KB5028997 Not Installing? Extend Windows Recovery Partition

Since June 27, 2023, Microsoft has changed the way it updates PCs that run the Windows Recovery Environment (WinRE) for Windows 11 22H2 cumulative update. This change only applies to PCs that obtain updates from Windows Update (WU) and Windows Server Update Services (WSUS).

Some computers don’t have a large enough recovery partition, which stops you from installing the update for WinRE. When you see a system event with ID 4502 in C:\Windows\System32\winevt\logs\system.evtx, it means that the recovery partition containing WinRE doesn’t have sufficient space.

Moreover, this system event displays “Windows Recovery Environment servicing failed.” With an ErrorPhase of 2. KB5028997 is a well-known update for causing the issue because it requires a larger WinRE partition.

Besides, you will experience the KB5028997 not installing issue. So, it is necessary to perform Windows Recovery partition resizing. The section below will illustrate that for you.

Two Methods to Resize the Recovery Partition

The WinRE partition is usually behind the system partition where Windows is installed. However, Windows doesn’t have a built-in feature to move partitions to expand a WinRE (recovery) partition. Fortunately, you can shrink the OS partition and delete the original recovery partition. Then create a new recovery partition.

Step 5: Shrink the OS partition by running the commands below.
