How to fix “This PC can’t be upgraded to Windows 10” error on Windows 10 May 2019 upgrade

The next major feature update for Windows 10 is expected to arrive in May 2019. If you wait, it will eventually show up in Windows Updates. That said, you can get it early from the Release Preview ring. This will get you the update one month, or a few weeks early but it’s rarely worth it. The build can still have bugs which is what happened with the October 2018 update and it has happened again with the May 2019 update as well. When users try and upgrade to it, they get the “This PC can’t be upgraded to Windows 10” error (image via Microsoft).

This bug has been acknowledged by Microsoft and the fix comes from them as well.

This PC can’t be upgraded to Windows 10

This error appears when you run try to upgrade via the media creation tool that’s available on MSDN or when you try and install it via Windows updates. The cause is external drives connected to your system at the time of the upgrade. All you need to do is disconnect them from the system and then run the upgrade.

Remove everything including memory cards, USB drives, external hard drives, and even any phones that are connected to your system. After that, run the update and it should go through without any problems.


The cause behind this error has been documented by Microsoft. It has to do with drive lettering and how it’s assigned by the OS. The connected drives/devices cause the drives to be lettered so that Windows 10 ends up looking in the wrong drive for boot information. The drive letters have been reassigned so that the wrong one is labelled as the C drive or the backup/restore/boot drive.

It goes beyond saying that Microsoft needs to get its act together. This isn’t the first time a release build, one that’s meant to roll out to users on a stable build in one month, has had a major bug. Microsoft is lucky this bug is so easy to resolve but not enough people will be able to know about it before they actually start the upgrade.

There’s is a small possibility that Microsoft releases a new build that doesn’t have this problem but it’s a small one. The fix is simple as far as the target machine is concerned but the build itself will take a lot of work to fix and then it has to be tested. Fixing it now will require delaying the update (again).

How to fix Bluetooth missing after upgrade on Windows 10

Bluetooth technology, like every other type of technology, tends to evolve over time. It gets better with both hardware and software improvements and that means that eventually, the hardware will become obsolete. The technology doesn’t update often but that doesn’t mean it will never update and often it happens without you ever knowing. If you find Bluetooth missing after an upgrade on Windows 10, it is very likely because of the update. Here’s how you can fix it.


This will only get Bluetooth working on Windows 10 again. It will not force it to be compatible with services that require the latest driver or a modern chipset to work. Bluetooth will work with whatever is still compatible with it though and this may very well include most of your peripherals and Bluetooth audio devices.

This fix is only for if you’ve recently installed a Windows update, regardless if it’s one of the monthly updates or a major feature update. The monthly update, on occasion, will install new drives which is often the cause of the problem.

Fix Bluetooth missing after upgrade

First, check if you’ve installed a recent Windows update. Open the Settings app and go to the Update & Security group of settings. Select Windows Update and check your update history. If you’ve recently installed an update, try the fixes below.

Roll back driver

Open the Device Manager and look for the Bluetooth group of devices. Expand it and select your Bluetooth chip. Right-click it and select Properties from the context menu. On the Properties window, go to the Driver tab. Click the Roll back driver button and return to the older driver for your device. You may have to restart your system for the change to take effect.

Manually install Bluetooth driver

If the Roll back driver option isn’t available, you’re going to have to manually install an older Bluetooth driver. The question is which driver to install and where to get it from.

The best place to get an older version of your Bluetooth driver is to go to your chip manufacturer’s website. You can find the manufacturer name from the Device Manager (the previous screenshot shows that mine was made by Intel). Alternatively, you can check your laptop/PC manufacturer’s website where you will find older versions of drivers for various components on your system.

Download an older driver; it should be either the last one that you know worked or the very earliest version that’s available. Uninstall the current driver from Device Manager and then install the one you downloaded by choosing to manually select the driver that’s installed.

Turn on Bluetooth

Once everything is done, you will have to enable Bluetooth from inside Windows 10. You can do this from the Action Center toggle or, from the Devices group of settings in the Settings app under the Bluetooth tab.

BIOS Updates

On some systems, Bluetooth can be turned off from the BIOS. If you’ve recently updated your BIOS firmware, it’s possible that the update turned it off. Check your BIOS and see if Bluetooth has been turned off. If it has, turn it back on.

If you’re unable to turn it back on, you might have to downgrade back to the older version of your BIOS firmware.

How to view WiFi signal strength on Windows 10

If you’re home, you likely only have one WiFi network that you can connect to i.e., the one you paid for. On the off chance your neighbor has an unprotected network, you could connect to it but that’s unethical if not illegal. If you do happen to have a choice between which network to connect to, you should definitely connect to the strongest one. Here’s how you view WiFi signal strength on Windows 10.

Available networks list

If you click the WiFi icon in the system tray, you’ll see a list of the nearby networks in a pop-up. The WiFi symbol next to each network will indicate its strength. The more filled out the symbol is, the stronger it will be. Of course, this isn’t a very accurate measurement and two networks may have the same strength.

Signal strength values

If you want a more accurate way to tell which network is transmitting a stronger signal, download Nirsoft’s free app WiFiInfoView, and run it.

