To install Windows 11 without internet, run a prepared ISO from an existing Windows installation, or choose Keep my files followed by Local reinstall in recovery. For a fresh installation of Windows 11 Home or Pro for personal use, you can install the Windows files offline, but Microsoft requires internet to finish first-time setup. Preserve your existing account if you need to reinstall without reaching that online setup requirement.
The short version
- Existing Windows installation: Run a prepared ISO from Windows and choose Not right now when Setup asks about downloading updates.
- Local reset: Choose Keep my files and Local reinstall to reinstall from local recovery files while preserving existing accounts.
- Fresh installation: Prepared USB media installs Windows files offline, but Home and personal-use Pro still require internet during first-time setup.
- Old bypasses: Historical setup commands are not supported current consumer installation options.
| Option | What works offline | Main limitation |
|---|---|---|
| In-place ISO reinstall | Reinstalls Windows while preserving existing apps, files and settings | Requires working Windows and a matching ISO for a supported installation path |
| Local reinstall with files kept | Reinstalls Windows and preserves existing accounts | Removes apps and needs usable local recovery files |
| Clean installation from USB | Installs Windows files | Consumer first-time setup still needs internet |
| Local reset removing everything | Reinstalls from local files | Removes accounts and returns you to setup |
| Prepared recovery drive | Restores the stored Windows environment | Deletes personal files and can require internet afterward |
Choose your installation route before erasing anything
Start with an in-place reinstall when Windows still opens and you want to preserve your existing apps, files, settings and sign-in. Run Setup from your current Windows desktop for this method. The ISO architecture, edition and installation language must match the supported upgrade or repair path.
A local reset is another offline option for an existing Windows 11 PC. If you choose Keep my files, Windows preserves personal files and existing user accounts but removes applications. Choosing Remove everything removes accounts too, which can bring back the internet requirement during setup.
Back up your files before either procedure, especially before choosing a clean installation. For help deciding what survives each installation choice, follow the steps to reinstall Windows 11 and choose what to keep. Keep a working installation if your aim is to reinstall offline while retaining your account.
Prepare installation media on a connected computer
For an x64 PC, open the official Windows 11 download page on a computer with internet access. Choose Create Windows 11 Installation Media for a USB installer or Download Windows 11 Disk Image (ISO) for x64 devices for an ISO. The Installation Assistant downloads installation content, so it is not a standalone offline installer.
To create a USB installer, run the Media Creation Tool as administrator and select Accept. Select Create installation media for another PC, then select Next. Choose the installation language and edition, then select USB flash drive and an empty USB drive with at least 8 GB of space. Creating the media erases the selected drive, so copy anything you need from it first. Take the completed media to the offline PC.
An Arm-based PC needs the official Windows 11 Arm ISO instead. Choose the edition and language, then download the ISO and prepare any required manufacturer drivers before taking the media offline. The x64 Media Creation Tool and Installation Assistant do not support Arm PCs.
Reinstall from an ISO while keeping your apps
Use this route when you can sign in to Windows and have the matching official ISO ready. Mount the ISO in the existing Windows installation, then run setup.exe as administrator. Select Yes when prompted to allow Setup to run.
Choose Change how Setup downloads updates, select Not right now, then select Next. This lets you proceed without downloading Setup updates. Accept the license terms by selecting Accept.
Before installation, select Change what to keep, choose Keep personal files and apps, then select Next. Review what Setup will preserve and select Install. This preserves your existing data, applications and settings without creating a new account through clean-install setup.
Stop before selecting Install if Setup does not offer the preservation option you need. Confirm that the ISO's architecture, edition and installation language match the supported path for your PC. Booting from the USB starts a different procedure and does not provide this same in-place reinstall route.
Use local recovery to keep your existing account
For a Windows 11 PC with usable local recovery files, open Settings > System > Recovery. Under Recovery options, select Reset PC, then choose Keep my files. Select Local reinstall, review the proposed changes and continue through the reset wizard.
This option reinstalls Windows from files already on your PC, without downloading a replacement copy. Microsoft says this reset preserves existing user accounts as well as personal files, while applications are removed. Review the reset choices carefully before continuing.
When Windows cannot open normally, hold Shift while selecting Power > Restart from the sign-in screen. In Windows Recovery Environment, select Troubleshoot > Reset this PC, then pick Keep my files and Local reinstall from the reset options. You can also follow the steps to reset a laptop without its password when you cannot reach the desktop.
