Free up drive space from the Windows installer folder
On my Windows 8.1 machine, the C:\Windows\Installer folder takes up more than 10 GB of space. Here are some techniques that can be used to free up C drive. This is a suggestion only that I tried and worked for me. Use at your own risk.
1. Make sure no installations are running on your machine. (You can check the task manager)
2. Copy using Windows explorer C:\Windows\Installer to another place (or you can use robocopy) (say D:\C_drive\Windows\Installer ).
robocopy C:\Windows\Installer d:\C_Drive\Windows\Installer *.*
3. Delete the folder C:\Windows\Installer ( rmdir /s /q C:\Windows\Installer )
4. Create a link to the folder in D drive.
mklink /D C:\Windows\Installer D:\C_DRIVE\Windows\Installer
Another way is to create a Junction Point for the folder Installer.
Another way is to compress the folder.Right click on the Installer folder , select properties, advanced, and select Compress option.
