Inefficient OneDrive Synchronization Causes Windows Explorer Slowdowns
OneDrive has become a significant performance bottleneck in daily Windows usage. Its synchronization process frequently consumes excessive disk resources, directly impacting Windows Explorer performance and making file browsing noticeably slow, regardless of the desktop PC's hardware specifications.
What is even more concerning is that this issue has persisted for years. Many users have reported the same problem, yet the recurring response is simply that the team is "aware of the issue." Despite these acknowledgments, there have been no meaningful improvements, no clear action plan, and little transparency regarding progress or future fixes.
The lack of communication and visible progress creates the impression that the user experience is not receiving the attention it deserves. For a service as important and deeply integrated into the Windows ecosystem as OneDrive, users expect greater transparency, stronger commitment, and continuous improvements to performance and reliability.
At this point, OneDrive is becoming less of a practical productivity solution and more of a source of frustration for many users. We hope Microsoft will give these concerns the priority they deserve and provide a clearer roadmap for improving both the performance and overall reliability of the service.

Sincronização ineficiente do OneDrive causa lentidão no Windows Explorer
O OneDrive tem se tornado um gargalo significativo no uso diário do Windows. A sincronização frequentemente consome recursos de disco de forma excessiva, afetando diretamente o desempenho do Windows Explorer e tornando a navegação de arquivos lenta, independentemente da configuração do computador utilizado.
O mais preocupante é que essa situação persiste há anos. Muitos usuários relatam o mesmo problema e, apesar das respostas recorrentes de que a equipe está "ciente da situação", não percebemos melhorias concretas, um plano de ação claro ou atualizações transparentes sobre o andamento das correções.
A falta de comunicação e de avanços visíveis passa a impressão de que a experiência do usuário não está recebendo a atenção necessária. Para um serviço tão importante e amplamente integrado ao ecossistema Windows, seria fundamental haver mais transparência, comprometimento e evolução contínua da plataforma.
Atualmente, o OneDrive está deixando de ser uma solução prática para muitos usuários e se tornando uma fonte constante de frustração. Esperamos que a Microsoft trate essas questões com a prioridade que merecem e forneça um posicionamento mais claro sobre os planos futuros para melhorar o desempenho e a confiabilidade do serviço.

Hi, I agree this can be painful when Explorer is waiting on sync/status overlays. A few practical things to check: pause OneDrive sync and see if Explorer becomes fast immediately, then look for a stuck file, very large folders, or folders with thousands of small files. Also try enabling Files On-Demand, excluding build/cache folders, updating OneDrive, and running onedrive.exe /reset. If it is reproducible, sending feedback with OneDrive logs is worth doing because performance issues need trace data to be fixed properly.
Thank you for the response. I think it's important to rule out a few possibilities that do not apply in my case:
- When I pause OneDrive synchronization, Windows Explorer immediately returns to normal behavior, which strongly suggests that the issue is directly related to the synchronization process.
- The problem is not related to folders containing thousands of files or to file size. The slowdown occurs when a single file is updated, regardless of whether it is small or large. In the past, only the file being synchronized would remain temporarily locked. Today, however, I notice that the entire Windows Explorer is affected, becoming slow or unresponsive for several seconds—and sometimes even minutes—until synchronization is complete.
- Approximately 80% of my OneDrive content already uses Files On-Demand on Windows 11.
- Build folders, cache folders, and development-related temporary files are kept outside of OneDrive, specifically to avoid this type of impact.
- I have already run onedrive.exe /reset multiple times throughout 2025 and 2026, with no noticeable improvement.
For these reasons, my impression is that this is not a local configuration issue, but rather a limitation, regression, or inefficiency in the synchronization engine itself and/or in the integration between OneDrive and Windows Explorer.
What I would really like to understand is whether Microsoft officially acknowledges this behavior and whether there are any plans for optimization or a fix. Similar reports have been raised by users for years, yet there appears to be no clear resolution or public update on the matter.
