What survives depends on whether you upgrade the same PC, install Windows from scratch, or move to a different computer. On the same PC, Windows Setup can keep your apps, personal files, and settings—but only if you choose Keep personal files and apps. A fresh installation can erase them. Moving to another PC transfers selected files and settings, not the old PC’s installed apps as working installations. Switching to a Windows 11 Arm PC also requires checking app and driver compatibility.

First, identify which kind of move you are making

Microsoft distinguishes upgrading or refreshing one device from replacing it with a different PC. The choices affect what can be retained and how it moves:

Scenario Apps Files and settings Key point
Upgrade Windows on the same PC Kept if you choose Keep personal files and apps. Kept with that choice. Starting Setup from the running Windows installation is different from booting installation media for a fresh install. Microsoft’s upgrade guidance describes the in-place route.
Fresh installation on the same PC Existing installed apps are lost. The drive is wiped, so files and settings are lost. Back up before booting from installation media. Microsoft’s installation guidance warns that this method removes existing Windows and data.
Move to a different PC Old installed apps do not transfer as working installations. Selected files and settings can be restored or transferred, subject to exclusions. Plan to reinstall desktop software and sign in or reactivate where required.
Move to a Windows 11 Arm PC Many apps may run, but compatibility depends on the app and its dependencies. Transfer behavior follows the chosen migration method. Check drivers, peripherals, games, assistive technology, and security software with their publishers. Microsoft’s Arm PC FAQ explains compatibility considerations.

Upgrading Windows on the same PC

Choose what Setup keeps

When you run Windows 11 Setup from within the existing Windows installation, the default choice is Keep personal files and apps. It retains your personal files, installed apps, and Windows settings. You can select a different outcome:

  • Keep personal files and apps: preserves files, apps, and settings.
  • Keep personal files only: preserves personal files but removes apps and Windows settings.
  • Nothing: removes personal files, apps, and settings.

Do not confuse this in-place upgrade with a fresh installation. If you boot from installation media to start a fresh install, Microsoft warns that the process completely wipes the hard drive and existing Windows installation. Back up your files before taking that route.

Check readiness before upgrading

Use Windows Update to see when Windows 11 is offered for your particular device. An offer may be delayed because of a known compatibility issue or because the device is not yet considered ready. Microsoft’s PC Health Check can help assess hardware eligibility. Windows 10 support ended on October 14, 2025; Microsoft says free Windows Update software updates, technical assistance, and security fixes ended then. A device losing Windows 10 support does not automatically make it eligible for Windows 11.

Moving files and settings to a different PC

What Windows Backup can restore

Windows Backup is linked to your Microsoft account. It can back up selected user folders to OneDrive and save settings and preferences for restoration on another PC. Microsoft also describes many installed apps and Wi-Fi information in the Backup experience, but that does not mean every application, license, local database, or app-specific setting will return as a working installation. For desktop programs, plan to download and install them again from their publisher or the Microsoft Store, then sign in or reactivate as needed. See Microsoft’s Windows Backup overview.

OneDrive is cloud storage and sync, not a complete clone of the old PC. The Microsoft Support page accessed in 2026 lists 5 GB of free OneDrive storage with a Microsoft account and 1 TB with a Microsoft 365 subscription; offers and terms can change. Check your account’s available space and make sure the folders you need are included in backup.

What direct PC-to-PC transfer includes—and excludes

Microsoft’s direct transfer experience is a separate option for moving selected files and settings. The old PC may run Windows 10 or Windows 11; the new PC must run Windows 11 version 2024 or later. Setup requires a Microsoft account on the new PC, and Microsoft says the feature currently supports most Intel- and AMD-based PCs. Its availability is not universal: Microsoft says it is not currently available in China. Consult the current direct-transfer guidance for changing eligibility details.

Both PCs need to be connected to the same Wi-Fi or LAN and plugged into power during the transfer. Review the transfer summary and confirm the destination has enough free space; Microsoft says you can adjust what transfers to fit a smaller drive. The feature copies files and settings or preferences, but excludes:

  • Applications installed on the old PC.
  • System and operating-system files, including Program Files, Program Data, and Temp.
  • Saved passwords and sign-in credentials.
  • Files on BitLocker-encrypted drives.
  • OneDrive files, which you access on the new PC by signing in to OneDrive.

Because those exclusions differ from a full system image, separately inventory local files, app licenses, saved passwords, and app-specific data before replacing the old computer. An external hard drive or portable SSD can provide a separate file backup; it will not migrate installed applications, passwords, or system files.

What changes when the destination is a Windows 11 Arm PC?

Windows 11 on Arm runs many apps. Native Arm64 versions are expected to offer the best performance; emulation can run some apps that lack a native build. Microsoft describes Prism emulation as included in Windows 11 version 24H2 for Arm PCs, while its current FAQ qualifies broader availability. Check the documentation for the specific device and Windows release rather than assuming every Arm PC has identical support.

App emulation cannot guarantee that every dependency will work. Drivers must be designed for Windows on Arm, so a device or program that depends on an incompatible driver may not work fully. Microsoft flags peripherals, some games that rely on anti-cheat drivers, some customization and assistive-technology apps, and some third-party antivirus software as areas to verify.

Before you move: a practical checklist

  1. Decide whether this is an upgrade or a replacement. An in-place upgrade and a move to another PC have different retention and transfer rules.
  2. For the same PC, select the intended Setup option. Check eligibility first; back up before a fresh installation, especially if booting from installation media.
  3. For a replacement PC, inventory what does not simply transfer. List apps, licenses, saved passwords, local databases and other local files, and device settings. Make a separate backup.
  4. Check storage and file locations. Confirm free space on the destination and identify files in OneDrive, on encrypted drives, or outside folders selected for backup.
  5. For an Arm PC, verify dependencies individually. Ask the publishers of essential apps, drivers, printers, scanners, assistive technology, games, and security software about support for the exact device and version.
