to Local Computer Policy > Computer Configuration > Administrative Templates > System
- Look for configuration item which says Specify Windows Service Pack installation file location.
- Enable it and specify a path, preferably to a different partition which has lot of free space.
- Another advantage is you can copy the service pack setup files from here and deploy it in any other computer without downloading again.
