Every article quotes the same figure — about 7 GB. That is an average, not your number. Your reserve grows with the optional features and languages installed on your system, so two identical laptops can hold different amounts. Here is how to read the exact figure from your own PC in under a minute.
Microsoft designed reserved storage to start at roughly 7 GB and then adjust. Install speech packs, handwriting features or a second display language and the reserve climbs; a plain single-language install stays near the base size. That is why arguing about the number online is pointless — your PC already knows its number, and it is printed in two places. Check both, because they answer different questions: one tells you the state, the other tells you the size.
👆 The System and reserved breakdown. The Reserved storage line is the only figure that matters for your PC — these are example values.
This is the only place Windows prints the size in plain gigabytes.
While you are on this page, notice the neighbours: the hibernation file and virtual memory sit in the same list, and on many PCs one of them is bigger than the reserve. Keep that in mind before blaming reserved storage for a full drive.
The command line answers a different question — is the reserve on or off?
DISM /Online /Get-ReservedStorageStateUse both tools together: DISM for the state, Settings for the size. If the state is disabled, the Settings page will not show a Reserved storage line at all — that absence is also an answer.
The reserve is not a fixed block. Windows sizes it to cover the optional content installed on the system, because updates must be able to service all of it.
So a work laptop with three languages can honestly show 9 or 10 GB reserved while a plain home install shows just over 7 GB. Both are normal.
Reserved storage is recalculated as the system changes. A feature update, a newly added language, or a pile of optional features can move the figure up or down, and a feature update can even switch the state back on if you had disabled it.
The habit that keeps you informed costs nothing: after any feature update, open the System & reserved page once and glance at the line. Ten seconds, and you always know what your PC is holding and why.
See the reserved storage size check done live in the video, then compare it with your own PC.
▶️ Watch Full VideoBecause the reserve follows the installed content. Different optional features and display languages produce different sizes, even on the same Windows version. Both PCs can be perfectly normal.
It usually means reserved storage is disabled on that PC, or the device was never set up with it. Confirm with DISM /Online /Get-ReservedStorageState — the output states it in plain words.
No. Windows manages and caps the reserve. It changes mainly when the installed feature and language set changes, not simply with time or use.
