Turn TRIM back on for SSDs

RecommendedNeeds administrator rightsReboot needed

Windows tells the SSD which blocks became free after files are deleted (TRIM). It does this by default; some "optimizers" turn it off.

Expected effect

The SSD prepares free blocks in advance: writing does not slow down over time and wear is lower. Speed right now does not change.

Possible side effects

None: this is Windows' default. Deleted files on the SSD become harder to recover with data recovery tools.

What exactly changes

Registry key	Value	Type	New value
`HKLM\SYSTEM\CurrentControlSet\Control\FileSystem`	`DisableDeleteNotification`	DWord	`0`

How to undo it

Before a change NyxBoost saves the previous values; "Revert" brings them back and removes those that did not exist before.

In NyxBoost: Recovery → “Revert” next to this setting's entry.
Without the program: open the Registry Editor (regedit), go to the key from the table and put back the previous value — NyxBoost records it in its change history.

How NyxBoost checks the result

After applying, NyxBoost reads the values again and compares them with the expected ones. To see the real effect on your PC, use FPS Lab: it measures the same game before and after.
