We couldn't find a camera compatible with Windows Hello Face

The restore option should create a restore point before it rolls back, hence why a user can undo the restore. I’ve used system restore many times including the undo feature.

You can also image the drive using disk imaging software if you wish.

I use this:

Did you restart the PC after installing the driver?

As Lenovo’s fix resulted in the problem then it should be they who supply the correct driver or offer a solution.

As none of the suggestions have worked then unfortunately I’m out of options.

If I restore my system to a System Image Restore Point that has been taken on January 31st, it will replace all of my hard drive contents to the state they were on January 31st. In that state, it is not possible for the system restore feature to know anything about the current (March 19th) state as that was a future date on January 31, therefore it is also impossible for the system restore feature to have an undo function back to the current date. So I will have to manually take an image of the current state first if I intent to come back to it later.

I tried running that software of Dell. It said it installed something but I'm not sure what exactly. Anyway the camera driver version number shown in Device Manager did not change and Windows Hello Setup still couldn't find a compatible camera. So I restored to a (regular) restore point I had taken just before running the installer.

If you use a restore point there is usually an option to recover back to the current state by the undo restore feature.

Is there a potion to choose older restore points? If not then a feature update has removed the older updates.

Unfortunately there doesn’t seem to be a way of saving restore points, as for disk images then these should be on external drives anyway & will be updated. I use third party disk imaging software so have no experience with Windows own backup feature.

This is the only one I can find:

I was previously told to try older versions of the driver and apparently when I meant to go back to the latest version, I inadvertently selected the wrong driver because the drivers were not listed in order of version numbers.

Now I have version 10.13.19041.28:

But yes, this one had been there before, so the problem remains. I appreciate any further advice.

By the way, it seems I may have a backup image of my pc from the time before I uninstalled the device/driver with "Hello" in its name, and I could try restoring it temporarily in order to recover important files but I cannot keep it in that state for long because I will need to be able to use my pc in its current state. Before I try that, is there any advice you can give to me about what I should particularly do or which files to recover while in the older state?

I can try installing a driver from another pc manufacturer if the driver is for my camera model and installing it does not require me to install any bundleware.

As I've mentioned a couple of times, I contacted Lenovo before. Their resolution was to restore my PC to the factory state, which I absolutely cannot do. They also said that issues related to Windows Hello Face must be solved with Microsoft, that's why I'm posting in this forum.

I contacted Lenovo for the first time on February 2nd and before that I had uninstalled the "Hello" driver, so I suppose my System Image Restore Point from Jan 31st may still have it. But that's an image restore point, so it would replace all my hd contents. I can try restoring that image temporarily but after that I would have to restore the pc back to its current state. While in the older state, what files should I save to a memory stick so that I can use them when the pc is back in the current state?

Another question: Is there a way to specify how long Windows keeps (non-image) restore points? Now the oldest non-image restore point on the list seems to be only 16 days old.

Still another question: Is there a way to take the backup image of Jan 31st safe so that newer backups will not overwrite it even if the backup disk runs low on space?
