The fastest way depends on what you're moving and which operating system you use
Moving programs from one computer to another is not always a straightforward copy-and-paste job. Most software stores settings, registry entries, and dependencies in places Windows or macOS won't find if you just drag a folder over. The method that works best depends on whether you're moving between two Windows machines, two Macs, or crossing between operating systems — and whether the software came from an app store or was installed from a standalone file.
For most people, reinstalling from the original installer or app store is the most reliable path. But if you have dozens of programs or want to avoid re-downloading, there are faster options: built-in migration tools on Windows and Mac, third-party backup software, or moving the entire user profile. Each has trade-offs in speed, effort, and whether everything will actually work when you're done.
Key Takeaways
- Reinstalling programs from their original source (Microsoft Store, Apple App Store, or the publisher's website) is the most reliable method and takes the longest.
- Windows straightforward Transfer and Mac Migration Assistant can move multiple programs at once, but work best when moving to a newer machine of the same type.
- Portable programs and programs installed to a single folder can sometimes be copied directly, but most software will not run properly without reinstalling.
- Third-party tools like Laplink PCmover or Macrium Reflect can automate the process, but cost money and may not work with all software.
- If you have the original installer files or read links saved, keeping a list makes reinstalling faster than searching for each program again.
Reinstalling from the app store or publisher is the safest method
On Windows, programs installed from the Microsoft Store can be reinstalled on your new machine by signing in with the same Microsoft account. The Store keeps a record of what you installed, and you can read it again without paying twice. Open the Microsoft Store, go to your Library, and you will see everything you have ever installed there. Click each program and select Install.
On Mac, the same applies to programs from the Apple App Store. Sign in with your Apple ID on the new Mac, open the App Store, go to the Purchases tab, and reinstall what you need. Both stores handle licensing automatically — you do not need a product key or serial number.
For programs you bought or downloaded directly from the publisher (like Adobe Creative Suite, Microsoft Office standalone, or specialized software), you will need the original installer file or a read link. If you have the installer saved on an external drive or in cloud storage, copy it to the new machine and run it. If not, go to the publisher's website, sign in with your account, and read it again. You may need to enter a product key or serial number — check your email receipt or the original packaging.
This method is slower than copying files, but it guarantees the program will work correctly because the installer sets up everything the software needs to run.
Windows straightforward Transfer and Mac Migration Assistant move everything at once
If you are moving from one Windows machine to another Windows machine, Windows straightforward Transfer (on Windows 7 and earlier) or the Settings app (on Windows 10 and 11) can move programs, files, and settings in one operation. On Windows 10 or 11, go to Settings > System > About, scroll down, and select Transfer Your Data. This creates a backup of your programs and user files that you can restore on the new machine.
On Mac, Migration Assistant does the same thing. You can run it on the new Mac and point it to the old Mac over a network, or use an external drive as an intermediary. It copies programs, files, and system settings. Migration Assistant works best when both machines run similar versions of macOS — moving from an older Mac to a much newer one sometimes causes compatibility problems.
Both tools are free and built into the operating system. The downside is that they move everything, including settings and preferences you may not want to keep. They also take a long time if you have a lot of data. And if a program was incompatible with the new machine's operating system, the migration will copy it anyway, and it straightforward will not run.
Portable programs can be copied directly, but most cannot
Some programs are designed to run without installation — they are called portable programs. These are usually smaller utilities or older software. If a program is portable, you can copy its folder from one machine to another and it will work when ready. The catch is knowing which ones are portable. Most commercial software is not.
You can test whether a program is portable by looking at where it is installed. On Windows, open Control Panel > Programs and Features, find the program, and note the installation path. If it is in a folder like C:\Program Files or C:\Program Files (x86), it is almost certainly not portable and will not work if you copy it. If it is in a folder you created yourself, or in AppData, it might be portable — try copying it to the new machine and running the .exe file. If it starts, you are done. If it does not, reinstall it properly.
