Help (deleted entries), ASAP!

[Skyren]

Hello,

I need help ASAP. I have deleted some sub-entries of HKLM\SYSTEM\ConstrolSet001\Control\Network or HKLM\SYSTEM\CurrentControlSet\Control\Network... I am not sure exactly.

Anyways, it cause major problem of Wireless Adapter not being detected at all.
When I am trying to install the driver, there is message that device has not been detected, try to plug/replug or similar.
Even status led is inactive and Wireless Adapter is plugged. I've tried Tweaking.com tools but they didn't work, althought they fixed many issues.

What should I do?

Windows 10 Pro
TP-LINK TL-WN751ND v2

Thank you very much for any solutions!

I'd try your restore points first to before you did this.

Otherwise, open a Command Prompt (Admin) and enter netcfg -d followed by shutdown /r /t 00 to effect an immediate reboot and then see if your adapters have been restored.

EDIT - I've removed your duplicate thread.

[Skyren]

Thanks for reply!

I've got no restore point from the time registry were fine. I am about to create restore points with your tools from now.
The steps given didn't work either.

Check attachments, first is when I try to install driver manually with .inf file while rest is regedit

One more.

Those registry entries are meaningless to me.

Is that TP-Link a dongle or the name of the built in adapter ?

Is System Protection enabled as I would have thought there would be some restore points.

I've noticed people have much more values in "Network" whereas I have only few...

I've had defender/firewall/updates and all this disabled so there was no restore point.
I had really old build of Windows 10. Now it's updated to the most recent and I have only defender disabled, rest is default.

Can't be fixed by deleting Network entry completely?

I wouldn't mess with the registry any more.

I don't think it would be worth deleting the SSID from Profiles and Unmanaged Signatures which for me is the only thing I would remove.

I would try switching the machine off and switch off at the wall and remove the adapter then hold the power button in for ~30secs.

Refit the card as for first time then switch the machine back on to see if it reinstates.

I'm not sure if a sfc /scannow either done from within Windows or as an offboot would restore the registry should that not work.

I did so, the main BIOS was corrupted so it did restore from backup BIOS, but when I get to login screen, everything freezes. I gave it a second try... was in the Windows, almost everything loaded, was about to run Chrome, but it freezed.
So I unplugged adapter once again and no more freezes. This is weird...
SFC scan show no violations since I did repair with Tweaking tool yesterday.

With the card plugged in, what does Device Manager show for it ?

If it's showing, right click on it and select Properties and under the General tab will give its status and perhaps an error code.

Does clicking on Action/Scan for hardware changes do anything for you ?

I don't suppose you have run the tweaking repair program before?  If so there is a backup of your registry that you can restore.

I re-plugged while system was running and it's not detecting the card...
Before when I start normal OS it freeze, only Safe Mode worked with card plugged in, even Safe Mode with Networking was freezing.
To make it freeze again I have to power off completely from the socket.

Unfortunatelly HW changes don't detect card either...

I messed it up pretty long time ago and only backup of registry was from the CCleaner.

In Safe Mode with Networking in Win 10, wireless is disabled anyway and you have to wire up, so not sure why it's freezing in that mode.

In just Safe Mode with the card plugged in, can you go into Device Manager/View/Show hidden devices/Network adapters then right click on the wireless adapter if displayed and check to see what it says under the General tab.

I'm starting to think that the only way out of this is going to be a clean install, initially with the card removed and then install it after the clean install.

Is the card plug 'n play or did you get an install disk with it ?

There is a Network reset option in Settings/Network & Internet but the cmd netcfg -d has already done that.

[Skyren]

I will do clean install, thanks for the help though!

[Boggin]

Probably best to still create a system image onto external media and a system repair disk before proceeding.

While I believe you can still clean install Win 10 without a product key, download the free version of Speccy and under Operating System will give you the Windows assigned licence key should you need it.

When you get everything back up and running, it would be prudent to continue creating system images - and leave the registry alone

[Skyren]

I did clean install yet, problem is still here. Seems like Windows 10 is not supported.
Are there any universal drivers for Windows 10 on this exact adapter?

Would be great you to check the driver if it shows at least (Windows 10), since I have blank screen trying to hook .inf file.

[Boggin]

Resetting the BIOS and a clean install with the card removed should have cleared any bad registry entries so that the card could have been reinstalled as out of the box.

I don't know why it didn't do that.

I'm using a Win 7 driver on my Realtek wireless adapter in Win 10 so the driver for your previous version of Windows should work.

If you have any problems then use the link to Contact Tech Support.

BTW - I've been reading through your thread on tomshardware forum.

When you post the same problem on more than one forum then you should let the others know so as not to duplicate the suggestions, but I don't know why he was pointing you to an Atheros driver unless I've missed something.

In that thread you mention you are short of space on the HDD.

You can free up space by turning off Hibernate by opening a Command Prompt (Admin) and enter powercfg -off

That frees up about 6GB on my laptop.

Follow that command with defrag /c and that will defrag all volumes then enter exit to close the cmd window.
