Solved Device Manager and Administrative Tools do not open

[four321zero]

So this one gave you an error?
Name : devmgmt.msc
Directory : C:\Windows\System32
Length : 145640

If yes, then what was the error?

It gives me the same message in a new window as the snapshots i attached in my original post. Snapshot 2 and 3

"navigation to the webpage was cancelled"
and the MMC error when i click on refresh.

First, let's try replacing the file.

Now you will find this easier to do by booting from a System Repair Disc and then replacing the file. This is due to permission problems. Win 7 balks when you overwrite, rename a file in systems32.

​

CREATE A SYSTEM REPAIR DISC

START | type System Repair | Enter key | Create Disc button

I'm getting ready to crash myself so will be at least 12 hours before I'm available again.

After doing further research, I have two recommendations:
1. Uninstall whatever anti-virus/anti-anything/firewall that you are using.
2. Install Microsoft Security Essentials, MSE, link in my signature.
3. After that then click on the WDO link in my signature. Put WDO on a usb stick and run WDO.
Windows Defender Offline is NOT Windows Defender.
Once again Microsoft chose a horrible name.

here is the procedure I use with WDO.

HOW TO USE WINDOWS DEFENDER OFFLINE ON A USB STICK
Windows Defender Offline
· is a free standalone, bootable malware and virus remover from Microsoft.
· performs an offline scan of an infected PC to remove viruses, rootkits and other advanced malware.

Download Windows Defender Offline (about 764 kB)

You will have the choice of downloading the 32bit version (x86) or the 64 bit version (x64).
The link will help you determine whether you are running a 32 bit version or 64 bit version of Windows

NOTE!! You can download and prepare a 32 bit version using a 64 bit version of Windows
NOTE!! You can download and prepare a 64 bit version using a 32bit version of Windows.

You run the 32 bit version on a 32 bit version of Windows.
You run the 64 bit version on a 64 bit version of Windows.

The 32 bit download file name is: mssstool32.exe
The 64 bit download file name is: mssstool64.exe

For the curious, this program was originally name Microsoft Standalone System Sweeper.


INSTALLATION:
You will need an Internet Connection.
Insert 512 mB (Microsoft’s 256 mB is no longer accurate) or larger USB stick into a usb port.
Run the downloaded program--mssstool64.exe or mssstool32.exe
NEXT button
Choose the option On a USB flash drive that is not password protected
NEXT button
NEXT button
.
The install program will format the usb stick using the NTFS format.
The install program will download about 210 mB.
The install program will name the USB stick WDO_Media32 or WDO_Media64
The WDO_Media32 usb stick will have used space of 255 mB (268,140,544 bytes)
The WDO_Media64 usb stick will have used space of 282 mB (296,165,376 bytes)
You can expect the number of mB to increase as more malware appears.

UPDATE Windows Defender Offline USB stick:
· reinsert the usb stick
· run the installation program, mssstool64.exe or mssstool32.exe, again.
· the update will download about 66 mB (mssstool32.exe) and 68 mB (mssstool64.exe).

Since the malware database is sometimes updated several times in a day, always update before running.

PERFORM AN OFFLINE SCAN
Bootup your computer from the USB stick
Windows Defender Offline will automatically perform a quick scan.
After the quick scan finishes, Choose Full Scan
Select all of your drives

The initial, full scan can easily take several hours, but
Remember, your computer is being very thoroughly checked for all types of malware.


RESULTS OF THE SCAN
The results will be in 4 log files in:
\Windows\Microsoft Antimalware\Support

Hi again,

sorry for the late reply.
Ok I think i get the gist here, basically am supposed to get rid of any malware before repairing the damage done by it.

I was reading about WDO earlier this morning, apparently it can takes upto 6 or 8 hours for a full scan. Honestly, i need my PC quite frequently (after every few hours) for my work. So i might have to push it until next month.

Is the system recovery disk method a quicker way for a temporary work around until month end? Or would it make no sense replacing the file before scanning for malware?

 

[karlsnooks]

How long depends upon many factors. Another example, on my laptop, full scan , less than 1 hour. I also have a SSD.

How long is not relevant. The result is. I'm looking forward to the logs.

 

[karlsnooks]

incidentally, as soon as quick scan is finished, you can start the full scan and go to sleep and let computer work while you sleep.

i started installing it on the USB, it started downloading 260mb of data.

My net speed is awful and has frequent disconnections. So i guess this will take a while to complete. Pray i can pause it in intervals.

Ill run the scan once its done.

hi karl...
Sorry for the delay.

I finished installing the defender in a USB.
Will scan my machine tonight and show u the logs

hi karl,

I know how to set my boot priority from my BIOS. Ive set it as Removable Device 1st. But it just doesnt boot WDO via my USB.

Ive installed it correctly. And updated as well just before booting. You can check the screen shot of how WDO has renamed by pen drive.
My PC keeps telling me, insert proper boot device and hit the enter key. My mother board is P5QPL-AM

Does your computer's bios give the opportunity of a one-time boot from USB?

On some computers, immediately after pushing the Power ON button, start tapping the F12 key and choose the option to boot from USB.

On some computers, this capability is assigned to another function key.

This is a one-time boot and doesn’t change your normal boot sequence.

If your computer doesn’t offer this capability, then you will need to boot into the bios and change the boot order there so that Boot from USB is the first choice.

You will need to consult your computer manufacturer’s documentation.
===============================================

Watch out when you boot up from the USB stick.
Come computers, put on the screen, and only for a short time, a prompt telling you to hit any key to continue booting from USB.

The manual's garbage. Tried looking it up online, no luck so far. It only contains info about connecting the hardware and the Bios Menu and using easy flash utility to update bios (which does not work for boot). I already have selected the right boot priority (removable device first and HDD as second). The manual contains no info on the boot screen or process.
Please note, the USB stick is being detected in the BIOS menu

If i select HDD as boot, i can hit alt+F2 to start the easy flash bios utility, and i can hit f8 to get the "boot normally", "last known best config" menu. Theres nothing USB or flash related.
Selecting removable device as boot, gives me that error i mentioned in the previous post.

It might be helpful if you can post a screenshot of Disk Management (maximized with columns and such adjusted to provide max info) while the USB drive is connected.

On some computers, immediately after pushing the Power ON button, start tapping the F12 key and choose the option to boot from USB.

Hi,

The options listed after tapping F12 might also be listed as USB-HDD or USB-FDD. Do you see those options from F12?

Regards,
Golden

Heres the screen shot... i guess disk management doesnt work either. So lol i guess i am just discovering newer troubles here. Says connecting to virtual disk service at the bottom. Stayed that way for over 5 mins

Golden
F12 does nothing. The only buttons that do anything in my bios are F8 DEL and ALt+F2.
None of them are relevant.

Where are the results from WDO?

No sense futzing around until your system is malware free.

i cant get the USB with WDO to boot.

USB is recognized by BIOS and BOOT priority is set to Removable Device first.
But i get the message that insert proper boot device and restart or hit enter.
