Remote Desktop Settings a Windows Update Can Reset NLA Remote Desktop Users and the Main Switch
Before uninstalling updates or reinstalling anything, check the handful of host settings that updates are known to reset. Five minutes with this list repairs a surprising share of update-broken Remote Desktop problems — and every check here is reversible.

Updates do not usually delete Remote Desktop. What they do is quieter: a toggle returns to its default, a security option gets enforced, a group membership gets overwritten by policy, a network profile flips from Private to Public — and the connection that worked for a year suddenly has no path in. Each setting below takes under a minute to verify, and together they form the checklist to run before any uninstall.
System Properties — Remote tab (host PC)
Allow remote connectionsMUST BE ON
Network Level AuthenticationCHECK
Remote Desktop UsersYour account listed?
Registry fDenyTSConnections0 = allowed
The three host settings worth checking after any update, before reinstalling or uninstalling anything.
1
The Main Switch — Remote Desktop Off
On the host: Settings, System, Remote Desktop — the toggle must be On. Feature updates and in-place repairs can return this to Off, and a cumulative update occasionally leaves it inconsistent with what the old panel shows
Cross-check in sysdm.cpl, Remote tab — Allow remote connections to this computer should be selected
Admins can read the truth from the registry: reg query "HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server" /v fDenyTSConnections — 0 allows connections, 1 denies them; set it with reg add "HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server" /v fDenyTSConnections /t REG_DWORD /d 0 /f only when you mean to
2
NLA — the Checkbox That Locks Out Older or Reset Clients
In the same Remote tab, Allow connections only from computers running Remote Desktop with Network Level Authentication decides whether a user must authenticate before any session screen appears
An update that enables or enforces NLA on the host instantly locks out older clients, some phone and tablet RDP apps, and thin clients that handled it differently
The correct repair is updating the client or its settings — use turning NLA off only as a short test to confirm the diagnosis, then turn it back on
3
The Remote Desktop Users Group — Where Non-Admins Live
Administrators can always connect. Everyone else must be a member of the Remote Desktop Users group on the host — memberships can be lost when accounts are recreated, PCs are rejoined to a domain, or policies are reapplied after an update
Check it in lusrmgr.msc under Groups, or from a prompt: net localgroup "Remote Desktop Users"
Add who is missing: net localgroup "Remote Desktop Users" rdpuser /add — and sign the user fully out and back in before testing
4
The Quiet Ones — Service and Firewall
Open services.msc — Remote Desktop Services (TermService) should be present and able to start; a service stuck after an update is cleared by a full restart, not by reinstalling
In Windows Defender Firewall, Allow an app through firewall, confirm Remote Desktop is allowed on the network profile you actually use — a network that flipped from Private to Public after an update silently changes which rules apply
⚠️ Honesty line: write down every setting you change and its old value. Update problems get fixed twice as fast when the second person — often future you — can see exactly what was touched, and which changes were only tests.

The complete video walks through the update-broken RDP repair on a real system, settings included.
The Remote Desktop toggle is on, but the registry value says denied. Which one is true
Treat the registry value as the effective state and fix the inconsistency: turn Remote Desktop off and back on in Settings, restart the host, then query fDenyTSConnections again. This mismatch is exactly the kind of half-applied state a interrupted update leaves behind, and the off-on cycle rewrites both stores cleanly.
Why did my network profile change to Public after the update
Windows re-evaluates the network when drivers or network components are replaced, and an unidentified or re-detected network can land on the Public profile, where Remote Desktop is blocked by default. Set the network back to Private in Settings, Network, if it is your own trusted LAN — never do this on a cafe or hotel network.
A user is in the Remote Desktop Users group but still cannot connect
Check three things in order: the account has a password (blank-password accounts cannot log on remotely), the account is not locked or expired, and the user signed out completely after being added to the group — group membership for remote logon is evaluated at sign-in, so a session that never closed keeps the old rights.
