Recently, my Windows 10 updates were not properly synchronised on my WSUS, so I manually synchronised my Windows 10 patches.

However, after a few hours, I discovered that nearly 70k new patches had been synced in my wsus unapproved page.

After that, when I switched to an unapproved page, it would freeze and hang, followed by an error message.

See the attached image

Error : Connection Error

An error occurred trying to connect the WSUS server. This error happens for a number of reasons

The WSUS administration console was unable to connect to the WSUS Server via the remote API.

Verify that the Update Services service, IIS and SQL are running on the server. If the problem persists, try restarting IIS, SQL, and the Update Services Service.

    Are you performing the proper WSUS maintenance including but not limited to running the Server Cleanup Wizard (SCW), declining superseded updates, running the SQL Indexing script, etc.?

    CherryZhang-MSFT,

    I tried all of the steps listed above, but the problem persisted.
    During that time, the wsus console was launched after restarting the wsus.

    But the problem started when I changed the unapproved page; it was loading and hanging, and then it reset the server node page appears

    Is there any powershell script that can reject all unapproved updates?

    My WSUS is now fully operational.

    Thank you for your input, but the above-mentioned solution did not work for me.

    I tried the following steps:

    1. Disable the WSUSPool service in IIS.
    2. Installed SSMS
    3. Connected the WSUS Database in SSMS using the server name listed below

    \.\pipe\MSSQL$MICROSOFT##SSEE\sql\query

    1. Examine the SUSDB Disk usage
    2. where Unused space reveals very little space 6.Then I downloaded WsusDBMaintenance.sql and followed the instructions from the link below.

    https://www.urtech.ca/2016/10/solved-how-to-clean-up-and-repair-wsus/

    1. The query will take 30 minutes to complete.
    2. Restarted the WSUS Application service in IIS.
    3. Start my WSUSconsole, then navigate to the unapproved page and manually decline all 70K patches from the console.

    Hi @EDP Team ,

    I have also down some research on this issue. There are many people who have encountered such problems and this problem may be caused by various reasons. Here are some solutions for your reference.

    1, I found a similar thread that many users solved the problem with this method. The following steps are for your reference:
    1)Open the IIS Manager on your PC using the search bar.

    2) Navigate to the Application Pools option in the Connections list.

    3) Select the WsusPool service in the list and click on the Recycling… option in the Actions pane.

    Note: Alternatively, you can right-click on the WsusPool service, click on the Advanced Settings… option, and set the memory limit to 0 to increase the limit to infinity value or increase the Private Memory Limit to the value you want.

    4) Untick the option Private memory usage (in KB) in the Memory Based Maximums section and click on the Next button.

    5) Ensure that the Regular time intervals option is selected in the Configure recycling events section and click on the Finish button.

    6) Right-click on the WsusPool item in the Application Pools page and click on the Start option in the drop-down menu.

    7) Restart the WSUS console using the steps explained earlier.
