Windows 10: Questions re: Expanding System Partition, Shrinking Windows Partition

Hello Everyone,

Hopefully I'm not duplicating a thread I haven't found. I'm running Windows Home v. 1803, Build 17134.829 on a Lenovo IdeaPad laptop. Windows Update failed to install the July CU (KB4507435) for v. 1803 with error code 0x800f0922 (possible cause: too-small system partition). This is the first time I've received this code so checked size of system partition and saw it is only 260 MB (screenshot follows):






This is the disk organization as provided by Lenovo; as you can see I have lots of free space but no unallocated space. If I need unallocated space to expand the system partition, I'll have to get it by shrinking the Windows partition. I have a few questions about this procedure:

1. Are there any special considerations for shrinking the Windows partition, e.g., defrag the disk first?
2. Must the unallocated space reside immediately next to the system partition to be considered contiguous? If shrinking the Windows partition places the unallocated space anywhere else, will I need a third-party disk management tool to enlarge the system partition?

I'm sure I'll need to resolve this before trying to update to v. 1903, which is now being offered, and I'll have to do the same to my husband's HP (don't want to mess up that one), so really need to have my ducks in a row before getting started.

Thanks in advance for your help.

:)

 

undo partition shrink

Hi,

If you accidentally shrink the volume of your SSD partition, there is an option to extend the volume as well. To extend the volume of your SSD partition, follow the steps below:

• Press Windows key + X on your keyboard and select Disk Management.
• Right-click the partition that you want to expand and click Extend Volume.
• Select the amount of space that you want to extend.

Keep us in the loop with the result.

 

undo partition shrink

Hi, disk management has limitations on the size of shrinking partition. Also extending partition with Disk Management, you must have unallocated space next to the partition which you need to expand. Otherwise, the button is grayed out.

I suggest you use a third party free disk partition manager to help you to
extend the partition.

 

Expanding my Windows partition.

AFAIK this is not possible with the windows partition manager,

i have never been able to sucsessfuly extent a lower partition into a higher one. what you need is a program that will move all the Data on Partition D to the end of it.

then the program will have to shrink the partition from the LEFT side so you can extend C: partition to the Right.





afaik windows cannot shrink a partition from the left side, only the right side.







Sorry if that dosnt make sence......
