Windows 10: NEXTBOOK windows tablet camera

All good now, thanks for everything everybody

 

These tablets have 32GB of eMMC memory (very similar to SSD). You don't defragment SSD's or eMMC, and de-fragmenting hard drives was never to recover free space, it was to make files contiguous to reduce the amount of seeking the read/write head had to physically do, thus making file access faster.

SSDs (and eMMC memory) do not have read write heads, so there is no advantage to having all the files contiguous. SSDs and eMMC have trim instead of de-fragmenting. When a file gets deleted from an SSD, the space that the deleted file was in must be reset before it can be written to again. To make things faster these previously used spaces are not normally reset until they need to be because no free spaces are available for new files, but that takes time to reset the space and then write to it. The TRIM process goes through and resets all these spaces all at once, so new file writes occur approximately twice as fast because the reset function was already done. Windows by default is supposed to TRIM the SSD (or eMMC memory) once a week, but the user can also initiate a manual TRIM just like we used to be able to initiate a manual defrag.

 

lakshi,

Make sure Windows 10 on the tablet is in the Compact OS state. From an elevated "run as administrator" command prompt enter:

Compact.exe /CompactOS:always

It should already be in a compact state, but if it isn't that command will put it there.

 

This is the way I understand it. Normally there are two copies of just about every Windows 10 system file. One is in the /Windows folder (or subfolders, like System32), and one is archived in a compressed state in the WinSxS folder. Turning on the CompactOS switch removes the normal Windows system file in /Windows (or subfolder) and instead makes the system use the compressed file stored in WinSxS instead. It saves something like 5-7 GB but uses a little bit more CPU power to decompress the system files when it needs to. On 32GB eMMC drives like our tablets have Windows 10 should have installed itself in Compact OS state automatically.

Well, OK... I was close above. Here's the real answer:

and you will save 2-3GB of space on 32-bit Windows 10 if CompactOS is on.

 

Thanks a ton for the info, checked my tablet, it is already in compact OS state

 

Was actually second guessing this after my post. Thanks for clearing that up *Wink.

 

Hello NavyLCDR, I have one more problem I hope you can solve. When I try to hard reset my Windows tablet I get blue screen and error "Recovery, your pc/device needs to be repaired. A required device isn't connected or can't be accessed". Please help

 

Why do you want to do a hard reset?

But, if you really want to go down that bumpy road, we can try.

1. Please post a disk management screenshot:
Disk Management - How to Post a Screenshot of - Windows 10 Forums

2. From an elevated ("run as administrator") command prompt, please post the results of:
reagentc /info

3. Do you have a microSD Card inserted? I would recommend 32GB but can probably get by with 8GB.

 

Hello NavyLCDR, I don't have a tablet with me at the moment, will try and post results tomorrow

 

Hello NavyLCDR, I did as you said and this is what i found out with cmd:

C:\WINDOWS\system32>reagentc /info
Windows Recovery Environment (Windows RE) and system reset configuration
Information:

Windows RE status: Enabled
Windows RE location: Error! Hyperlink reference not valid.
Boot Configuration Data (BCD) identifier: 3ab38172-fbe7-11e5-9eb2-ad6470e3487e
Recovery image location:
Recovery image index: 0
Custom image location:
Custom image index: 0

REAGENTC.EXE: Operation Successful.



I have attached screenshot of disk management

 

You didn't answer why you want to hard reset the tablet?

But, if you really want to, we can try this:
In disk management or MiniTool Partition Wizard Free, assign drive letter R: to the 4.88 GB Recovery Partition.
From an elevated ("run as administrator") command prompt, run:
reagentc /setosimage /path "r:\windows images" /index 1

If that command says "Operation Successful" then you should be able to do the reset.

If that command fails, you want to look at R: and find the folder containing install.wim. Then run the reagentc /setosimage command again, but put in the folder name that contains install.wim instead of "r:\windows images".

and you do have to include the quotes "" around the path - if the path contains a space in it.

This should take you back to the factory Windows 8.1.

 

I will try this solution and report back in a couple of hours...i want to reset the tablet since im getting many errors trying to repair the camera and want to take the tablet back to factory state....

 

I did as you said and selected 'Boottore" in CMD prompt. When I restarted the tablet it went into recovery mode. Thanks

 

Hello NavyLCDR, need some help on this. I solved camera problem of 3 pieces with your method. But one piece camera refuses to get repaired on windows 10. Tried everything, uninstalling drivers then windows update, tried lenovo drivers, also your method but get error "Something went wrong...error code". So, i went back to windows 8 and camera not working also. On windows 8 get error "To get started, connect a camera". Seems like hardware to me, what do u think?
