3、同時(shí)按“Windows 徽標(biāo)鍵+R”，輸入：msconfig，按回車(Enter)

4、點(diǎn)擊“服務(wù)”>“隱藏所有 Microsoft 服務(wù)”>“全部禁用”（若您啟用了指紋識(shí)別功能，請(qǐng)不要關(guān)閉相關(guān)服務(wù)）

5、啟動(dòng)“任務(wù)管理器”，點(diǎn)擊啟動(dòng)選項(xiàng)卡，將所有啟動(dòng)項(xiàng)都禁用

6、重啟設(shè)備

方法二：

Dism /Online /Cleanup-Image /CheckHealth，按回車

Dism /Online /Cleanup-Image /ScanHealth，按回車

Dism /Online /Cleanup-Image /RestoreHealth，按回車

sfc /scannow，按回車

3、最后重啟電腦即可。

4、如果出現(xiàn)”有一些文件無法修復(fù)“的回報(bào)，重復(fù)步驟1-3幾次。
