Before moving to a new Windows PC, run Windows Backup on the old one and verify the data you expect to see on the replacement. The app combines selected Windows preferences and app information with OneDrive folder backup. Before you rely on it, check the Microsoft account, confirm which folders have uploaded, and make a separate copy of files and application data kept elsewhere. The most revealing test is opening a few representative documents from their destination while the old computer is still available.
Check which account and folders you are using
Open Settings > Accounts > Windows backup, or search for Windows Backup from Start. Check that you are using the personal Microsoft account you plan to use on the new PC. If you switch between several accounts, write down which one owns the backup and which one owns the OneDrive folder you are inspecting. Similar display names can make it easy to check a cloud account that belongs to a different device or household member.
Select the folders you want OneDrive to back up and inspect the actual paths shown in File Explorer. The available choices can include common folders such as Desktop, Documents and Pictures. Downloaded installers in Downloads, a project stored on the D drive or a folder created at the root of C can require a separate copy. Open the files you care about and use their properties or address bar to find their location. That check is more dependable than assuming everything visible from a shortcut sits in a protected folder. See Microsoft’s Windows Backup instructions for the setup and restore sequence.
Check what Windows remembers about apps and settings
Review the options for remembering apps and preferences. Select the settings categories that matter for the replacement, then note any settings you know you will need to recreate. App restoration can offer familiar pins or ways to reinstall apps. Plan to install specialist software from its original source and check how that product handles licenses, presets, plug-ins and its own local data. A visible app pin on the new PC says little about the availability of a project last opened in the app.
Make a short list of programs whose configuration would take you time to rebuild. Examples include a photo editor with custom export presets, a password manager with a local vault, a mail client with local archives and a development environment with settings outside Documents. Use each program’s supported export or migration workflow. When it offers a secure vault or profile export, store the result in a suitable protected location and confirm you can read it with the intended tool. Add a note explaining where the file came from and which version made it.
Verify the files outside the old computer
Let OneDrive finish syncing and look for warnings about full storage, paused uploads or items with errors. In a browser signed into the same account, open OneDrive and navigate to the folders you expected to back up. Check a recently edited document, an older photo and a file you added specifically for the test. Its presence and contents tell you more than a folder name alone. If practical, compare a sample file’s modified date and size with the one on disk.
If files appear in a folder on the desktop but are missing online, check the local location and sync state. A similarly named folder under a different profile or drive may look identical at a glance. Move or copy files into the intended location only after you have confirmed where they are. When you hit a quota, resolve it before assuming uploads will complete. Large files or a slow upload connection can take time. Recheck the destination after any change so you know the original issue is resolved.
Keep separate copies of important work
For important files, keep another copy you can access independently of sync. OneDrive sync is convenient for having current copies on multiple PCs. A separate backup gives you another place to recover from an accidental change or deletion. If you already use our Windows 11 File History workflow, test a restore to a separate folder or open a backup copy before you retire the old PC. When using an external drive, verify that it contains the files you plan to keep and label it before putting it aside.
Pay special attention to work that spans several folders. A video project can reference footage on another drive, and a music project can rely on a sample library stored outside the project directory. A project file may open successfully while linked media is unavailable. Play a section of the timeline, preview the edited photos or build the project as appropriate. A real use case is the fastest way to find out whether the migration captured all the inputs.
Restore and verify on the new PC
During initial setup, sign in with the Microsoft account you used for the backup. If offered a restore, inspect the available backups and choose the old PC you prepared. After setup, give the destination time to sign in and sync. Open Windows Backup, OneDrive or Settings as appropriate to check the state. Review the restored app pins and reinstall the programs you need. If the old device is available, put it next to the new one and compare the applications and folders that matter to your daily work.
Open a few files directly on the new PC. If you need a folder while traveling, confirm its files are available offline before you leave, since an online placeholder might only fetch content when you open it. Try key hardware and settings such as your usual display arrangement and preferred text size. If a setting was unavailable in the restore, our Windows 11 text size guide shows where to set one common preference manually. Hold onto the old PC or a validated backup until you have used the new one for representative work.
Check shared folders and documents sent by colleagues separately. Access granted through a shared link may depend on the account you sign in with or permissions that the owner controls. If a project depends on those files, confirm that the replacement PC can open them with the account you plan to use.
Frequently asked questions
Can I use Windows Backup to recover the whole drive?
Use Windows Backup for the files, application information and preferences it supports. Restoring an entire drive with its partitions and installed state is a different recovery workflow. If you need that outcome, keep and test an appropriate system image or disk backup alongside the migration.
Why do I see an app on the new PC before it opens?
The restore can bring back app information or pins while the program still needs to be installed. Follow the offered installation route or get the installer from its publisher, then bring over application-specific data as needed.
Can I use the new PC before every file finishes syncing?
You can start with files already available, but check the state of folders needed for immediate work. Open a sample and make critical documents available offline when access without an internet connection matters.
How do I know whether my migration is complete?
Check the files and apps against your list, then carry out a normal task on the new PC. Open a project with linked files, produce an output and confirm you can find it again. That exercise verifies more than seeing familiar folder and app names.
