Impact of Windows 10 End-of-Support on the Corporate PC Disposal Market: Performance Data Analysis Report (Sept 2025 - Mar 2026) [HAKU Inc.]

HAKU Inc. (Headquarters: Bunkyo-ku, Tokyo; Representative Director: Hisao Tezuka), a provider of PC disposal, HDD physical destruction, and data erasure services, has released data on its corporate PC disposal and data destruction services in Tokyo for the seven-month period from September 2025 to March 2026.

Since its founding in 2007, the company has managed data destruction and disposal for over 10,000 corporate clients, primarily in the Tokyo area. The company analyzed market trends based on its service usage data.

Demand for corporate PC disposal and data destruction increased rapidly around the October 14, 2025, end of Windows 10 support. The number of corporate clients visited in Tokyo reached 148% (a 48% increase) compared to the same period in the previous year.

Survey Overview Current period: September 2025 to March 2026 (7 months) Previous period: September 2024 to March 2025 (7 months) Target area: Within Tokyo Target services: PC collection service (on-site) and HDD physical destruction service Aggregation unit: Number of corporations using the service at least once per month (excluding duplicates)

Monthly Trends in Corporate Clients Visited Trends in corporate clients visited (September 2025 to March 2026, compared to the same month the previous year): September 2025: 146 → 233 (160% of previous year) October 2025: 191 → 336 (176% of previous year) ★Peak November 2025: 202 → 313 (155% of previous year) December 2025: 269 → 359 (133% of previous year) January 2026: 170 → 224 (132% of previous year) February 2026: 146 → 190 (130% of previous year) March 2026: 193 → 291 (151% of previous year) Total: 1,317 → 1,946 (148% of previous year)

Key Highlights [Demand Concentrated Around the Support End Date (Sept–Nov)] During the three-month period (September–November) surrounding the end of Windows 10 support (October 2025), growth of 155–176% compared to the previous year was recorded. October saw the highest growth at 176%, clearly showing the surge in last-minute disposal and data destruction needs.

[High Levels Maintained from December to March] High levels of 130–151% compared to the previous year were maintained during the usual peak months of December and March. This suggests that the trend was not just a temporary spike, but rather that PC disposal cycles were shifted forward across many companies.

[Future Outlook] Large-scale disposal demand triggered by the end of Windows 10 support appears to have plateaued around March 2026. However, HAKU anticipates that long-term demand for disposal and data destruction will remain robust, driven by the ongoing necessity for appropriate data erasure from a perspective of information security and personal information protection, particularly for Windows 11-incompatible PCs.
