Windows 10: Disk Compression - do I have it? Do I want it?

Yesterday I tried to upgrade W10, but it wouldn't load. A MS tech did a lot of things, including turning disk compression on.
My disk is only 20% full; I sure don't need compression.
So, my questions...
1) Do I want compression
2) If I don't, can I safely turn it off?
3) I can't even find it, is it even in the current version? He did it as part of a disk cleanup, but the box is not there now. (either the feature is gone, or it can't be turned off)

Thanks

:)

i want to have Hebrew on my new N96 - how do I do this?

Whoa there...

To start with, nobody from Nokia will read your message. I am not a Nokia member of staff either, I'm just a user of Nokia products like you.

Secondly, are you sure it was Nokia Israel who called you to present the N96? I doubt it because Nokia doesn't do that. I reckon it was a third party presenting themselves as a "Nokia representative" trying to sell you the N96. Furthermore, if you just told
us that Nokia hasn't yet exported the N96 to Israel, why would they be calling you trying to sell you one?

Nokia phones come with the languages used in the part of the world where they are meant to be sold. For example, the Nordic version has English, Finnish, Danish, Swedish and Norwegian. The EURO1 variant has English, French, German, Spanish, Italian, Dutch and
Portuguese. If the phone you have was intended for sale in Israel it would have had Hebrew on it to start with. The fact that it doesn't have Hebrew on it indicates that it was
not intended for sale in Israel, which is yet another indication that it is
not Nokia Israel who sold it to you.

Your gripe is with whoever sold you the phone, not with Nokia and definitely not with me.

 

Compact OS - Compress or Uncompress Windows 10 - Windows 10 Forums

1) No, but that depends, what size is your partition and free space in total, you only need about 5 GB
2) Yes, by running a command: compact /CompactOs:never
3) Run this command: compact /compactos:query

 

It says it is not compressed because Windows determined it wasn't necessary. Thank for your help.

 

It goes back to msdos days and win95 with drive space its interesting as not only does it save space it can often speed the system up loading software the speed is often controlled by how long to load it from disk with compression its a lot faster as you only load half the size decompressing in ram can be done very fast. If you have a fast ssd drive you wouldnt gain much speed but on a laptop with slow drive it can make a difference

 

Disk Compression (compact) is only necessary when you are running out space. The reason is simple. You will recover some free space but you will always incur in a noticeable performance hit.

 

Hold on - there is a BIG difference between disk compression and OS compression.

The compactos command compresses the OS but not data. This is a relatively safe option and reversible.

Compressing the disk COMPRESSES everything. It is like turning disk into a giant zip file. I strongly recommend you do not do this because if OS glitches, it might be difficult to transfer data to a new drive.

 

Which is part of "disk cleanup" and why don't I have that as an option now? So confusing.