On Mac, most programs in the Applications folder can be copied to another Mac's Applications folder, but they may not work if the new Mac has a different version of macOS or different system libraries installed. Copying is faster than reinstalling, but if the program does not launch, you will have to reinstall anyway.
Third-party migration software automates the process for a fee
Tools like Laplink PCmover (Windows), Macrium Reflect (Windows and Mac), and Carbonite (Mac) can move programs and files from one machine to another automatically. These programs handle the technical details — they copy not just the program files but also registry entries, configuration files, and dependencies. They cost between $30 and $100 depending on the tool and whether you need to move multiple machines.
The advantage is speed and convenience. You run the software, point it at the old machine, and it does the work. The disadvantage is cost, and the fact that some programs still will not transfer cleanly — particularly older software, software tied to hardware, or software that requires a fresh license set up on the new machine.
Before you buy, check whether the tool supports the specific programs you need to move. Most vendors list compatible software on their website. If your most important program is not on the list, the tool may not be worth the money.
Moving between Windows and Mac requires reinstalling everything
If you are switching from Windows to Mac or Mac to Windows, you cannot move programs directly. Windows programs do not run on Mac, and Mac programs do not run on Windows (with rare exceptions like web-based software). You will need to find Mac or Windows versions of each program and reinstall them.
Before you switch, make a list of every program you use regularly. Then search for each one on the target operating system's app store or the publisher's website. Some programs have versions for both systems — Microsoft Office, Adobe Creative Suite, Slack, and most web browsers do. Others do not — some specialized or older software may only exist for one platform. If a program you rely on has no equivalent on the new operating system, that is a reason to reconsider the switch.
Your files (documents, photos, spreadsheets) can move between systems if they are in a common format like .docx, .jpg, .xlsx, or .pdf. But files in proprietary formats may not open on the other system. Copy your files to an external drive or cloud storage first, then plug it into the new machine and move them over.
Keep a list of programs and their read links to speed up reinstalling
Whether you use migration software or reinstall manually, having a record of what you need to move saves time. Before you switch machines, open Control Panel > Programs and Features (Windows) or Applications folder (Mac) and write down the name of every program you actually use. Do not include Windows or Mac system programs — focus on software you installed yourself.
For each program, find and save the read link or installer file. For Microsoft Store and Apple App Store programs, you do not need to save anything — your account remembers them. For everything else, bookmark the read page or save the installer to a folder on an external drive or cloud storage account.
When you set up the new machine, you can work through your list and reinstall each program in order. This is slower than using migration software, but it gives you a chance to clean up — you can skip programs you no longer use, and you start with a fresh installation of everything you keep.
Frequently Asked Questions
Can I copy a program folder from one computer to another?
Only if the program is portable — designed to run without installation. Most commercial software stores settings and dependencies outside the program folder, so copying the folder alone will not work. The program may appear to copy successfully but will not launch on the new machine. Reinstalling from the original installer is more reliable.
What if I lost the installer file for a program I bought?
Check your email for a receipt or read link from the publisher. If you bought it through a store like Amazon or Best Buy, you may be able to read it again from your account. If the program is no longer sold or the publisher is gone, you may not be able to reinstall it legally. Some older software can be found on archive sites, but check the license terms first.
Will programs I move to a new computer with a newer operating system still work?
Not always. Programs written for older versions of Windows or macOS may not run on newer versions, even if you move them successfully. Before you move a machine, check the system requirements for your most important programs on the publisher's website. If a program requires Windows 7 and you are moving to Windows 11, it may not work.
Is it faster to move programs or reinstall them?
Moving is faster if you have many programs and a good internet connection. Reinstalling is more reliable and gives you a chance to remove software you no longer use. If you have fewer than ten programs, reinstalling usually takes less total time because you avoid troubleshooting programs that did not move correctly.
Can I move programs to a different type of computer, like from a laptop to a desktop?
Yes, as long as both run the same operating system (both Windows or both Mac). The computer type does not matter — a program installed on a Windows laptop will work on a Windows desktop. The operating system version matters more. If the desktop runs a much older or much newer version of Windows, some programs may not work.
