Cannot Turn On Windows Defender - This App Has Been Turned Off And Is Not Monitoring Your Computer
Nov 10, 2015
I can't turn on Windows Defender. When I try to launch it, a window saying "This app has been turned off and is not monitoring your computer" pops up. I tried everything that's listed on the MS answers thread. I am unable to start the Windows Security Centre service too. It doesn't stay enabled i.e., it becomes disabled as soon as I close the Services app. I have no anti-virus installed. Been using WD since I upgraded.
I'm logged on, it's my computer, I'm the administrator, there are no AV running. However I get the system error " Windows Defender is being managed by your system administrator" controlled by group policy. All I want to do is turn it on. Local Group Policy shows nothing is configured...??
As I use a proprietary antirvirus, and on a whim, I just thought to check my Windows Defender setting, only to find to find that it was turned on*. (I could swear I turned it off, sometime in the past. I was further surprised to find that the On/Off button is disabled--so I CAN'T turn it off!
I'm further surprised to find the notice, under Settings/Windows Defender, which says "You can turn this off temporarily, but if we find that it is turned off for a while we'll turn it back on again, automatically." (One mystery solved*)
As I understand it, Windows Defender is merely Microsoft's own notion of free antivirus software--so when Windows turns Defender on again, this means I not only have two antivirus packages running (and possibly interfering with each other--involuntarily) but also that I now seem to have no choice in the matter--unless, of course, I permanently uninstall the antivirus software that I paid good money for.
Questions: How do I re-enable the Windows Defender On/Off button; and How do I DISable Windows ability to turn it on again?
My windows labtop is always turn sideways when i turn it on. I can change it when the computer is started up. How I can change it that i can get the right screen instead of the sideways screen?
I have a new Dell Computer with Windows 10. I have deleted McAfee with its on Uninstaller and also with another uninstaller. I have no other antimalware programs running. I have tried a number of ways to start Windows Defender, which is the only antimalware program listed in my Security area. I have tried to start it with Services. I get an error message as shown below. I get this error message: "The Windows Defender Service service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs." I have removed all other antimalware programs and no longer get McAfee popups.
I am having trouble with Windows Defender and Update. I am getting error 0x800705b4 for Defender and though I've searched online on how to fix the problem none of them seem to work. Also, my computer won't let me access the update & security portion of my settings. When I click on it the window closes immediately.
I've been trying unsuccessfully to use Windows Update but keep getting the error code 0x800705b4. Windows Defender is turned off, and both Windows Firewall and Norton Anti-Virus has been temporarily disabled, but it still won't work. I don't know what's wrong.
I had a lot of files so I decided to reset to factory settings. Computer at 2% turned off, so I tryed to turn it on again,but windows refused to start, it turned off after the manufacturer's logo showed, so I decided to download windows 10 installer [URL] ..... and put it into my USB. I tryed to reinstall windows through usb port, but it needs to turn on the windows that can not be launched (possibly due to incomplete reset to factory settings that might have deleted important windows files). How can I re-install windows 10 without needing to access windows?
How to stop this damn notification from popping up every five minutes? I've tried everything. I've let it scan my computer (both quick-scan and full-scan), but within five minutes the notification pops back up again. I've looked online and found that it can be down to a certain setting in CCleaner, I use CCleaner but the option that all the solutions say to untick isn't present in the latest versions.
I've had Windows for a few months now and never really had an issue until the past few days. Overall CPU performance/speed is way down. Firefox freezes then recoops every 2-3 minutes, adobe plugin constantly crashing, even to do things offline is crazy slow.
I downloaded Windows Defender probably a week or 2 ago and that is the only big change that I know of done on this computer. I used to run Malewarebytes, SuperAnti-Spyware and Advanced Windows SystemCare. But was told that Advanced Windows SystemCare was the devil and to try TFC (temp file cleaner) & MyDefrag instead. So now i'm running;
Windows Defender MalewareBytes (free) SuperAnti-Spyware(free) TFC MyDefrag
Is this combination making my computer un usable? Or something else?
I always used to set the turn off display after 2 or 3 minutes, everything was working fine with my old PC but after the new PC whenever the screen is turned off i can't turn it on again buy using the mouse or keyboard.
