I share a Windows laptop with my siblings, and I have the administrator account. The C: drive has only about 900 MB of free space left. My sister has Adobe Photoshop and Illustrator installed, but neither of us uses the other person's software. If I uninstall those programs from my account, will they disappear from all user accounts too? I'm also trying to understand whether installing programs for all users wastes extra storage, and what the best approach is for freeing up space safely.

Some installers let you choose between installing for the current user or everyone, while others decide automatically. The difference is mainly where the program files and user-specific settings go; either way, an installed program uses disk space.
With only 900 MB free, uninstall unused applications, clear temporary files, and move large personal files such as videos and downloads to another drive. Longer term, upgrading the laptop’s internal storage or using a reliable external SSD may be necessary. Avoid treating a cheap flash drive or microSD card as your main storage solution.
A system-wide installation usually does not create a separate full copy for every account. The main program files are shared, while each user keeps their own preferences and profile data. Installing it for all users can actually save space compared with maintaining separate installations.
Yes. If you uninstall Photoshop or Illustrator through Windows’ installed-apps settings, the program itself will be removed from the computer and will no longer be available to any user. Personal files, documents, and some settings may remain, so check for those separately before deleting anything.
