Q: itunes does not recognize my phone

See the troubleshooting steps in this support document. If iTunes doesn't recognize your iPhone, iPad, or iPod - Apple Support

What computer OS are you using? What other troubleshooting have you tried, so I don't waste your time asking you to try things you have already done.

Actually, I'm trying, but you need to answer my question first.

Do you have the latest version of iTunes on the computer? The latest version is 12.5.1. Go to Help, About iTunes and see what is displayed. Also, when you removed iTunes, you should have followed the instructions in this support document, Remove and reinstall iTunes and related software components for Windows Vista, Windows 7, or Windows 8 - Apple Support

If you continue to have issues with iTunes and Windows, see this ASC User tip. Troubleshooting issues with iTunes for Windows updates

Why are you using the 32-bit version? You should be using the 64-bit. I suggest that you remove and reinstall iTunes, using the information I provided you earlier. Also, you may need to put the device into Recovery Mode to fix your problem. Had I known that earlier, I could have modified my troubleshooting accordingly. See this for Recovery Mode.  If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support

Unusual for a Windows 10 to be running 32-bit. See this additional help from the ASC User that provided the other information tip. This has to do with trying to update drivers.

If your iOS device isn't showing in iTunes try the following:

1. Open Control Panel > Device Manager
2. Plug in your device
3. Locate Universal Serial Bus Controllers > Apple Mobile Device USB Driver.
   It is also possible the device may show under Imaging Devices, Portable Devices or Other Devices or as an MTB USB Device.
4. Right-click and select Update Driver Software...
5. Click Browse my computer for driver software
6. Browse to C:\Program Files\Common Files\Apple\Mobile Device Support\Drivers or
                   C:\Program Files (x86)\Common Files\Apple\Mobile Device Support\Drivers
7. Click Let me pick from a list of device drivers on my computer
8. Click Apple Mobile Device USB Driver
9. Click Next, then Close and exit Device Manager

For step 3 above, open the device manager. Expand any of these sections that are listed.

• Universal Serial Bus Controllers
• Imaging Devices
• Portable Devices
• Other Devices

Connect the device. You should hear the telltale sound of Windows device connection and one section should gain a new entry. That should be your device. It may not be labelled correctly at this stage. If you don't hear a noise suspect a damaged cable.

Or try If iTunes doesn't recognize your iPhone, iPad, or iPod - Apple Support which is Apple's version of the advice above.

Failing that try a full tear down and rebuild of iTunes as set out in Troubleshooting issues with iTunes for Windows updates. 64-bit users could also try the alternate Download iTunes for Windows (64-bit - for older video cards) build which is sometimes a useful workaround.

Or lastly try rolling back to the last build of iTunes that worked for you. See iTunes installers for download links. If you're rolling back from 12.5.1.21 to 12.4.3.1 or 12.4.2.4, for example, then you'll also need to roll back the library database using the method described inEmpty/corrupt iTunes library after upgrade/crash. The tip includes suggestions for reintroducing any recent purchases so at worst you lose a few playcounts and/or a recently created playlist.
