The issue occurs as the cxf-rt-security-3.4.4.jar file is in use by a Java process.
This can be confirmed by trying to delete the cxf-rt-security-3.4.4.jar file from D:\CW\V101\web\app\WEB-INF\lib as detailed in the patches report, which would confirm that the file is in use by a Java process.
Perform below steps to resolve the issue
1) Open Task Manger
2) Right-click on the java or cwjava process
3) Select "End Task"
4) Restart the upgrade.
