How to restore reg back up when keyboard and mouse not work

April 27, 2019 at 05:48:12
Specs: Windows 10
Hello
Windows XP
I did all this:
"Open Regedit by going to START - RUN and type Regedit and hit enter. Then you should navigate to following entry in registry
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\ {4D36E965-E325-11CE-BFC1-08002BE10318}. Highlight the {4D36E965-E325-11CE-BFC1-08002BE10318} folder in the left pane, delete the following two keys in the right pane.
"UpperFilters"
"LowerFilter"
DELETE these two entries and restart your computer."
and now I have no mouse or keyboard control so I cannot access anything in Windows XP. (Keyboard works in BIOS)..
I can see the backup.reg file I made on my desktop but I have no way to get to it to restore the registry and hopefully the mouse and keyboard.

Is there anything I can do, please?
I should mention this started from a Code 41 - DVD/CDRom hardware not found although PC recognises it has the drivers - which is still not solved.

The upper/lower filter removal shouldn't have affected the keyboard & mouse. Are they USB? Did you do mess with any other settings? If you can, try using PS/2 keyboard & mouse. USB to PS/2 adapters might work, but it's generally better to use true PS/2 devices.

Side question: why are you still running XP?

Can you get into safe mode?
If so, right click on the backup.reg

Many thanks for your prompt response
The mouse is wireless, the keyboard is PS/2. I'm trying to remember if i altered anything else - i've tried a number of things to sort out the Code 41 on the drives so I'm not sure. I've tried a USB mouse and that didn't work.
Re side question - I'm still running XP because I've just been given this PC and that's what its running. Until I can sort out the DVD/CDRom drive not working (and now the keyboard and mouse) there's not much that I can do about it!

Thank you for responding so quickly.
Yes, I can get into safe mode. However, it just brings me to the start up screen to log in and of course I can't use the mouse to click on anything!

Many thanks again but I am beginning to think this is a lost cause! I just checked the BIOS and the boot order is 1. removable 2. Hard disk 3. CD Rom 4. disabled. The trouble is the removable option relates only to Floppy disks (yes, really!) There is no option to boot from a USB and the original problem was the the CD drive is not recognised.
I'm going to try anyway with a download of the software you suggested to a USB stick and see if I can get anywhere - but I'm not holding my breath.

"There is no option to boot from a USB"
You will not get that option, until you insert the media with Lazesoft on.

I just fired up an XP comp, here is the bios with an Lazesoft usb inserted.
Advanced > Hard Disk Boot Priority > Press Enter > USB-HDD0

I've changed the boot priority to Hard Disk first and USB moved to the top of the list. What I get on restart is "Disk boot failure, insert system disk and press enter". I'm just going to restart it again to see if it will change its mind.
Nope - it wants a system disk not a USB.So it looks like I'm back to the original problem that the PC recognises the drivers for the DVD/CD Rom but cannot find the hardware (gives me Code 41 error).
Aaaarghh!

That sounds like the Lazesoft install is faulty, can you try it on another comp, just to see if it boots into Lazesoft.

Code 41
Windows successfully loaded the device driver for this hardware but cannot find the hardware device. (Code 41)
A driver was loaded but Windows cannot find the device. This error occurs when Windows does not detect a non-Plug and Play device.
If the device was removed, uninstall the driver, install the device, and then click Scan for hardware changes to reinstall the driver. If the hardware was not removed, obtain a new or updated driver for the device.
If the device is a non-Plug and Play device, a newer version of the driver might be needed. To install non-Plug and Play devices, use the Add Hardware wizard. Click Performance and Maintenance on Control Panel, click System, and on the Hardware tab, click Add Hardware Wizard.
On the General Properties tab of the device, click Troubleshoot to start the Troubleshooting Wizard.

Just tried Lazesoft on this PC - it seemed to be okay. I didn't run it as this is not my PC and I don't want to accidentally alter anything.
Re Code 41 I tried all of those options as far as I could before I lost the mouse and keyboard and nothing worked.. The PC is not connected to the Internet so I could not access any newer drivers.
I have noticed that on start up (too quick to read all the details) there are two screens that amongst other things say "detect drives, none drives any found" or some similar ungrammatical comment. I can't read all of the screen as it is there and gone too quickly but it may relate to the missing DVD/CD Rom drives?

" I didn't run it as this is not my PC and I don't want to accidentally alter anything"
No need to run it, you have proved it boots.

Have you got a CD, it's worth a try, even though it wasn't obliging in Windows.
It should show in the bios.

Negotiate to C drive > Desktop & right click on backup.reg > Merge

Downloaded the Lazesoft onto the CD. Do I change the boot priority to CD first or leave it as is (USB first) and wait for the screen which asked for a system disk? Sorry for being stupid.
Apologies - just read the instructions and answered my own question.

Oh well, not so good. Inserted CD, changed the BIOS priority to CD Rom, rebooted PC - went straight to XP welcome screen and there it sits. So I take it that the CD cannot be seen by the BIOS either. I've tried with both CD Rom drives and neither want to recognise the CD.
I'll have to give it up for the moment and see what I can do tomorrow.
Many, many thanks for all your help, Johnw.
I wish you a good night's sleep and a comfy lie-in in the morning.

