Quick answer
The setups that go badly almost always skip the same step: verifying the backup before touching the old device. Back up first, confirm every file you care about actually made the trip to the new computer, get printers and accounts working, and only then wipe or dispose of the old machine — never the other way around, and never "I'll get to backing up eventually."
Before you touch the new computer: back up the old one
The Federal Trade Commission's consumer guidance lays out the order: Step 1, back up your information; Step 2, erase your hard drive; Step 3, dispose of your computer. Start by listing the important files and the space needed to preserve them. The options it lists are transferring files directly to the new computer, saving them to a cloud storage service, or copying them to a USB flash drive or external hard drive. If you choose cloud storage, the FTC suggests finding out what level of privacy and security each service offers and looking for one with multi-factor authentication.
A practical backup checklist:
- Documents folder (and Desktop, if you save files there — an easy one to forget)
- Photos and videos (check the phone's own backup too, if photos sync from a phone)
- Browser bookmarks and password-manager access. Prefer the manager's protected sync or migration process. Password exports may be unencrypted CSV files: do not email them or upload them to a service request, and remove temporary copies after a verified transfer.
- Email — confirm it's actually stored on a server (most webmail is) rather than only locally
- Any software license keys or account logins for programs you'll reinstall
- A rough list of installed programs, so you remember what to reinstall on the new machine
Setting up the new computer, in order
- Connect to power and Wi-Fi, and run the system updates first. A new computer may have been sitting in a box for a while; getting updates out of the way before you add data and programs means fewer interruptions and reboots mid-setup.
- Sign into the accounts that drive your backup method (cloud storage, email, browser sync) before manually copying files — many of your files may already reappear on their own.
- Transfer the rest of your backup, then open a sample of the actual files — not just check that the folder copied, but open a document, a photo, and anything else important to confirm they're intact and readable.
- Reinstall the specific programs you actually use, rather than everything that was on the old machine — a fresh start is a good moment to leave unused software behind.
- Set up your printer and any other peripherals (see below) after your core files and accounts are confirmed working, not before — troubleshooting a printer is easier without also wondering if your file transfer worked.
Adding a printer without the frustration loop
Most printer setup problems trace back to one of a few root causes, and checking them in order avoids the classic "turn it off and on again five times" loop:
- Wi-Fi band mismatch. Many home routers broadcast both a 2.4 GHz and a 5 GHz band, either under separate names or one combined name, and some printers can only use 2.4 GHz. Brother's support documentation, for example, says the machines it covers "will only connect to the 2.4 GHz wireless band," and that giving both bands the same name "may cause repeated connection loss" — its suggested fix is separate network names, with the printer on the 2.4 GHz one. Per Intel's wireless documentation, 2.4 GHz has "the longest range and wall-penetration capability of the available bands," which is handy for a printer in a far room. Check your own printer's spec sheet or manual for which bands it supports before changing router settings.
- Driver installation vs. built-in drivers. Most current operating systems can detect and install a generic printer driver automatically, but manufacturer-specific features (scanning, ink-level reporting, advanced print settings) usually need the printer maker's own driver package downloaded from their support site.
- Old print jobs stuck in the queue. A print job that failed on the old computer can sit in a queue and block new ones — clearing the print queue is a quick check before assuming the printer itself is broken.
- One device connected, another can't see it. If a laptop can print but a phone or a second computer can't, check that the second device is on the same home network as the printer — not a guest network, a neighbor's network, or a mobile hotspot. Being on a different band of the same router is not necessarily the problem; Brother notes that computers on the 5 GHz band can still communicate with its printers on the 2.4 GHz band through a dual-band router.
Retiring the old computer properly
This is the step people skip. Dragging files to the trash is not the same as erasing the computer — the FTC's guidance is to use the erase program that comes with your operating system, following the operating-system maker's supported reset or erase process. A practical order:
- Confirm your backup is complete and verified (see the checklist above) — do this before anything else.
- Sign out of accounts and deauthorize the device where relevant (cloud services, some software licenses), so the old machine doesn't keep a seat or a login tied to you.
- Use your operating system's built-in tool to erase the drive and reset to factory settings. The FTC links to the separate instructions for Windows, Chromebook, and Mac, since the steps differ.
- Pull out anything removable — SD cards, USB drives, discs in a tray — and handle those separately; resetting the computer doesn't touch storage that isn't part of it.
- Recycle or donate it. Use an appropriate electronics recycling or donation route; the FTC links to EPA resources and suggests checking with the manufacturer or an electronics store.
Check the files that matter, not just the progress bar
A transfer utility reporting success is only the start of verification. Make a short list of your irreplaceable items: current work documents, a few older files, photos from different years, bookmarks, and any locally stored data used by an application. Open a sample from each group on the new computer. Check both the contents and whether the program needed to edit them is available.
Cloud storage deserves a separate check. A file name appearing in a folder may be a placeholder that downloads when opened. That can be fine, but it is different from having an offline copy or an independent backup. Test one important document with the network disconnected if offline access matters to you. Avoid deleting files from the old machine while a synchronization service might propagate that deletion to other devices.
A useful acceptance list is concrete: open the current spreadsheet, search the photo library, send and receive a test email, join a short test call, and print a sample document. None of those checks requires sharing private contents with a technician; you can perform them while the helper watches only the relevant settings.
Reconnect accounts without handing over ownership
The owner should create or approve the main account, recovery details, and multifactor authentication. A helper can explain each screen without keeping passwords or recovery codes. For a work computer, follow the employer's enrollment and software rules rather than creating a personal account just to get past setup quickly.
List paid applications before replacing the old device. Some need a sign-out or license transfer; others must be reinstalled from the official publisher. Do not copy random program folders and assume the application has moved correctly. Keep license records somewhere the owner can access after the visit.
If account recovery is already a problem, resolve it before wiping anything. An old computer might still be your only working route to an email account or a required verification prompt. That is a reason to pause retirement, not to bypass the account's security.
Give the new computer a normal working day
Keep the old computer and verified backup available until the new setup has completed the tasks you normally do. A printer test page does not prove that two-sided printing, scanning, or a particular label format works. Try your own harmless sample files and record any exception.

FAQ
Is it safe to just drag my files to a USB drive and call it a backup? A USB flash drive is one of the options the FTC lists, but verify the copy by opening a few files from the drive afterward — a copy that quietly failed partway through is an easy way to lose files during a computer switch.
Do I need to wipe a computer before donating it, or is deleting the files enough? Use the full erase. The FTC's steps call for erasing the hard drive with your operating system's built-in program and resetting it to factory settings — deleting individual files and emptying the trash isn't the same thing.
Why won't my printer show up on my phone if it already works on my laptop? Start by confirming the phone is on the same home network as the printer (not a guest network or cellular data), then check that the printer maker's app or your phone's built-in printing option can see it. If your router combines both bands under one name and the printer is 2.4 GHz-only, the printer's own documentation may recommend separate network names.
Should I back up to the cloud or an external drive? Either works — the FTC lists both as valid options. Cloud storage keeps a copy off-site, which helps if the computer is lost or damaged, while an external drive doesn't depend on an internet connection during the transfer. Many people use both for anything irreplaceable.
