Bounty: 50

For the project described in Application of this question I need the best time clock precision possible, and one solution is to have a precise synchronisation of the computer’s real time clock.

  1. What is the documented precision of doing a synchro with Windows 7’s Adjust date/time > Internet time > Change settings > Update now…?

  2. More specifically, does it compensate the time server’s ping?

    Example:

    • the time server sends a packet to say it’s precisely 12:00:00.000
    • let’s say the average ping from my computer to the time server is 93ms (average ping calculated during, say, the last minute)
    • the packet from time server will reach my computer at 12:00:00.093, right?
    • then Windows should set the time to 12:00:00.093 and not 12:00:00.000, right?
  3. If not, is there a Windows software that can do such a real-time clock synchro with ping compensation or other kind of improved precision?

#StackBounty: #windows-7 #wireless-networking #troubleshooting #network-adapter #wireless-adapter Why are network adapters not working?

Bounty: 100

All devices I have tried (a laptop, all smartphones, a PlayStation) with my WiFi networks work perfectly. The only problem is my desktop PC.


Adapter No. 1

Sometimes the adapter wouldn’t even find any network (and there are lots of them as I live in a building).

When it did find the signal from my network, it was usually above 80%, so that’s not the problem. Connection was very unstable, I usually got only local access with the classic yellow admiration sign over the signal bars.

I’m on Windows 7 and my WiFi adapter was a TP-LINK TL-WN751ND (PCI).

Things I’ve tried:

  • Uninstall and reinstall drivers. This fixed the problem for a while, but after some days the exact same problem started again.

  • Disable and then enable the device. This didn’t change anything, the problem went on.

  • Reset TCP/IP settings. This didn’t work either.

Adapter No. 2

So I thought that the problem would be the network adapter. I bought a new one: TP-Link Wireless USB Adapter TL-WN823N. This one works, but 5 or 6 times a day it just doesn’t detect any network, and a reset is needed for it to start working again. The usual procedure is the following:

  1. WiFi works ok.
  2. Suddenly, it stops working. The image says “Not connected. No connections available.
    enter image description here
  3. If I click on Solve problems, Windows solves the issue straightaway. The picture says that a problem with the wireless adapter was detected, and it was corrected by restoring the adapter.
    enter image description here

Current issue

I would like to make the second adapter to work. I mean, I can get it to work every time, but it’s very annoying to do these steps all the time, and being affraid of connection being lost randomly at any moment. Is there any way to fix this permanently?

#StackBounty: #windows-7 #windows-explorer #batch #context-menu #shell-extensions Add a "Right-click on a .WAV file, Convert to MP…

Bounty: 50

I created a key in the Windows registry:

HKEY_CLASSES_ROOT*ShellConvert to MP3command

with:

"D:toolsffmpeg.exe" -i "%1" -acodec libmp3lame -vn -ar 44100 -ac 2 -ab 256k "%1.mp3"

It works, except that the filename is not exactly what I want:

Input: test.wav, Output: test.wav.mp3

whereas I’d like the output filename to be test.mp3.

I also tried with:

"D:toolsffmpeg.exe" ... "%~n1.mp3"

like in this answer, but it doesn’t work: the output is %~n1.mp3 then!

How to remove the original extension like this, and replace by .mp3?

PS: I’m looking for a solution without involving a .bat file, but only the registry. If not possible, it’s ok to use a bat file.

#StackBounty: #windows-7 #graphics-card Colors appear washed out after coming out of sleep/booting/using 3d application

Bounty: 200

I’m seeing a similar problem to the one described in this question, but my circumstances are a bit different, and the suggested solution doesn’t apply (that is, those startup entries do not exist). I was previously using an Nvidia card on my desktop computer. When that failed (hardware issue), I was using my onboard graphics (Intel HD) for a while, until I could go pick up a new card. The new card is Nvidia as well. Now, every time I boot, wake the computer from sleep, or quit a game, the colors appear washed out.

The only way to fix this is to play with the “digital vibrance” slider in the Nvidia control panel. Playing with the gamma slider does nothing, but as long as I make any change at all to the digital vibrance slider and put it back to where it was (50%), the colors will return to normal.

I’ve tried uninstalling the Intel HD Graphics software already. What else could have been left behind, in either settings or drivers/services, that could be causing this issue?

#StackBounty: #windows-7 #drivers #crash How to diagnose a faulty driver causing random restarts?

Bounty: 50

I am running Windows 7 x64. Ever since I installed the OS on my machine a couple of months ago, there has been random restarts occasionally.

  • My previous OS was Windows 8 and I did not have this issue.
  • The restart is not preceded by anything – no BSOD, no application hangs etc. It feels like somebody just hit the reset button on the motherboard

This leads me to believe that this is a crash in kernel space, i.e. either the OS itself, or one of the drivers, crashed. I suspect it might be the Nvidia display driver, or one of the ASUS motherboard drivers which rumors to be buggy according to a few forums.

What logs can I look for if it is a driver crash?

#StackBounty: #windows-7 #vmware-workstation #nvme Windows 7 SP1 with NVMe driver does not load on VMWare 14

Bounty: 50

I am testing Windows 7 Ultimate SP1 on VMWare first as right now I do not have real NVMe drive. After integrating MS hotfix KB2990941 & 3087873 the resulting Windows 7 SP1 64 ISO boots in EFI mode but does not proceed beyond Starting Windows logo screen on VMWare Workstation 14 when the disk controller is NVMe. It does not freeze as such as I see the slight steady movement of logo around itself, however it gets stuck there. Hotfixes are integrated into both Boot.wim and Install.wim

The main purpose of these fixes is to enable native NVMe driver support on Windows 7 SP1. Windows 10 ISO installs fine though with its built-in native NVMe driver. The slipstreamed Windows 7 ISO also installs fine if the virtual drive is IDE, SATA or SCSI. This step conforms that slipstreaming is fine.

Things I have tried so far but did not help

  • Integrated only KB2990941 and skipped 3087873
  • First install Windows 7 on SATA virtual drive then manually install hotfixes then add second NVME disk.
  • Found an OpenFabrics NVMe driver for Windows 7 64. Pushed it into Boot.Wim and Install.wim with DISM forceunsigned switch. Got BSOD for nvme.sys during boot.
  • As indicated on some sites, copied Boot.wim and Setup.exe from Windows 10 ISO into Windows 7 sources. This time it detects the drive and copies files but when it reboots, back to being stuck at starting windows!
  • Just for experimental purposes, tried my hands on an unofficial Windows 7 SP1 ISO available for download on third party sites. Still same result
  • Tried with both Windows 7 SP1 and Windows 7 SP1 + April 2016 roll up updates. Same result

I am now exhausted with options. It appears to me that the above hotfixes somehow do not work with VMWare Virtual NVMe controller in Windows 7 64 SP1. Can someone point me to any further troubleshooting options or any possible solution? Host OS is Windows 7 Ultimate 64 SP1 if that matters in anyway.

Thanks.

Update
Following works, it’s close but still not what I expect.

-Integrate KB2534111 in Windows 7 SP1 Ultimate 64 Bit

-Install the OS in VMWare 14 on virtual SATA HDD. Install the NVMe hotfixs.
Add NVMe virtual disk and restart VM. Now Windows 7 installs drivers and detects the virtual NVMe disk.

-However the moment I slipstream 2534111, 2990941 & 3087873 the resulting ISO stalls at Windows logo during first boot the moment it finds NVMe virtual disk.
