Unused WSL 2 memory gets back to Windows 10

Windows Subsystem for Linux Virtual Machine memory is now directed back to your computer when it’s no longer in use in the Linux WM. Previously, as WSL required more memory, your computer directed more memory to Linux. This resulted in low memory issues on Windows 10 as Linux memory usage would not shrink when it was no longer needed.

This major problem has now been solved and you should no longer experience low memory errors due to Linux WM usage.

Memory usage issues are very common on Windows 10 and we’ve written extensively on how to fix them. Here are three useful guides to help you out just in case:

Speaking of batch renaming your files, if you don’t know how you can quickly and efficiently batch rename your Windows 10 files, this guide will come in handy.

Microsoft removes Your Phone App dependency on Bluetooth

Microsoft partnered with Samsung to remove the peripheral role dependency for the Phone screen. This means that Your Phone App is no longer dependant on Bluetooth Low Energy connectivity.

This feature is supported on the following Samsung models: Samsung Galaxy Note 10, Samsung Galaxy Fold, S10, S10+, and S10e smartphones, as well as Samsung Galaxy A30s, A50s, and A90 devices.

To use this new Link to Windows feature, you need to install the latest Samsung updates.  As Microsoft explains:

With the new experience rolling out, we’ll be removing the Bluetooth connectivity option, effective immediately. If you were previously enjoying Phone screen over Bluetooth and you have a phone model that doesn’t yet support Link to Windows, the Phone screen node will disappear automatically within the Your Phone app. We recommend that you unpair your devices by going to the Bluetooth settings on both your PC and your Android phone, so that you don’t have a connection that is no longer in use.
