OneDrive support ends on 15 August 2026 for every Windows 10 build earlier than 22H2 — Microsoft has confirmed the OneDrive desktop sync app will stop receiving updates on those devices. If your PC is on version 21H2 or older, your files will not stop syncing overnight, but you will be left without security patches, bug fixes, or new features — a risk no one should ignore. Here is everything you need to know to check your build, understand what changes, and plan your next move.
Which Windows 10 Builds Lose OneDrive Sync Support?
Microsoft’s decision targets all Windows 10 versions prior to 22H2. Specifically, Windows 10 OneDrive sync updates will cease for:
-
Windows 10 21H2 (Build 19044) and all earlier releases
-
Windows 10 21H1 (Build 19043)
-
Windows 10 20H2 (Build 19042)
-
Windows 10 2004 (Build 19041) and older
Windows 10 version 22H2 — the final and most recent release of Windows 10 — is the only build that retains OneDrive sync app support, and Microsoft has committed to continuing updates for it until October 2028, aligned with its extended support lifecycle. If you are on 22H2, you have breathing room. If you are not, the clock is ticking.
How to Check Whether OneDrive Support Ends on Your PC
Verifying your build takes under a minute. Press Windows key + R, type winver, and press Enter. A window appears showing your Windows edition and exact version number. You can also go to Settings > System > About and look for the “OS build” entry under Windows specifications. If the version shown is anything below 22H2 (19045), your device falls inside the affected range for OneDrive support ending.
What Happens When OneDrive Support Ends on 15 August 2026?
Microsoft’s cut-off is about updates, not immediate disconnection. Once OneDrive support ending takes effect for your build, the sync app will likely continue to function in a basic capacity for a period — but you will receive no further security patches, compatibility fixes, or performance improvements. Over time, this creates real risks:
-
Unpatched security vulnerabilities in the sync client itself
-
Potential incompatibility with future OneDrive cloud-side changes
-
No access to new features such as improved conflict resolution or Personal Vault updates
-
Eventual sync failures as Microsoft’s servers evolve beyond what the outdated client supports
In short, staying on a legacy build after the deadline is a ticking time bomb for data reliability and security. Treating this as a soft warning rather than a firm deadline is a mistake.
Your Migration Options Before the Deadline
You have three realistic paths forward, and the right one depends on your hardware and workflow.
Option 1: Update to Windows 10 22H2
If your device is already running Windows 10 and you do not want to change operating systems yet, simply updating to version 22H2 keeps OneDrive sync support intact until October 2028. Go to Settings > Update & Security > Windows Update and check for updates. On most supported Windows 10 devices, 22H2 is available as a free update. This is the fastest fix if your hardware does not meet Windows 11 requirements.
Option 2: Upgrade to Windows 11
Upgrading to Windows 11 is the longer-term solution Microsoft clearly prefers, and it fully resolves the OneDrive sync support question. Windows 11 ships with a deeply integrated, regularly updated OneDrive experience and continues to receive full support well into the next decade. If your hardware supports it — you will need a compatible 64-bit processor, 4 GB RAM, 64 GB storage, and TPM 2.0 — this is the cleanest path. At Buy Now Key, a genuine Microsoft Windows 11 Pro licence starts from just €17.90, making the upgrade accessible without breaking the bank. For home users, Microsoft Windows 11 Home is available from €15.60 — a permanent, one-time licence key with lifetime activation.
Option 3: Supplement with Alternative Cloud Storage
If neither update is immediately possible, consider temporarily supplementing your setup with an alternative sync tool — Google Drive, Dropbox, or similar — while you plan the migration properly. This is not a long-term solution, but it reduces the risk of losing access to cloud-synced data if OneDrive becomes unreliable on your legacy build. Back up your OneDrive folder locally before the deadline regardless of which path you choose.
Why Microsoft Is Ending OneDrive Sync Support
This move fits neatly into Microsoft’s broader platform consolidation strategy. Windows 10 itself reached end of support on 14 October 2025, meaning the operating system as a whole no longer receives security updates unless organisations pay for Extended Security Updates (ESU). Continuing to develop and test the OneDrive sync app across a fragmented landscape of pre-22H2 builds adds engineering overhead for diminishing returns — the vast majority of active Windows 10 users have already updated to 22H2, which became freely available years ago. Cutting support for older builds lets Microsoft focus engineering resources on Windows 11 and the cloud platform that drives its future revenue.
As reported by The Register, OneDrive sync app updates will continue on Windows 10 22H2 until October 2028, providing a clear and structured wind-down rather than an abrupt cut-off for all Windows 10 users at once.
Are Your Files Safe After OneDrive Support Ends?
Your files stored in the cloud on OneDrive.com are entirely unaffected by this change. The cut-off applies only to the desktop sync app — the software that keeps a local folder on your PC in sync with your cloud storage. Even if the sync app stops working correctly on your device, you can always access your files through a web browser at OneDrive.com. That said, relying on browser-only access long term is inconvenient and risky if you depend on offline access. Do not assume your files are “fine” just because the cloud copy is intact — plan the migration now while you have time.
How to Prepare a Clean Migration Plan
Follow these steps before 15 August 2026 to ensure a smooth transition:
-
Check your build (winver or Settings > About) and confirm whether you are on 22H2 or earlier.
-
Back up your OneDrive folder to an external drive or secondary storage location.
-
Attempt a Windows 10 22H2 update via Windows Update if you want to stay on Windows 10.
-
Check Windows 11 compatibility using Microsoft’s PC Health Check tool if an OS upgrade is viable.
-
Purchase a Windows 11 licence if your PC is compatible and you are ready to upgrade — our Windows licence category covers both Windows 10 and Windows 11 options at competitive prices.
-
Reinstall and relink OneDrive after the upgrade to ensure a fresh, fully supported sync setup.
Frequently Asked Questions About OneDrive Support Ending
Does OneDrive support end for all Windows 10 users?
No. Only users on Windows 10 versions earlier than 22H2 are affected. Windows 10 22H2 retains full OneDrive sync support until October 2028. If you are already on 22H2 (build 19045), you do not need to take any action specifically related to this announcement.
Will my existing OneDrive files be deleted after the deadline?
No. Files stored in your OneDrive cloud account are not affected. The change only applies to the desktop sync application on older builds. You can still access all your files through a web browser even if the sync app stops receiving updates — though for reliable day-to-day use, upgrading your OS remains the recommended course of action.
Can I keep using the OneDrive app on Windows 10 21H2 after 15 August 2026?
You may be able to use it for a period, but Microsoft will no longer patch it. Security vulnerabilities, compatibility issues, and eventual sync failures become increasingly likely the longer you stay on an unsupported build. Relying on an unpatched sync client for important data carries significant risk.
How much does it cost to upgrade to Windows 11?
At Buy Now Key, a genuine Windows 11 Pro licence is available from €17.90 and Windows 11 Home from €15.60 — both are permanent, lifetime keys with instant digital delivery. This is a one-time cost with no ongoing subscription.
What if my PC cannot run Windows 11?
If your hardware does not meet Windows 11’s minimum requirements, updating to Windows 10 22H2 is the safest short-term option, preserving OneDrive sync support until October 2028. Beyond that date, you will need either new hardware capable of running Windows 11 or to migrate your workflow to a browser-based OneDrive setup.
