We were tight on space on the drive where WSUS has been installed for the past several years, so I went for an uninstall and re-install.
Now, having completed the re-installation and ran the initial synchronisation, WSUS reports 5905 security updates, 1490 critical updates awaiting approval.
As these updates have already been approved and pushed out in the previous installation, I am inclined to decline all these updates, in order to save space.
We then start fresh and approve all updates from this point on.
I wanted experts to confirm if my logic is sound here, or if there is any possible problem with this approach.
