Win 32bitpro as well as Win7 64bit pro How to uninstall win 32bit ver

thanks very much, I'll check back once I finish this perhaps later this week.

by the way I have no reason to keep 32bit - I thought maybe there was a conflict between 32 and 64 - as a reason why my keyboard doesn't work

It's unlikely a conflict between the two bit versions, though we can help you remove one if you want to test it that way first: Post back a screenshot of Disk Management - Post a Screen Capture Image.

It's more likely you haven't installed the drivers for some devices or have performance Updates which apply that are not yet installed. Enable Automatically deliver drivers via Windows Update (Step 3) then run all available Important and Optional Windows Updates. After requested reboots go right back and Check for Updates again, until there are no more. Then check Device Manager if any Devices are in error, import them from the Dell Support Downloads webpage for your tag number.

If these fail and you want to reinstall follow the steps in Clean Reinstall - Factory OEM Windows 7 to get it perfect. During the actual Clean Install Windows 7 Steps 7 and 8, delete all partitions except Dell Tools, create and format new as desired for Win7 and any storage in the Unallocated Space. Before reinstall you can test running Dell Diagnostics Utility - How to Run the to see if it will run and check your hardware over. If so save that partition during reinstall, but you can delete all others since Factory Recovery will not run and System Reserved will be cut out after reinstall.

I think I must have loaded and reloaded and checked Dell for updates.....8x now...sad to say most were never upgraded or updated. Thanks anyhow. DL

re: the disc management readings I took two snips so you could read it all.

I read on through your instructions (updates) and I snipped the two images to show the actual selections are a bit different than your description. The setting was already the top selection not my personal selection (screen 2)

I gather you are asking me to go to Microsoft's site and individually click on updates?? " all available Important and Optional Windows Updates," do you mean there's a function that does this or you want me to manually do this?

All Dell 1510 drivers have been checked at the time the 64 bit upgrade was done and the keyboard dysfunction began. And since then twice more (the tedious way) using Device manager, system by system and checking for individual updates. Maybe one or two drivers had updates and even these were very old.

Happy to do this with a bit more direction. Thanks Deb
