How to fix KB5052077 fails to install in Windows 10?

Microsoft released the KB5052077 update on February 25, 2025, as a preview build for Windows 10, OS Build 19045.5555. The optional, non-security update allows users and administrators to try out future fixes and improvements before their release in the March 2025 Patch Tuesday update. Some of the significant changes in KB5052077 include fixing an issue where the OpenSSH service will not start and resolving dwm.exe crashes, the Desktop Window Manager. Other changes focus on stability and performance for certain Windows elements.

While it has its benefits, KB5052077 is not installing for some users. This is normal for Windows updates, and even other updates such as KB5033375, KB5034204, and KB5034765 have also experienced issues with failed installation. Users are reporting problems ranging from not downloading the update at all to repeated error messages that halt the installation process, hence failing to install the update.

Several factors can contribute to these installation problems, including:

• Insufficient disk space. A lack of adequate storage can prevent updates from installing properly.
• Corrupted system files. Damaged or missing system files may interfere with the update process.
• Conflicting software. Third-party applications, including antivirus programs, can sometimes block updates.
• Network issues. Unstable or slow internet connections can disrupt the download or installation of updates.
• Corrupted update components. Software Distribution folder may be holding bugged caches, preventing the newest update to install correctly.

Based on these reasons, there are several solutions that should be tried when KB5052077 fails to install. For example, for those with issues related to corrupted system files, an SFC/DISM scan would be an appropriate solution. For others, where conflicting software is present, disabling security or similar apps might help.

If KB5052077 is still not installing after troubleshooting, using a powerful PC repair application FortectMac Washing Machine X9 can be a practical solution. Such software is designed to detect and fix Windows malfunctions automatically, making it especially useful when the root cause of installation failures is unclear.

Fix 1. Disable third-party antivirus software

Security programs might interrupt Windows update processes by preventing changes to the system. Running a test by temporarily turning off antivirus software will reveal if it triggers the problem.

• Open the antivirus application from the system tray or start menu.
• Locate the real-time protection or shield settings.
• Temporarily turn off the protection.
• Attempt to install the update again.

Fix 2. Run Windows update troubleshooter

Windows update troubleshooter could sometimes help you iron out issues related to Windows updates.

• Type Troubleshoot in Windows search and press Enter.
• Click Additional troubleshooters if you can't see them listed.
• Scroll down to find the Windows Update option.
• Click and select Run the troubleshooter.
• Apply the offered changes and close down the troubleshooter – see if that helps solve your problem.

Fix 3. Free up disk space

Lack of storage space can make Windows unable to install updates. Updates require temporary space to unpack and install changes, and without it, the update may fail. Deleting unwanted files and clearing space on the system drive can resolve this issue.

• Type Disk Cleanup in Windows search and press Enter.
• Pick the main drive (C: by default) and select the option Clean up system files.
• Choose the drive once more and press OK.
• From the array of files that can be cleaned, choose those taking up the most space, including Temporary Internet Files, Windows Update, and Temporary Files, among others.
• Click OK to begin the cleanup process.

Fix 4. (Re)start relevant services

If some of the services are not running, the updates might not go through, so you should either restart them or set them to run automatically.

• Type in Services in Windows search and press Enter.
• Find Windows Update.
• If it is already running, right-click and pick Restart.
• If the service is not running, double-click it, and select Automatic under the Startup type from the drop-down menu.
• Click Start, Apply, and OK.
• Repeat this process for Background Intelligent Transfer Service (BITS) and Cryptographic services.

Fix 5. Install the update manually

If the automatic update process fails, downloading and installing the update manually from the Microsoft Update Catalog can bypass potential issues with Windows Update.

• Open your web browser and navigate to the Microsoft Update Catalog.
• In the search box, enter KB5052077 and click Search.
• Locate the correct version of the update for your operating system by checking your System type (Right-click on Start and select System. Under Windows specifications, check the Version).
• Click on Download and follow the prompts to complete the process.
• Once the update is installed, reboot your system.

Fix 6. Reset Windows update components

Another reason for failed update – corrupted files in software distribution folder. You can do this by resetting Windows update components:

• Type cmd in Windows search.
• Right-click on Command Prompt and select Run as administrator.
• In the User Account Control window, click Yes.
• Stop the Windows Update Services by entering the following commands, one at a time, and pressing Enter after each:
  net stop wuauserv
  net stop cryptSvc
  net stop msiserver
  net stop bits
• Rename the SoftwareDistribution and Catroot2 folders with the following commands:
  ren C:WindowsSoftwareDistribution SoftwareDistribution.old
  ren C:WindowsSystem32catroot2 catroot2.old
• Restart the services you stopped earlier with these commands:
  net start wuauserv
  net start cryptSvc
  net start msiserver
  net start bits
• Close the Command Prompt window and try running the Windows Update again.