You should be able to see the drive in the bios, probably the first page.
As the original problem was no rom, getting the Lazesoft USB boot disk working, is our best chance.

1. If this is a brand name comp, what is the exact model?
2. If not a brand name, exact model of motherboard.
3. Have you tried all the USB ports?

As already mentioned, remove the wireless mouse and use a ps/2; and not one described as 'combo'. If mouse now works but kb doesn't you can use the on-screen kb:

Assuming it's a desktop and not a laptop you may want to open the case and see how everything is connected. Things aren't being recognized that ought to be.

It is most definitely NOT a brand name comp! It is a mish-mash of different things which is probably a large part of the problem. It was probably set up originally by someone who knew what they were doing but it has been put away for years then set up again so the guy could uninstall a lot of his software (which may have caused the original Code 41 problem?)

Motherboard: Intel (R) Pentium (R) 4 is what is says in BIOS under CPU Type and the screen briefly shows 'P5VD2 MX'. Should there be more details somewhere or do I have to open the case?

I haven't tried all the USB ports so as I don't have a ps/2 mouse I shall try all six of them. I did wonder if it might recognise one and not all of them. I have enabled the 'USB Legacy Support for USB Mouse' in BIOS but only tried one port - I shall try the rest.

I looked through the BIOS and tried changing 'Plug and Play O/S' to 'YES' - didn't seem to help.

I enabled the 'Onboard LAN Boot ROM' which I realise isn't usually done these days but this is such an old system I thought it was worth a try. When I restarted at least one of the CD Roms did 'spin up' although it didn't read from the Lazesoft CD. (I tried the CD in both drives).

No problem, all the computers I have owned, fit that category.

"P5VD2 MX"
Perfect, that's all that is needed.

"I shall try all six of them"
Good, they can fail. The rear ones usually have more power.

Okay the six USB ports had a fifty fifty reaction. Three of them did nothing at all. For the other three the icon for new hardware appeared on the bottom Start bar then disappeared with no pop up balloon. None of them allowed the mouse to operate.

I'm going to try rebooting with the USB copy of Lazesoft in each of the ports which showed a reaction and see if that gets me anywhere.

I see all your ports are USB 2.0

Prior to your rom problem, were the covers taken off & things done inside the case?

I've just put the USB stick into what I have called Port No 2 (for ease of reference) and entered BIOS to change the boot priority order. I now have a new option of 'VIA BootAgent' which I am pretty certain wasn't there before. Could this be referring to the USB stick?

I've sent an e-mail to the guy I got the PC from to ask about the covers etc. Will let you know what he says.

No, I haven't actually disconnected the drives as yet. I'm too scared of causing even more problems.

I've managed to get the USB stick to open its window on the screen but, of course, I can't press enter or use the mouse to start it.

I'm still working on the 'mouse and keyboard not working' problem for the moment as I can't access anywhere except BIOS to take any kind of action.

I'll try your suggestion later, thankyou.

Nothing to be scared of. Just temporarily unplug the power cable & data cable to the optical drive. That will eliminate it as the possible problem. Keep the PS/2 keyboard connected but if the mouse is USB or USB/wireless, unplug it. Do you know how to maneuver in Windows using just the keyboard? If not, you can always try reconnecting the USB mouse once you get into Windows.

You have plenty on your plate to try now Keyose, I'll sit back for a while & wait for your reports.
With uncabling etc, turn the power off, a lot of older comps have a separate on/off switch at the rear, next to the power cable.

Keep an eye on your Main bios window to make sure when you recable, they are picked up in the bios.

Even better when recabling, or going inside, removing items, remove the external power cable first; thus ensuring there is no connection to the mains supply - so definitely no required voltages still running about inside the computer.

AT boards were replaced in the late 90s with ATX etc... and many were (are?) unaware that though the user switches off power off at the front, there are still volts active inside, being applied to components various. Not all vintage kit had (post AT) had the second/rear mains switch either. Best to simply disconnect physically from the mains when going inside any computer; and removing the battery too if a laptop.

I spent a day sulking then decided to try again.

Still no keyboard or mouse.

In BIOS the 2 DVD/CDRom drives - TSSTcorp CDDVDW SH-S222a and Optiarc DVD RW AS-7173A are now both giving Capacity/Cylinder/Head and Sector values as 0 which I would guess is why the PC doesn't recognise them as existing.

I cannot type in the values so I take it the only way to solve that is to download new drivers. BUT as I cannot get the BIOS to boot Lazesoft from a USB or CD in a effort to repair the keyboard and mouse I think I'm flogging a dead horse here.

Many thanks to everyone who offered suggestions and so much help. Sadly, I'm obviously not up to this challenge.

I think I'll go and sulk again for a while.

There wouldn't be any c/h/s figures for optical drives. That's only for hard drives. Try one optical drive at a time. There may be a connection or jumper conflict having them on the same cable.
