The solution to check for "Updates need PC reboot" is to do few things:
1.) Make an group policy for adding 2 Computer Configuration>Preferences>Windows Settings>Registry entries.
2.) Make 2 entries
a.) First registry entry added by Domain policy (Just copy paste into the section)
<?xml version="1.0"?>
<Registry clsid="{9CD4B2F4-923D-47f5-A062-E897DD1DAD50}" name="RebootNeeded" status="RebootNeeded" image="11" changed="2019-10-15 13:12:22" uid="{B70ACCE8-D4CA-456F-BF56-BAB6CE3DDE31}" removePolicy="1" bypassErrors="1"><Properties action="R" displayDecimal="1" default="0" hive="HKEY_LOCAL_MACHINE" key="SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update" name="RebootNeeded" type="REG_DWORD" value="00000000"/><Filters><FilterRegistry bool="AND" not="1" type="KEYEXISTS" hive="HKEY_LOCAL_MACHINE" key="SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\RebootRequired" valueName="" valueType="" valueData="" min="0.0.0.0" max="0.0.0.0" gte="1" lte="0"/></Filters></Registry>
b) Second registry entry added by Domain policy: (Just copy paste into the section)
<?xml version="1.0"?>
<Registry clsid="{9CD4B2F4-923D-47f5-A062-E897DD1DAD50}" name="RebootNeeded" status="RebootNeeded" image="11" changed="2019-10-15 13:12:30" uid="{3240771F-1ABC-4AED-BD3F-5E7781C3C5F2}" removePolicy="1" bypassErrors="1"><Properties action="R" displayDecimal="1" default="0" hive="HKEY_LOCAL_MACHINE" key="SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update" name="RebootNeeded" type="REG_DWORD" value="00000001"/><Filters><FilterRegistry bool="AND" not="0" type="KEYEXISTS" hive="HKEY_LOCAL_MACHINE" key="SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\RebootRequired" valueName="" valueType="" valueData="" min="0.0.0.0" max="0.0.0.0" gte="1" lte="0"/></Filters></Registry>
3.) In Lansweeper add an entry to registry scanning
a.) RegPath= SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update
b.) RegValue= RebootNeeded
4.) Make this report (Obviously the Domain policy will have to be in affect and applied to the Windows PC's for the "Require Reboot?" results to show up.)
