By ｍｅｒａ今月も毎月更新されるWindowsのセキュリティ更新やバグ修正が配信されるWindows Updateの日がやってきました。今月は「緊急」が3件、「重要」が3件の合計6件となっています。早めにアップデートしておき
news.livedoor.comHere are the latest Windows Update schedule/news I can summarize for you.
- Windows Update releases typically occur on a monthly cycle, with the US timing on the second Tuesday of each month. In Japan, due to time zone differences, updates are usually published on the second Wednesday or the third Wednesday of each month. This pattern is commonly referenced by Japanese IT support pages and news outlets.[2][3][4]
- For 2026, there are indications that January updates included multiple security fixes, and overall guidance emphasizes applying updates promptly to mitigate vulnerabilities. If you’re in Zürich, syncing your device to receive updates automatically during the scheduled windows is common practice.[1][6]
- If you’re looking for a concrete monthly calendar, several regional sources publish the exact dates for each month (Japan time) and note that schedules can shift due to US/EU time differences or corporate testing windows. You can verify the specific month’s date on vendor or regional support sites.[3][4][2]

If you want, I can pull the exact dates for the next few months and present them in a clean monthly calendar, or tailor the schedule to your Windows version (e.g., Windows 10/11) and your update settings (auto vs. manual). Also, I can provide a short checklist to minimize downtime during Patch Tuesday.
