Ah yes. Well before you alter it you have to be absolutely sure you don't want to revert back to Windows 8 after you have Upgraded to Windows 10. Basically this folder contains information that can revert you back to Windows 8. So the simple answer is just delete it.
Its a good idea to read this however, before doing so Windows.old folder - Delete in Windows 10
Hello , already deleted windows.old folder by using disk cleanup. Just need to know i have total space 28.4gb out of which 17.0gb is free....is that normal? Thanks
Yes that seems about right. The Windows 10 operating system can range from taking up 10 to 20 GB, depending on the updates you have installed and other components (e.g apps, settings add-ons etc...). So yes that's about right.
If you wanted to free up more space, see if you can delete any metro apps/programs that you don't think you'll use as these can take up quite a lot of space. Also running CCleaner may help.

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.

What is compact state and what does it do? What happens if it isn't in compact state?
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:
Windows 10: Reducing the disk footprint | Michael Niehaus Windows and Office deployment ramblings
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 👍👍