The app gives you information about nearby networks but since we’re interested in signal strength, only the Signal Quality column is relevant.

To make things quick and simple, the higher the number in the Signal Quality column, the stronger is the signal being transmitted from it. You should also take a look at the Average signal strength column to check if the network can consistently deliver the strength is is transmitting at the moment. It’s a good idea to allow the app to run for a few minutes so it can gather this information for some time.

All this information can be obtained regardless if you’re connected to a network or if it’s password protected or not.

Command Prompt

This method only works for the network you’re connected to. Open Command Prompt and run the following command;

netsh wlan show interfaces

Scroll to the end of the output and you will see a ‘Signal’ entry telling you how strong the signal of the network you’re connected to is. In the screenshot above, it’s 80% which more or less is the same that the WiFiInfoView app reported.


The trick again only works for the network you’re currently connected to. If you don’t like using Command Prompt, you can use PowerShell instead.

Open PowerShell and run the following command;

(netsh wlan show interfaces) -Match '^\s+Signal' -Replace '^\s+Signal\s+:\s+',''

The command will return the signal strength as a percentage. In my test, PowerShell’s value doesn’t match with Command Prompt and WiFiInfoView but it may be because the signal tends to fluctuate from time to time.

How to enable DirectPlay on Windows 10

DirectPlay is an old API library that was used by DirectX to run games. It’s so old that modern games don’t need it any more which is why, you won’t find it on your Windows 10 PC. You might have the latest version of DirectX running but DirectPlay may not necessarily be enabled. Games simply don’t need it anymore however, if you’re trying to run an older game, you will need to enable DirectPlay on Windows 10 to get it going. Fortunately, it’s pretty easy to do.

Enable DirectPlay

DirectPlay will need DirectX installed if you’re trying to run a game so go ahead and install it. Once you’ve done that, you can proceed to enable DirectPlay.

Open the Control Panel and select Programs. Click the Turn Windows features on or off option. Alternatively, open File Explorer and enter the following in the location bar. Again, click Turn Windows features on or off.

Control Panel\Programs

In the window that opens, you will see a list of features that you can enable. This is where you can enable or disable Internet Explorer if you want. In this list of items, look for Legacy Components and expand it. Under it, you’ll find DirectPlay. Select it and click OK.

The component will take some to install and you will run into one or two prompts. Once it has been installed, you will have to reboot your system for the change to take effect.

Playing games

While DirectPlay may be an essential component needed to play older games, it likely isn’t the only thing you need. Older games that were built for older operating systems, architectures, and technology relied on multiple components to run. After you enable DirectPlay on Windows 10, check what else is required to run the game you want to play.

The older the game is, the more you will need to install additional components to make it compatible. You can try looking into emulators and they may take the pain out of running an older game however, there are few emulators that can run every single legacy game there is. The games themselves are too many to account for and legacy games might span a period of ten years which will make for different requirements depending on when it was released. It’s been a while since gaming improved and quite a lot of the popular games are now old, legacy ones which is why there’s no single emulator to run them all. In fact, you might be better of running an older version of Windows in a virtual machine and installing and playing the game on it if it’s very old.

How to fix tablet mode unavailable on Windows 10

Tablet mode is a feature on Windows 10 that is, as the name describes, meant for use on tablets and touch screen PCs. That said, even if you don’t own a Windows 10 tablet or a touch screen PC, you can still turn tablet mode on. There’s a quick toggle for it in the Action Center and there’s a dedicated setting for it in the Settings app. If tablet mode is unavailable on your Windows 10 PC, there are two fairly quick fixes for it. Here’s what you can do.

Fix tablet mode unavailable

There are two things you can do to enable tablet mode when the toggle for it is disabled.

Remove external displays

Tablet mode is available for Windows 10 devices with one exception; you must not have an external display connected to your system. You can understand that this excludes all desktop systems that are running Windows 10. If you have a laptop though, regardless if it has a touch screen or not, you can use tablet mode. Remove any external displays it has and the tablet mode toggle will be active in the Action center.

Registry editor

There is one other method that you can use to force the tablet mode to turn on when it refuses to turn on. This method requires editing the Windows registry.

Use Windows Search to look for the registry editor or open the run box with the Win + R keyboard shortcut. In the run box, enter regedit and tap the Enter key.

Once the registry editor is open, navigate to the following location;


Here, look for a value called TabletMode under ImmersiveShell. If it doesn’t exist, you can create it yourself. Right-click ImmersiveShell and select New>REG_DWORD from the context menu. After you create the value, double click it and enter 1 in the value data box.

Next, you need to restart File Explorer. Open Task Manager and on the Processes tab, look for Windows Explorer. Select it and click the Restart button at the bottom. When your desktop background returns, the tablet mode should work on your system. The toggle in Action Center will be active.

Tablet mode settings

Once you’ve enabled tablet mode on Windows 10, you will likely need to tweak some of its settings. Open the Settings app and go to the Devices group of settings. Select the Tablet Mode tab and change the settings that you need to.

Tablet mode offers an alternative desktop that combines the Start menu and desktop into one. It’s a lot like the disastrous Start menu that Windows 8 came out with so if you see it, don’t panic. Just disable tablet mode and you’ll get the old desktop back.
