Windows 10 lets you to install programs and apps in a particular location on C: drive by default. Sometimes your system drive runs out of space when you install more programs or apps on it. Although the option appears to select the specific system drive whenever you install new programs yet there is another option to change default installation folder for all the programs in Windows 10. If you opt this method, there would be no need to select the drive while the installation of each program.
If you are running 64 bit Operating System, your system would contain 2 folders in C: drive for the installation of programs. All the 32 bit and 64 bit programs get installed on C:\Program Files (x86) and C:\Program Files respectively. Do keep in mind, if your system is 64 bit then any program whether it is 32 bit or 64 bit can be installed but if you are using 32 bit PC, 64 bit programs can’t be installed.
To Change Default Installation Folder for Programs in Windows 10
You can change default installation folder for new programs by making changes in Windows Registry. All the programs or apps which are already installed will be remained on same default drive i.e. C: drive yet the new programs will be installed on another drive (where you want to install that).
Follow the below given guide to change default system drive for installation of programs in Windows 10.
Type regedit in Windows search box and hit Enter key to launch Windows Registry Editor. When prompted with UAC, click on Yes.
Navigate the below given path in Registry Editor

Double click on them one by one and change the drive as per your requirement. You can see that C: drive is set to be as default. Replace the drive letter in the value data box. Hit OK key.
That’s it. Restart your PC to implement the changes. Now all the new programs and apps will be installed on new location. If you ever want to reverse this action, you can follow the same process to make changes.
