Hello,
Yesterday, thanks to MalwareTips community, I have solved an issue with Emsisoft Internet Security using Revo Pro: A major problem prevents the application startup
When I used Revo Pro I noticed that it cannot made a restoration point.
So I go to take a look and noticed that there is an error.

Can you help me ?

Hello @Xtwillight
Thanks, today I have no time to try all the solutions you have proposed...
I hope for tomorrow.
I'd like to know as well... :D
I will try my best to explain what I did. It's quite annoying and tiring

First of all, do this, if any of those 4 services are not running, you should set them to automatic and start. If step 8 is successful, you don't have to do the rest
  1. Click Start, click Run, type Regedit, and then click OK.
  2. Locate and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\EventSystem\{26c409cc-ae86-11d1-b616-00805fc79216}\Subscriptions
  3. On the Edit menu, click Delete, and then click Yes to confirm that you want to delete the subkey.
  4. Exit Registry Editor.
  5. Click Start, click Run, type services.msc, and then click OK.
  6. Right-click the following services one at a time. For each service, click Restart:
    • COM+ Event System
    • COM+ System Application
    • Microsoft Software Shadow Copy Provider
    • Volume Shadow Copy
  7. Click Start, click Run, type cmd, and then click OK.
  8. At the command prompt, type vssadmin list writers, and then press ENTER.
  9. If the VSS writers are now listed, close the Command Prompt window. You do not have to complete the remaining steps.

    If the VSS writers are not listed, type the following commands at the command prompt. Press ENTER after each command.
    • cd /d %windir%\system32
    • net stop vss
    • net stop swprv
    • regsvr32 ole32.dll
    • regsvr32 oleaut32.dll
    • regsvr32 /i eventcls.dll
    • regsvr32 vss_ps.dll
    • vssvc /register
    • regsvr32 /i swprv.dll
    • regsvr32 es.dll
    • regsvr32 stdprov.dll
    • regsvr32 vssui.dll
    • regsvr32 msxml.dll
    • regsvr32 msxml3.dll
    • regsvr32 msxml4.dll
    Note The last command may not run successfully.
  10. At the command prompt, type vssadmin list writers, and then press ENTER.
  11. Confirm that the VSS writers are now listed.

In the end, it should be similar to this to continue

After that, do this, however, you may not be able to change it to "volsnap". Remember how I showed you to change the permissions of "Volume". Now you have to change the owner for all values under "Volume" using the same method (for example: {0695aa21-6522-11e6-b157-806e6f6e6963}#0000000000100000). I have 13 values so I had to change the owner 13 times :(. perhaps you have less
2. Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\STORAGE\Volume
3. For each key under 'Volume', checked for the value 'Service' and make sure it is set to volsnap. If 'Service' does not exist do the following:
a. Created a new String Value called: Service
b. Set the value to: volsnap

Finally, reboot to make it work. Without reboot, you still have the problem

Finally it's working again. Thank you very much.

In my case, I have 3 usb values under STORAGE, related to Garmin Connect. I've changed them as well, although I don't think it'd be necessary.

EDIT:

Just a note... I don't know the reason but the disk C: is showed on the bottom of the list. I have 2 SSD's and 1 HDD. C: and D: are SSD and E is the HDD. Here the system restore screen shows this way now:

E: off
D: off
C: on

Any explanation for that minor point?

I dont know. maybe because of the way your sort the items. but this is not a problem
you can try to click 1 more time in Protecao

I've tried that and clicking on it doesn't change anything... it doens't sort the drives. I've tried to change the hard drives cables but received a BSOD telling inaccessible boot device. I've asked a friend to take a look at his system.

alexandrebr,
Sorry my English is not good!

Is about the sequence the Festplatten?
example: Disco 0 = Resevardo pelo Sistema/C
Disco 1=Jogos D
Disco 2= Backup E
??????

Yes. A friend of mine has checked his system and in his case the drive letter order isn't respected as well. I think it's something controlled by W10 and it ins't an issue.

Hello alexandrebr,
this Problem Is since Windows 3.0 known.
There are several possible Causes, agree as in VSS.

I will try to help you.

  • First question:
    How does it look sequence in your Bios out ?
  • Second question:
    Was the sequence the hard drives in front of the solution With the shadow copy ?
    example:
    Disco 0 = Resevardo pelo Sistema/C
    Disco 1=Jogos D
    Disco 2= Backup E

The Asrock Z77 Extreme4 UEFI shows according to the SATA Ports in which the drives are connected, just like the Disk Management (E:, D:, C: ). That's always been the sequence because W10 follows the physical connection, not the drive letter.

Towards your second question, sorry but I couldn't understand. Do you want to know if, before the system restore fix, the sequence was different? If so, I must say that W10 disk manager has always ordered the drives considering their physical ports. What calls my attention is the fact that system protection, although it follows MB connections in my system, seems to sort the drives randomly and my friend's system shows that.

Anyway, considering the W10 environment, I was hoping system protection would take the drive letters into account and show C:, D: and E: instead.
