Windows 10 reached the end of standard support on October 14, 2025, and the consumer Extended Security Updates program was always a temporary bridge rather than a long-term plan. If your PC still runs Windows 10 in late 2026, the practical choice is to back up the drive and move to Windows 11 while the machine is still healthy.

What Ended and What ESU Covered

Standard support ended on October 14, 2025. From that date, Windows 10 no longer receives feature updates, ordinary quality fixes, or driver support for new hardware. Security updates continued only through the Extended Security Updates program, which home users could join for a limited period.

ESU delivered critical and important security patches only. It did not add features, extend hardware compatibility, or repair the growing number of applications that now require Windows 11. Once the consumer enrollment window closed, the remaining protection depended on the specific program terms rather than on a normal support lifecycle.

The risk is not only malware. An unpatched browser, PDF reader, or remote desktop service is enough for an attacker to reach local files. A machine kept offline can run old software for a while, but a PC that connects to the internet, opens email, or shares a network drive should be migrated.

Decide Between ESU and Windows 11

Run the PC Health Check app before you plan anything. Windows 11 requires a 64-bit processor at 1 GHz or faster with two or more cores, 4 GB of RAM, 64 GB of storage, UEFI firmware with Secure Boot, TPM version 2.0, and a DirectX 12 graphics device. A missing TPM or an MBR disk does not always block the upgrade, but it changes the preparation work.

If the hardware qualifies, an in-place upgrade keeps applications and user folders. If it does not, you can buy a new PC and move the old drive into it as secondary storage, or keep the old machine offline for legacy software. In both cases, the data on the current disk is the part you cannot replace.

SSD capacity matters as well. An upgrade needs room for the new system image and the previous installation, so a full 128 GB drive often fails partway through. Clean up temporary files, move large media to another disk, and keep at least 20 percent of the drive free.

Back Up Before You Upgrade

Create a full system image on an external drive, not on the same disk that holds Windows. A system image captures the operating system, applications, settings, and user files, so a failed upgrade can be undone without reinstalling everything by hand.

Verify the image before you start: open the backup task, confirm the destination, and make sure the file is complete. Save BitLocker recovery keys, browser bookmarks, email account settings, and any license keys in a separate document. If the disk already shows warnings, clone it to a new SSD first and upgrade from the healthy copy.

Move to Windows 11 with Qiling Disk Master

Qiling Disk Master can image the current system and clone it to a new SSD, which is the safest order when the old drive is nearly full or already aging. Do the backup first, then use the copy for the upgrade.

Step 1. Create a Full System Backup

Choose Backup, select System Backup, and point the destination to an external disk with enough free space. Keep the default compression unless the drive is very small; compression slows the task but reduces the image size.

Step 2. Clone or Migrate the System

If you are moving to a new SSD, choose Clone and select the whole system disk as the source. Confirm the destination by capacity and model, enable alignment for the SSD, and leave the old drive connected until the first boot succeeds.

Review the clone layout before copying Windows 10 to a new SSD

Step 3. Preview and Proceed

Check the pending operations list, then click Proceed. When the task finishes, disconnect the old drive, boot from the new one, and confirm that Windows starts normally before you begin the Windows 11 upgrade.

Finish the clone and confirm the new drive boots

Frequently Asked Questions

Is Windows 10 still safe without ESU?

It is not fully safe. New vulnerabilities stop being patched, so the risk grows every month. Keep the PC offline, avoid opening unknown files, and migrate as soon as possible.

Can I upgrade to Windows 11 for free?

Yes, if the PC meets the hardware requirements and runs a supported Windows 10 release. The upgrade is delivered through Windows Update or the Installation Assistant.

Will the upgrade delete my files?

An in-place upgrade is designed to keep personal files and applications. A failed upgrade or a cleanup tool can still remove data, which is why a verified system image comes first.

Can I stay on Windows 10 after 2026?

You can keep using it, but without standard security updates. Treat it as a legacy offline machine, not as a daily computer for email, banking, or work files.
