Why Does Windows 10 Update KB5073724 Fail to Install?
Windows 10 updates may fail to install due to several reasons. One common cause is insufficient disk space, as updates require sufficient storage to download, extract, and install the changes. Another reason could be corrupted system files that prevent installing updates. Additionally, issues with the Windows Update components themselves can cause Windows Update to fail to install.
- Insufficient Disk Space: Lack of free space on the system drive can cause update failures.
- Windows Update Service Issues: Problems with the Windows Update service can prevent downloads and installations.
- Third-Party Software Conflicts: Antivirus programs, VPNs, or other software may interfere with the update process.
- Corrupted Software Distribution Folder: The folder that stores temporary update files may become corrupted.
- Network Issues: Unstable or slow internet connections can disrupt download processes.
- Corrupted System Files: Damaged system files can block the update process.
- Incorrect Date and Time Settings: Incorrect system clock settings can prevent updates from installing correctly.

Reset Windows Update Components
If none of the above solutions fix the problem for you, and Windows Update still fails to install or gets stuck checking updates for hours, it might be that something went wrong with the update files themselves.

- Again, open Windows Services and restart the services you previously stopped (Windows Update and BITS).
- Restart Windows and check for updates in Settings> Update & Security.

- Press Windows + R, type ncpa.cpl, and click OK.
Right-click your active network connection (e.g., Wi-Fi or Ethernet) and select Properties. - Double-click Internet Protocol Version 4 (TCP/IPv4) in the list to open its Properties dialog.
- Here, select the radio button Use the following DNS server addresses
