Project: Which Services can be Disabled WITHOUT Drastic Impact.

@Paul Black

I've used Black Viper's Services settings since the XP days. The SAFE column is just that... Services you set w/o problems.
The "Tweaked" column is a bit more risky.

Scroll down a ways and you'll see the columns.

At the top left (of the column headings) change it to SHOW: ALL ...in the drop down box.

Hello Matthew,

Code:

C:\Windows\system32>SC start "WaaSMedicSvc"

SERVICE_NAME: WaaSMedicSvc
        TYPE               : 30  WIN32
        STATE              : 2  START_PENDING
                                (NOT_STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN)
        WIN32_EXIT_CODE    : 0  (0x0)
        SERVICE_EXIT_CODE  : 0  (0x0)
        CHECKPOINT         : 0x0
        WAIT_HINT          : 0x7d0
        PID                : 5616
        FLAGS              :

C:\Windows\system32>SC stop "WaaSMedicSvc"
[SC] ControlService FAILED 1062:

See the screenshot below.

Code:

Microsoft Windows [Version 10.0.19042.746]
(c) 2020 Microsoft Corporation. All rights reserved.

C:\Windows\system32>Net start "WaaSMedicSvc"
The Windows Update Medic Service service is starting.
The Windows Update Medic Service service could not be started.

A system error has occurred.

System error 5 has occurred.

Access is denied.

So are you saying that the Service is Disabled, but it does NOT show that in the Registry because it shows the Value 3 instead of the Value 4?

Black Viper's info seems only to 2018 and not maintained thereafter:

Bear in mind changes to services are few and occasional.

Thank you BOTH. When investigating this on the MANY sites that I looked at, I came across Black Viper quite early on, and there were differing opinions on it. I have just downloaded the file and will scrutinize this further as you have BOTH recommended it as a valid option to consider.

Ghot,

Are you using ALL the items on the SAFE List on your current Win 10 please?

Yes, I am. I also use some on the tweaked list (because of things like the lack of a printer, for example).

I did come across a few, that I wasn't sure if I should change. So I just left them for a "second" run through the Services after I made a fresh backup with the ones I already changed.

Lastly, because of different hardware, not everyone has the same Services installed. So don't be surprised if you see a few differences in the Services list.

The script disables the service without changing the value in Registry.
The script disables the service by locking "WaaSMedic.exe" and "WaasMedicSvc.dll".
Registry does not know that the two system files have been locked.
The Registry value does not reflect the fact that they have been locked.
Actually, I don't know whether the service can be disabled simply by changing the value.

Thank you.

I think I will look further into this tomorrow. I will want to Disable them in the Registry in case I ever decided I did NOT want to use the WUMT anymore. This will result in me being covered BOTH ways.

I think there could be a problem with Disabling the WaasMedicSvc.dll because of Permissions in the %WinDir%\System32 Folder!

Bear in mind the safe thing to do is to leave services well alone. Services can be dependent on one another or interact in unexpected ways. Put another way, the possible benefit (a little RAM perhaps?) of disabling a service must be carefully weighed against the possible risk of future unexpected behaviour. Put yet another way- you need to know exactly what you're doing and why.
