How do I stop a program from installing on my C drive?

“Is it possible to prevent any software from installing, in whole or in part, on the C drive using a command or a program?” This problem often arises when users find their C drive was occupied by lots of programs and files that were downloaded from the browser.

Normally, the C drive is the boot drive carried by your OS which will store huge amounts of information when your machine is running. So, C drive needs to have sufficient capacity to save all data to ensure your computer works well. If it’s full of the installed applications or big files, your PC will soon stick into a bad performance, lagging response, even blue screen caused by unknown malware probably bound to other programs.

However, C drive is the default storage location in Windows. If you want to stop programs to install automatically on the C drive, you’ll have to change some default settings. Lots of users don’t know where to find the settings and how to stop programs installing on C drive by changing those settings.

Don’t worry, in the next part, we’ll show you the details.

How to move installed programs from C drive to another drive

But, after stopping programs installed on C drive, what should you do to the installed programs? To move programs that had been installed on your C drive or the programs installed on the wrong drive, the situation will be more different. We all know moving a program can’t use “Copy” & “Paste”, it won’t boot after you changed the location. Thus, to ensure the moving will work and the programs can also boot as before, we highly recommend you AOMEI Partition Assistant Professional.

Its “App Mover” function allows users to transfer multiple pieces of software at one time. It can detect all related data files of the programs and move them together to make sure the programs can boot successfully after the moving. And you can move programs between drives with different file systems. Within easy steps, you can finish the moving or restoring operation.

Step 3. Check the applications you want to move, you can select single or multiple installed programs. Then select the drive where you want to move to, and click “Move”.

Tick App

Step 4. Read the prompts carefully, click “OK” and “Move”.

OK

Then, wait for the process.

Finish

After the moving, your C drive will release more free space, and if you wish to add more capacity to it, you can try “Allocate Free Space” or use the unallocated space (even it’s not right behind the C drive) to “Merge Partition”.

There is a “Move” button in Windows Settings (Settings > Apps > Apps and features), but it only applies to programs downloaded from Microsoft Store (Sometimes it couldn’t move programs from the Store). If the operation is forbidden, the “Move” button will be greyed out.
