Thats actually not a bug, its a feature of Windows 10.

Heres how it works.

You only have so much space in RAM to store data.

How Windows 10 Handles Memory Management

Windows 10 still uses a pagefile when it has to.

The trade off, of course, is that decompressing the compressed memory takes up more CPU cycles.

All of the compressed memory that Windows 10 creates is stored in the System process.

This is why it appears to balloon over time.

As weve discussed before, unused RAMis wasted RAM.

Unless your gear is running slowly, you shouldnt worry about programs using lots of RAM.

Its a good thing.

If this is happening to you, there are a few things you might do.

The more real RAM space you have, the less Windows 10 needs to compress it.

Ultimately, not much has really changed.