This problem was while using windows 8.1 and after installing windows 10 pro the problem is still there.
Tried turn off hibernate solution but with no luck.
Connection with monitor is throw HDMI cable with the internal Intel 4600 VGA Card
So I was doing a system restore on my newly upgraded Windows 10. It was stuck at 46% so I restarted it (which was a stupid thing I know). After that the laptop won't go beyond the black screen. Whenever I boot the laptop the lenovo logo appears and the black screen after and that's it. I'm really worried now.
Recently I downloaded a program but it came with a ton of malware. I booted my laptop in safe mode and ran a bunch of malware removal programs. When I tried to boot my computer back up, the screen lit up and turned grey.
So I have a bit of a problem where my screen flashes, I instantly thought it was display drivers so I uninstalled them only to worsen the problem, the computer restarted with a black screen which later turned into a desktop screen with no icons and a flashing screen (can't click anything or even load up the start menu with the windows key). I put it into safe mode but it does the same thing. Nothing works except task manager and i can't run task from it or it will exit out, system restore doesn't fix the issue either. Computer is a lenovo k450 i5-4440 8gb ram 1tb hdd with an evga gtx 760.
Desktop Icons move back to the left (default) side of the screen after customizing. this happens when the the computer is put into sleep mode and is woken up or when the monitor is turned off and turned back on. I upgraded to windows 10 Pro 64bit from windows 7 ultimate 64bit. This problem never happened with windows 7.
-Automatic Sleep mode is turned off - when I manually put computer to sleep mode and wake it up the icons are rearranged
-Automatic turn off monitor has been deactivated - when shut off my monitor but keep my computer on and then turn back on the monitor the icons have rearranged
-I have small icons setting
-Auto align icons has been deactivated
-allow themes to change icons has also been deactivated
My Computer: LG 34UM65 - 21x9 - 2560x1080p resolution AMD 9590 Asus Crosshair V Formula Z Gigabyte HD7970ghz Corsair Platinum Ram WD HDD Samsung 850Pro - Windows 10 is installed on the SSD My Drivers are all up to date. and Motherboard Bios has just been updated to 2201
My laptop, an Acer, has been freezing multiple times a day recently. Sometimes I get a blue screen eventually that tells me there's been a WHEA error, sometimes none of that. Yesterday, I kept staring at the screen for a while instead of restarting, and eventually it recovered. I could see the processor activity climb to 100%, and that interrupts claimed up to 14% of the activity. Afterwards, the network adapter (Qualcomm Atheros AR956x) was turned off, apparently because of a 'code 12' - 'insufficient available resources'.
That problem was only resolved after a restart. When I shut the computer down, I got a screen telling the computer was being 'prepared' for a long time - sometimes I also see a blue screen showing the installation of updates at start-up, even if none were waiting to be installed. The drivers for the network adapter are up to date, version 10.0.0.318 (apparently dating from May 2015). I'm quite sure this is a software issue - 'chkdsk' doesn't find any problems, nor does 'sfc /scannow'. And a friend of mine with an Apple laptop running Windows 10 (we've never exchanged USB sticks or anything) has exactly the same problem since installing Windows 10 (different network adapter however, and seems to have improved recently).
I run a plex server which periodically does highly intensive CPU Transcoding, I have found that the OS locks up if my temperatures exceed 70 C (which makes sense).This wouldn't normally be a problem but my computer takes about 15 minutes from pressing the button to settling into a stable state. To solve this problem I'd like to be able to stream SpeedFan to show me my temperatures and if possible have buttons to send commands back to the computer to turn up fans or turn down the affinity of the application (to reduce heat).
recently upgraded to win10 and that went well.. However on the last update (I think) that went bad. My pc now looses all apps when turned off. When restarted, I have to reload windows live mail and re-enter my email account. All my contacts seem to have been lost as is my email history.I use google as my web browser and I have to re-enter all my settings here also.
When turned on, my pc loads quickly but after logging on, it goes to "preparing windows" which takes some time before it is usable.
updates installed around the time of problem are;
kb3081448 kb3081449 kb3081452 kb3081444
..this is the update after which I think the problem started
i don't have any bluetooth or even wireless devices but in the action center bluetooth is always turned on! and when i click on it, Its just open Settings.
