Windows 7 Resetbase backport

[harkaz]

UPDATE: I found a way to properly remove staged OS Editions (Working offline on Windows 7 Home Premium image).

However, the winsxs size was reduced only slightly: 70 MB

Rebase Beta Build has been reached.

 

Pending tasks:

 

Error handling and log output, Documentation, EULA, Release Trailer.

[harkaz]

Rebase RTM (1.0.20.16) is ready.

 

A release trailer will be uploaded in a few hours.

results pls

[harkaz]

Release trailer ready:

 

Win7 Pro x86 winsxs reduced from: 6.77 GB to 5.29 GB without the extreme option, 4.40 GB with the extreme option

[alacran]

Too much risk for only 1.5 GB (without the extreme option).

 

You can disable system restore and get more free GBs (just make an image of your system on an external USB drive to be safe).

@alacran Sent you a PM. Hope this will reassure you that rebase is reliable. And remember: you save 1.5 GB in addition to what system restore cleanup would save you.

Rebase Build 1.0.20.21

Release date: 30 Dec 2015

BUG FIX: Rebase will not cleanup updates added offline.

Reason: All updates installed offline are marked as pending and rebase was programmed not to remove files corresponding to updates that are marked as pending. Now rebase will ignore the pending indication if working offline.

Sounds very interesting!

 

How much space does it saves with the default recommended updates provided

by Windows Updates (~ 209 updates if I recall correct)?

[harkaz]

It saves about 2 GB on x64 systems, 1 GB on x86 systems.

[Luxman]

And, on a related note...

[harkaz]

It saves 2GB more after running this hotfix you mention.

[JFX]

2GB sounds good.

 

• Keeps only the active and base versions of every component in the component store. Runtime components which require multiple versions to be present (e.g CRT, ATL) are not affected

Just wonder, I'm no really friend of deleting files in WinSxS folder.

But wouldn't it be much safer to simple replace all superseded components with hardlink to the newest version?

[harkaz]

Rebase will leave placeholder-files in the winsxs folders of size ~30 bytes each.

Hardlinks will not decrease the size reported (including the wim file) and may cause problems in the future.

 

As a side note, rebase does not touch any hardlinks necessary to service future updates.

he'd have to do it manualy

as registry holds "bonds"
