How to uninstall previous versions of Visual Studio

Installing the Visual Studio 2017 community edition, I realise I need to tidy up my PC in terms of previous Visual Studio installs (see below).  Is it simply a case of uninstalling, via Windows 10 Programs, the older editions, or are their shared programs I should be careful about?Screen grab

Hi,

If the machine isn't running any out of space then i would suggest to keep the older versions aside and run the newest along with older.
Yes, you can uninstall the old versions from Program/Features safely. Visual Studio CE 2017 uses it's own registry hive and it won't use the normal global assembly. So, there won't be any issues in clearing older versions.

If the machine isn't running any out of space
 I guess this is the issue.  VS2017 used 27GB to install, so my C drive has 40GB remaining out of 237GB. Is that getting into dangerous territory? Other partitions on the PC have masses of space; I didn't set it up correctly, obviously!

Hi,

If VS 2017 going to use 27GB then the installation pre-check itself get fails. So, the only option would be removing older versions. Again, this won't be enough as the days go, you will get into out of space again. Best option would be increase the C drive space using any third party utility like 'Partition Magic'. I hope it's a single disk allocated for 2 drives.

Thanks again.

40GB left after VS2017 successfully installed.

I agree with you though, best option is to increase C drive space.

I don't understand your final remark so I include the disk management:

Ah, sorry if that confuses you. I thought you have only 2 drives (C and D) but after seeing the screen shot i could see that you have 2 disks and 5 drives. In this case, check the page file size, probably that may be in huge size. If so, move that to different drive where you have more space.

1. Right Click Computer | Choose Properties

2. Click Advanced System Settings

3. Performance Tab | Click Settings

4. Advanced Settings Tab | Virtual Memory | Click Change

5. Uncheck Automaticaly manage page file

6. Clicking on disk will allow you to set paging file where you want

I would recommend you to have a page file on c drive in size at least 500MB this should be sufficient for having dumps. Then you can have bigger paging file on different drive which should help in respect to performance

Current auto set is 11264MB for C, none for other drives.  It says recommended is 1919MB.  I need to set initial and maximum, what should I use for each drive?

And I should still re-partition, moving some space from F drive to C?

As you can guess, I'm out of my comfort zone here!

you can't move space from F: to C: since they are on different physical disks. It looks like you've probably moved the user folders documents/music/pictures/videos to another drive if not right click on the folder and change the location tab.

Location tab?  Users is 20GB so it would make a difference.  Cut and paste it to F:?   If yes, would that upset any system defaults?

I am aware that the question has moved away from the original.  I could try to open a new Q, linking to this one.
