Windows time is always wrong

Windows time inaccurate is mainly caused by abnormal network time synchronization or aging of CMOS batteries. Solutions include: 1. Check the "Internet Time" setting to ensure that synchronization is enabled and use time.windows.com or ntp.aliyun.com; 2. Modify the registry key RealTimeIsUniversal to 0 to correctly identify the BIOS time; 3. Replace the motherboard CMOS battery to avoid resetting time after power outage; 4. Turn off "Auto-adjust daylight saving time" or confirm that the time zone settings are accurate. The troubleshooting order is recommended to set the software first and then the hardware problem.

Windows update stuck at 100 percent

When Windows Update is stuck at 100%, you should first confirm whether it is a system background processing rather than a real stuck.

How to fix a stuck pixel on a Windows laptop

After confirming whether it is a stickpixel, you can try software repair or lightly press the pixel. 1.