A local reset depends on functioning recovery components and usable local files. If that route fails and Windows still starts, use the prepared ISO reinstall instead. When neither Windows nor local recovery works, prepared installation media provides the clean-install route below, with the first-time setup requirement still attached.
Install Windows files from a prepared USB
Choose a clean installation when you intend to erase the destination installation. Back up the PC, then boot it from the prepared Windows installation media. Choose the language and keyboard settings, selecting Next after each.
Select Install Windows 11, then select I agree everything will be deleted including files, apps, and settings and select Next. If the Product key window appears, select I don't have a product key, choose the edition that matches your license and select Next. Select Accept on the license terms. In the Select location to install Windows 11 window, delete each partition on Disk 0 that isn't listed as Unallocated Space by selecting it and then Delete Partition. Deleting a partition erases everything on it, and if more than one disk is listed, don't change or delete partitions on any disk other than Disk 0. When only Disk 0 Unallocated Space is left, select it, select Next, then select Install.
The installer can copy and install Windows files without internet because those files are on the USB. Afterward, Windows opens its configuration wizard. Home and Pro for personal use still require a connection to finish that first-time setup, so arrange connectivity before erasing the PC if you need to finish setup immediately.
Restore Windows with a reset or recovery drive
If you want to erase an existing Windows installation using its local recovery files, open Settings > System > Recovery > Reset PC. Select Remove everything, then select Local reinstall. Review the affected drives and deletion settings, then complete the reset wizard. This removes existing accounts and can return you to online first-time setup.
You can also prepare a Windows Recovery Drive before a failure. Search Start for Recovery Drive and open it, then select Back up system files to the recovery drive and select Next. Choose an empty USB drive, select Next, then select Create.
To restore Windows, boot the prepared recovery USB and select Recover from a drive. Choose Just remove my files or choose Fully clean the drive, then select Recover. Recovery removes personal files and restores the stored Windows environment, but subsequent consumer setup can still require internet.
Manufacturer factory recovery can also restore Windows files offline when a suitable local image is available. Its availability depends on your device and recovery components. If local recovery is unavailable, use matching prepared installation media and plan for the connection required during consumer setup.
Finish first time setup with a supported connection
Microsoft does not provide a documented consumer toggle that completes first-time Home or personal-use Pro setup entirely offline. When you reach the network requirement, establish connectivity to continue. Ethernet, a compatible USB Ethernet adapter or supported cellular connectivity can provide that connection.
A missing network driver is a separate issue from having no internet service. Microsoft supports importing missing network drivers from USB during setup, so prepare the correct driver on another connected computer when needed. Installing a driver can restore access to available networking, but setup still needs an internet connection.
After completing supported setup with a Microsoft account, you can switch to a local account. Open Settings > Accounts > Your info, then select Sign in with a local account instead. Enter the local username, password and password hint, select Next, then select Sign out and finish and sign in with the local account.
Understand the limits of setup bypasses
The historical OOBE\BYPASSNRO trick is not a supported current consumer procedure. Microsoft announced removal of the script and other known local-account creation mechanisms in preview builds. Those announcements do not establish that every historical trick fails on every retail installer, but they do not make those tricks supported options.
Rufus documents an online-account removal option, but it is a third-party procedure without Microsoft support for bypassing consumer setup requirements. Rufus also does not establish compatibility across every current Windows image. For a supported offline reinstall, retain your existing account through an in-place reinstall or choose Keep my files with Local reinstall.
Frequently Asked Questions
Will Windows activate while the PC is offline?
Activation is separate from reinstalling Windows. After a reinstall, activation commonly occurs once the PC goes online, so finishing an offline reinstall does not mean activation has also completed.
Can you leave Windows 11 Home in S mode without internet?
No, switching out of Windows 11 Home in S mode requires an internet connection. Changing out of S mode is therefore not an offline alternative.
Why does recovery ask for a BitLocker key?
An encrypted device may request its BitLocker recovery key when you enter Windows Recovery Environment. Have that key ready before relying on recovery to perform a local reinstall.
Can you use any Windows Recovery Drive on your PC?
Use the recovery drive created for that device. It can restore the stored Windows environment even after a drive replacement, but it is not a general replacement for matching Windows installation media.
Does audit mode let you finish consumer setup offline?
No, audit mode is supported for deployment preparation and servicing. Microsoft explicitly says it does not bypass every part of first-time setup, so it is not a permanent substitute for completing consumer setup.
