Windows 11 updates can fail for many reasons, including corrupted update cache, low disk space, damaged system files, unstable internet, security software conflicts, or compatibility issues with your current Windows build. This guide explains how to Fix Update KB5101650/KB5100998 Not Installing Windows 11 safely. You will also learn what to do if files go missing after a failed update, rollback, or Windows reset.

Part 1. Why Update KB5101650/KB5100998 Is Not Installing on Windows 11

When Windows Update fails, the issue is not always caused by the update package itself. Your system may be unable to download, verify, unpack, or install the update because of local Windows Update errors. That is why the same update may install successfully on one PC but fail repeatedly on another.

Below are common reasons why users need to Fix Update KB5101650/KB5100998 Not Installing Windows 11:

Part 2. Before Installing KB5101650/KB5100998

Before downloading anything manually, confirm that KB5101650 or KB5100998 appears in your Windows Update page, Update history, or Microsoft’s official update sources. If you only see these KB numbers on a third-party website, do not download unknown installers.

To check your update history, go to:

Settings > Windows Update > Update history

Note: If KB5101650 or KB5100998 does not appear in Microsoft Update Catalog or official Microsoft sources, avoid random .msu or .cab files from unknown sites. Fake update packages may damage Windows or put your data at risk.

Part 3. How to Fix Update KB5101650/KB5100998 Not Installing Windows 11

Try the following methods in order. Start with simple checks, then move to deeper repairs if the update keeps failing.

Fix 1. Restart Your PC and Check Windows Update Again

A pending restart is one of the simplest reasons Windows Update fails. Restart your PC, plug in your laptop, connect to a stable network, and check for updates again.

Instructions. Open Settings > Windows Update and click Check for updates. If the update downloads again but fails during installation, continue with the next fix.

Fix 2. Free Up Disk Space

Windows updates need enough free space to download, extract, and install files. If your C drive is almost full, KB5101650/KB5100998 may fail or roll back.

To free space, open Settings > System > Storage, run Temporary files cleanup, empty Recycle Bin, move large files to an external drive, and uninstall apps you no longer use.

Fix 3. Run the Windows Update Troubleshooter

Windows 11 includes a built-in troubleshooter that can detect and repair common update problems. Microsoft also recommends using Windows Update troubleshooting steps when updates fail to install.

Step 1. Open Settings and go to System > Troubleshoot > Other troubleshooters.

Step 2. Find Windows Update and click Run.

Step 3. Restart your PC after the troubleshooter finishes, then check whether KB5101650/KB5100998 installs successfully.

Fix 4. Reset Windows Update Cache

A corrupted update cache can make Windows repeatedly download or install a broken package. Resetting the cache forces Windows to fetch fresh update files.

Open Command Prompt as administrator, then run these commands:

net stop wuauserv

net stop bits

net stop cryptsvc

Next, rename the update cache folders:

ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

ren C:\Windows\System32\catroot2 catroot2.old

Restart the services:

net start wuauserv

net start bits

net start cryptsvc

Restart your PC and check Windows Update again.

Fix 5. Repair System Files with SFC and DISM

If Windows system files or the component store are damaged, updates may fail with errors like 0x80073712 or 0x800f081f. SFC and DISM can repair many Windows file integrity problems.

Open Command Prompt as administrator and run:

sfc /scannow

After it finishes, run:

DISM /Online /Cleanup-Image /RestoreHealth

Restart your PC and try installing the update again.

Fix 6. Disable VPN, Proxy, or Antivirus Temporarily

VPNs, proxies, firewalls, or third-party antivirus tools may interrupt Windows Update downloads. Temporarily disable them and try again from a stable home network.

Do not leave protection disabled permanently. Turn security tools back on after the update finishes.

Fix 7. Install the Update from Microsoft Update Catalog

If Windows Update still fails, you can try manual installation, but only from Microsoft’s official source.

Instructions. Visit the Microsoft Update Catalog, search for KB5101650 or KB5100998, download the correct package for your Windows 11 version and system type, run the installer, and restart your PC.

If the KB number does not appear in Microsoft Update Catalog, do not download it from random third-party websites.

Fix 8. Check Your Windows 11 Version

Some updates only apply to specific Windows 11 builds. If your device is on an unsupported or mismatched version, the update may fail.

Instructions. Press Windows + R, type winver, and press Enter. Check your Windows 11 version and build number. If needed, install available feature updates first, then retry KB5101650/KB5100998.

Fix 9. Perform a Clean Boot

A clean boot starts Windows with minimal startup programs and services. This helps identify whether background software is blocking the update.

Step 1. Press Windows + R, type msconfig, and press Enter.

Step 2. Go to Services, check Hide all Microsoft services, and click Disable all.

Step 3. Open Task Manager, disable startup apps, restart your PC, and try installing the update again.

After testing, restore normal startup settings.

Fix 10. Use In-Place Repair Upgrade

If none of the methods work, an in-place repair upgrade can reinstall Windows system files while keeping personal files and apps. This can fix deeper system corruption that blocks updates.

Download the official Windows 11 installation media from Microsoft, run setup, and choose the option to keep personal files and apps. Back up important files before starting.

Part 4. What If Files Are Missing After a Failed Windows Update?

Most Windows updates do not delete personal files. However, data loss can happen if the update fails, Windows rolls back incorrectly, the user resets the PC, or files are moved during troubleshooting.

Check these locations first:

• Desktop
• Documents
• Downloads
• Pictures
• Videos
• OneDrive local folder
• C:\Windows.old
• Recycle Bin

If files are still missing, stop using the affected drive immediately. New data may overwrite deleted files and reduce the chance of recovery.
