How to fix Windows update stuck at 30 percent

Does your computer shows up “Windows Update 30% complete” while the system boots up and the Windows Update doesn’t complete the entire process? Actually, Windows does install the update up to 30% during the shut down process and the rest of the update gets installed during the reboot cycle. But, in some certain situations, the Windows Update process can be stuck at 30 percent. But, following these solutions, you can fix this Windows Update halted at the 30 percent mark.

Step 2 – The next time, you see the “Command Prompt” in the search results, right-click that and use the “Run as administrator“.

net stop bits
net stop msiserver

After this, minimize the CMD terminal.

Step 4 – Go to the File Explorer, after this.

When all these services are started, close the terminal.
